1 Unit5元素周期表As our picture of the atom becomes more detailed 随着我们对原子的描述越来越详尽,我们发现我们陷入了进退两难之境。

有超过100多中元素要处理,我们怎么能记的住所有的信息?有一种方法就是使用元素周期表。

这个周期表包含元素的所有信息。

它记录了元素中所含的质子数和电子数,它能让我们算出大多数元素的同位素的中子数。

它甚至有各个元素原子的电子怎么排列。

最神奇的是,周期表是在人们不知道原子中存在质子、中子和电子的情况下发明的。

Not long after Dalton presented his model for atom( )在道尔顿提出他的原子模型(原子是是一个不可分割的粒子,其质量决定了它的身份)不久,化学家门开始根据原子的质量将原子列表。

在制定像这些元素表时候,他们观察到在元素中的格局分布。

例如,人们可以清楚的看到在具体间隔的元素有着相似的性质。

在当时知道的大约60种元素中,第二个和第九个表现出相似的性质,第三个和第十个,第四个和第十一个等都具有相似的性质。

In 1869,Dmitri Ivanovich Mendeleev,a Russian chemist, 在1869年,Dmitri Ivanovich Mendeleev ,一个俄罗斯的化学家,发表了他的元素周期表。

Mendeleev通过考虑原子重量和元素的某些特性的周期性准备了他的周期表。

这些元素的排列顺序先是按原子质量的增加,,一些情况中, Mendeleev把稍微重写的元素放在轻的那个前面.他这样做只是为了同一列中的元素能具有相似的性质.例如,他把碲(原子质量为128)防在碘(原子质量为127)前面因为碲性质上和硫磺和硒相似, 而碘和氯和溴相似.Mendeleev left a number of gaps in his table.Instead of Mendeleev在他的周期表中留下了一些空白。

元素周期表随着对原子的描述越来越详尽,我们发现自己处于进退两难之地。

涉及着100种元素,我们怎样使这些元素保持连续性。

一种方法是用元素周期表,周期表巧妙地把原子信息列成表。

它记录着一种元素含有多少质子和电子,它使我们可以计算出大多数元素同位素的中子数。

周期表也存有每种元素的电子排列情况。

周期表最不寻常的是它的发展是在人们还不知道原子中含有质子和中子之前。

道尔顿提出了他的原子模型后不久(一种不可再分的粒子,它的质量取决于它的性质),化学家开始根据原子质量来排列元素。

当得出这种元素表,科学家们观测到元素的规律。

例如,那些出现在特定的位置的元素有某些相似性,这一观点已经越来越明显。

当时已知的约60种元素中,第二种和第九种元素表现出相似性,第三种与第十种元素,第四种与第十一种元素也都具有相似的性质。

1869年,门捷列夫,一个俄国化学家,提出了他们的元素周期表。

他列表时考虑到原子质量和元素某种特性的周期性。

这些元素主要是按原子质量递增的顺序排列的。

在特别情况下,门捷列夫把较重的元素放在较轻元素之前。

他这样做是为了在相同列上的元素有相似的化学性质。

比如,他把蹄(原子质量=128)放在碘(原子质量=127)之前,因为蹄的性质和硫及硒相似,而碘的性质和氯及溴相似。

门捷列夫在他的周期表中列了许多气体,在他的周期表中留下了一些空格,他非但没有将那些空格看成缺憾,反而大胆地预测还存在着未被发现的元素。

而且,他还预测了许多未知元素的性质。

在接下来的几年里,许多气体被填充在新发现的元素中。

这些元素的性质通常和门捷列夫预测的非常接近。

这些伟大创新的预测使门捷列夫的元素周期表被广泛接受。

众所周知,一种元素的性质主要取决于原子最外层能级上的电子数。

Na在它的最外层能级(第三层)有一个电子,Li原子在它的最外层(第二层)有一个单独的电子。

Na和Li的化学性质相似。

He和Ne原子已将所有能级排满,它们性质也相似,就是不容易发生化学反应。

20THE ROLE OF PROTECTIVE GROUPS IN ORGANIC SYNTHESIS20有机合成中保护基团的使用If a satisfactory protective group has not been located,the chemist has a number of alternatives:rearrange the order of some of the steps in the synthetic scheme so that a functional group no longer requires protection or a protective group that was reactive in the original scheme is now stable;redesign the synthesis,possibly making use of latent functionality(i.e.,a functional group in a precursor form;e.g.,anisole as a precursor of cyclohexanone).Or,it may be necessary to include the synthesis of a new protective group in the overall plan.如果找不到符合要求的保护基,化学家仍然具有大量可供选择的方法:重新安排合成系统中一些步骤的顺序,保证官能团不再需要保护或者在原来的系统中的活性保护基现在变得稳定;可能利用潜在的功能重新设计合成(也就是功能性基团以前驱体形式出现;例如:茴香醚作为环己酮的前驱体)。

或者,有必要在总体计划中包括新保护基的合成.22POLYMERS22聚合物The process by which small molecules undergo multiple combinations to form macromolecules is polymerization.Small molecules from which a macromolecule or polymer can be made are called monomers.Two types of polymerization are recognized: (1)condensation polymerization and(2)addition polymerization.A polymer-forming reaction involving elimination of a small molecule such as water or alcohol between monomer units is described as condensation polymerization.In addition polymerization, unsaturated or cyclic molecules add to each other without elimination of any portion of the monomer molecule.The empirical formula of the polymer is then,of course,the same as that of the monomer.小分子进行多重结合形成大分子的过程叫做聚合反应。

Unit1 The Roots ofChemistry 化学的起源1.Chemistry can be broadly defines as the science of molecules and their transf ormations.化学可以被广泛的定义为分子的科学和它们之间的转换。

和数学不同,化学在人类之前。

我们的星球(地球)上的生命和人类的外观很可能是化学进程的具体结果。

化学过程从历史的开端一直到现在都出现在人们的生活中。

最初,这些过程不在我们的掌控之中,例如,果汁的发酵,肉和鱼的腐烂,木头的燃烧。

后来我们学着去控制化学进程使用它来生产不同的产品,比如食物,金属,陶瓷和皮革。

在化学的发展上,主要区分为四个阶段:史前化学,希腊化学,炼金术,科学化学。

2.The early beginnings of chemistry were clearly motivated by practical needs of people .早期的化学显然是出于实际的需要。

火的发现为远古人提供了第一个机会去实现控制化学反应过程。

他们学会制备铜制物品,铜和其它材料是现成的。

.由于化学过程的使用早于人们的书写,因而没有书面记录有关它们的化学技巧。

可以判断他们的化学能力只有从考古的发现的各个手工艺品。

正如早期的数学发展,清楚的预示着实际需求影响着化学的发展。

但化学和数学在这个阶段可能没有互相影响。

如果它们影响了,但是没有记录证明这个。

3. Greek chemistry was based mainly on speculation rather than on experiment . 希腊化学主要基于猜测而不是实验。

这是所有古代希腊化学的一个共同特征。

古代希腊化学家实际是希腊哲学家。

所以不足为奇的是希腊人思考比实验更有兴趣。

实际上他们很少进行实验以外的思维实验。

对于数学来说这是一个好方法,但没有一个人把它推荐在物理、化学或生物科学上。

10级应用化学(2)班郑禄春 B2010063224Lessen 24 Chemical ReactionsConservation of mass and energy(质量与能量守恒)Two conservation laws(定律) apply to all chemical reactions: Energy can neitherbe created nor destroyed, and matter can neither be created nor destroyed. Thus the atoms taking part in a chemical reaction may be rearranged, but all the atoms present in the reactants must also be present in the products, and the total mass of thereactants must equal the total mass of the products.化学反应质量守恒和能量守恒两个守恒定律(定律)适用于所有的化学反应:能量既不能创造也不能消灭,物质也不能创造也不能消灭。

因此原子参与化学反应可能重新安排,但所有的原子出现在反应物必须包含在产品,反应物的总质量必须等于生产物的总质量。

What is a chemical reaction?A chemical reaction occurs when substances (the reactants) collide (碰撞) with enough energy to rearrange to form different compounds (the products). The changein energy that occurs when a reaction take place is described by thermodynamics(热力学)and the rate or speed at which a reaction occurs is described by kinetics (动力学) . Reactions in which the reactants and products coexist are considered to be in equilibrium(处于平衡). A chemical equation consists of the chemical formula(化学式)of the reactants, and the chemical formula of the products. The two areseparated by an →usually read as “yields”and each chemical formula is separated from others by a plus sign (加号) . Sometimes a triangle is drawn over the arrowsymbol to denote energy must be added to the substances for the reaction to begin.Each chemical formula may be preceded by a scalar (数量的) coefficient indicatingthe proportion (比例) of that substance necessary to produce the reaction informula. For instance, the formula for the burning of methane(CH4 + 2O2 → CO2 + 2H2O) indicates that twice as much O2 as CH4 is needed, and when they react, twiceas much H2O a s CO2 w ill be produced. This is because during the reaction, each atom of carbon needs exactly two atoms of oxygen to combine with, to produce the CO2,and every two atoms of hydrogen need an atom of oxygen to combine with to producethe H2O. If the proportions of the reactants are not respected, when they are forced to react, either not all of the substance used will participate in the reaction,or the reaction that will take place will be different from the one noted in theequation..什么是化学反应一个化学反应发生在物质(反应物)碰撞有足够的能量去重新排列,形成不同的化合物(产品)。

1化学的起源化学可以被广泛的定义为分子的科学和它们之间的转换。

和数学不同,化学在人类之前。

我们的星球(地球)上的生命和人类的外观很可能是化学进程的具体结果。

化学过程从历史的开端一直到现在都出现在人们的生活中。

最初,这些过程不在我们的掌控之中,例如,果汁的发酵,肉和鱼的腐烂,木头的燃烧。

后来我们学着去控制化学进程使用它来生产不同的产品,比如食物,金属,陶瓷和皮革。

在化学的发展上,主要区分为四个阶段:史前化学,希腊化学,炼金术,科学化学。

早期的化学很明显是被人们实际需要所激发的。

火的发现提供了史前人类开始控制化学反应的一次机会。

他们合成一些黄铜,青铜和其他易得材料的物品。

因为人类早期对化学过程的应用早于记载,所以没有关于它们化学技能的记录。

唯一可以判断它们化学能力的是考古的发现和不同的人造品。

正如早期数学发展一样,实际需要影响着化学的发展。

但是化学和数学在这个阶段很可能没有关系。

即使有,也没有记录来确定这些。

希腊化学主要建立在推测的基础上而不是在实验的基础上。

这是古希腊所有科学的普遍特征。

古希腊科学家实际上是哲学家,所以希腊对思考如此感兴趣盛于实验也就不足为奇了。

事实上他们很少做思考之外的实验。

这对数学是一个好的方法但是却不是对于物理,化学和生物科学。

然而,希腊人思考了许多关于自然和物质结构,他们可以被看作早期化学理论的创造者。

希腊引进了元素的概念总共提出了四种元素。

Thalesren认为所有的东西来自一种基本的物质,就是水。

Anaximenes,接受了元素的概念,但他认为来单独的元素自于空气中的物质。

Heraclitus,认为宇宙的基本的特点是不断变化的,把火作为永久变化的元素。

Empedocles摒弃了了单独元素的概念并引进了四种元素:水,空气,火和土,他也因为他的实验证明了空气是一种物质结构而出名。

火这种元素最早被柏拉图引用他猜测每种元素的粒子有特定的形体,尽管这种粒子太小以至于看不见。

因此,火的最小的粒子有规则的四面体结构,空气是八面体,水是二十面体,土是立方体(主要是六面体)。

Perhaps the most function definition of analytical chemistry is that it is "the qualitative and quantitative characterization of matter "也许对分析化学最实用的定义是:对物质进行定性和定量的表征。

描述这个词被广泛的使用。

它可能意味着在回答诸如“在洗发香波中是否如标签所示有维生素E”“这是一个白色阿司匹林片?”或“这块金属是铁或镍”等问题时,对样本中的化合物或元素进行鉴定。

这种类型的表征,要告诉我们什么是目前被称为的定性分析。

定性分析是鉴定一个或多个化学物质存在于一个材料中。

描述也可能意味着测定有多少种化合物或元素存在于一个样品中,回答“水杨酸在这个阿司匹林片中含量多少”或“这块钢中含有多少镍”等这些问题。

一种物质在一个样品中含量多少的这种测定被称为定量分析。

定量分析是测定某种化学物质在某个样品中的确切数量。

化学物质可能是某些元素、化合物或离子。

该药物可能有机和无机两种。

特性描述可能涉及到全分析,如构成一块钢的元素,或者表面分析,像鉴定绝大多数暴露在空气和水中的金属表面形成的氧化层的成分和厚度。

一个材料的特性描述可能超越化学分析所包括结构材料的确定,某个材料的物理性质的测量,以及物理化学参数的测量例如反应动力学。

这些测量的实例有:聚合物的结晶度(与非晶态相比)?物质失去结晶水的温度?“A牌”抗酸剂中和胃酸所需的时间?农药在阳光下的降解速度?这些不同的应用使分析化学成为广泛的学科之一在所有的科学学科中。

分析化学对于我们了解生物化学是至关重要的。

药物化学、地球化学、环境科学、大气化学,材料学中的反应像聚合物、金属合金和陶瓷技术以及许多其他科学领域。

For many years ,analytical chemistry relied on chemical reactions to identify and determine the components present in a sample.多年来,分析化学依赖化学反应,以确定出现在一个样本中的组分。

应用化学专业英语翻译Research and Development

应用化学专业英语翻译Research and Development

Unit 2 Research and Development研究和开发Research and development, or R&D as it is commonly referred to, is an activity which is carried out by all sectors of manufacturing industry but its extent varies considerably, as we will see shortly. Let us first understand, or at least get a feel for, what the terms mean. Although the distinction between research and development is not always clear-cut, and there is often considerable overlap, we will attempt to separate them. In simple terms research can be thought of as the activity which produces new ideas and knowledge whereas development is putting those ideas into practice as new process and products. To illustrate this with an example, predicting the structure of a new molecule which would have a specific biological activity and synthesizing it could be seen as research whereas testing it and developing it to the point where it could be marketed as a new drug could be described as the development part.研究和开发,或通常所称R&D是制造业各个部门都要进行的一项活动。

The laws of thermodynamics can be used to predict whether a particular chemical or physical transformation is theoretically possible under a given set of conditions. Furthermore, if a study shows that a desired change will not occur under the conditions assumed, thermodynamic principles can be used to determine how the conditions can be altered to make the change theoretically possible.我们一再提到伴随着化学和物理变化的能量效应。

1 Unit5元素周期表As our picture of the atom becomes more detailed 随着我们对原子的描述越来越详尽,我们发现我们陷入了进退两难之境。

有超过100多中元素要处理,我们怎么能记的住所有的信息?有一种方法就是使用元素周期表。

这个周期表包含元素的所有信息。

它记录了元素中所含的质子数和电子数,它能让我们算出大多数元素的同位素的中子数。

它甚至有各个元素原子的电子怎么排列。

最神奇的是,周期表是在人们不知道原子中存在质子、中子和电子的情况下发明的。

Not long after Dalton presented his model for atom( )在道尔顿提出他的原子模型(原子是是一个不可分割的粒子,其质量决定了它的身份)不久,化学家门开始根据原子的质量将原子列表。

在制定像这些元素表时候,他们观察到在元素中的格局分布。

例如,人们可以清楚的看到在具体间隔的元素有着相似的性质。

在当时知道的大约60种元素中,第二个和第九个表现出相似的性质,第三个和第十个,第四个和第十一个等都具有相似的性质。

In 1869,Dmitri Ivanovich Mendeleev,a Russian chemist, 在1869年,Dmitri Ivanovich Mendeleev ,一个俄罗斯的化学家,发表了他的元素周期表。

Mendeleev通过考虑原子重量和元素的某些特性的周期性准备了他的周期表。

这些元素的排列顺序先是按原子质量的增加,,一些情况中, Mendeleev把稍微重写的元素放在轻的那个前面.他这样做只是为了同一列中的元素能具有相似的性质.例如,他把碲(原子质量为128)防在碘(原子质量为127)前面因为碲性质上和硫磺和硒相似, 而碘和氯和溴相似.Mendeleev left a number of gaps in his table.Instead of Mendeleev在他的周期表中留下了一些空白。

Answer: The scientific method is a logical and systematic approach to problem solving in science. It consists of several key steps including observation, hypotheses,experimentation, and theory. Scientists use the scientific method to answer questions and solve problems by gathering data through observation and experimentation, forming hypotheses based on that data, testing those hypotheses through experimentation, andfinally developing theories to expln the results of those experiments.2.Describe the properties of matter and how they are used to differentiate between substances. Answer: Properties of matter can be either physical or chemical. Physical properties include mass, volume, density, color, melting point, boiling point, and solubility. These properties can be used to differentiate between substances by comparing their physical properties. Chemical properties include reactivity, flammability, and toxicity. These properties are used to differentiate between substances based on their chemical behavior under certn conditions.3.Describe the structure of an atom and the role that subatomic particles play in determining chemical behavior. Answer: Atoms have a central nucleus that contns protons and neutrons. Electrons orbit around the nucleus in shells or orbitals. Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge. The number of protons in the nucleus determines the element to which the atom belongs, while the number of electrons in the outermost shell determines the chemical behavior of the atom.4.Expln the difference between a mixture and a pure substance. Give examples of each. Answer: A mixture is a combination of two or more substances that are not chemically bonded together. Mixtures can be either homogeneous or heterogeneous. A homogeneous mixture is a uniform mixture where the composition is the same throughout, such as saltwater. A heterogeneous mixture is a non-uniform mixture where the composition varies, such as oil and water. A pure substance is a substance that cannot be broken down into simpler substances by chemical means. Examples of pure substances include elements such as gold and silver, and compounds such as water and carbon dioxide.5.Expln the difference between a physical change and a chemical change. Give examples of each. Answer: A physical change is a change in the physical properties of a substance, such as shape, size, or state of matter, without changing its chemical composition. Examples of physical changes include melting ice, boiling water, and cutting paper. A chemical change is a change in the chemical properties or composition of a substance, resulting in the formation of a new substance or substances. Examples of chemical changes include burning of wood, digestion of food, and rusting of iron.。

Unit10 Nomenclature of Hydrocarbons碳氢化合物的命名Alkanes烷烃理想的,每一种化合物都应该由一个明确描述它的结构的名称,并且通过这一名称能够画出它的结构式。

为了这一目的,全世界的化学家接受了世界纯粹与应用化学会(IUPAC)建立的一系列规则。

这个系统就是IUPAC系统,或称为日内瓦系统,因为IUPAC的第一次会议是在瑞士日内瓦召开的。

不含支链的烷烃的IUPAC命名包括两部分(1)表明链中碳原子数目的前缀;(2)后缀-ane,表明化合物是烷烃。

用于表示1至20个碳原子的前缀见表表中前4个前缀是由IUPAC选择的,因为它们早已在有机化学中确定了。

实际上,它们甚至早在它们成为规则之下的结构理论的暗示之前,它们的地位就确定了。

例如,在丁酸中出现的前缀but-,一种表示在白脱脂中存在的四个碳原子的化合物(拉丁语butyrum白脱(黄油))。

表示5个或更多碳原子的词根来源于希腊或拉丁词根。

含取代基的烷烃的IUPAC名称由母体名称和取代基名称组成,母体名称代表化合物的最长碳链,取代基名称代表连接在主链上的基团。

来源于烷烃的取代基称为烷基。

字母R-被广泛用来表示烷烃的存在.烷烃的命名是去掉原烷基名称中的-ane加上后缀-yl。

例如,烷基CH3CH2-称为乙基。

CH3-CH3乙烷(原碳氢化合物)CH3CH2-乙基(一个烷基)下面是IUPAC的烷烃命名规则:1. 饱和碳氢化合物称为烷烃。

2. 对有支链的碳氢化合物,最长的碳链作为主链,IUPAC命名按此主链命名。

3. 连接在主链上的基团称为取代基。

每一取代基有一名称和一数字.这一数字表示取代基连接在主链上的碳原子的位置。

4. 如果有多于一个的相同取代基,要给出表示支链位置的每个数字。

而且,表示支链数目的数字由前缀di-,tri-,tetra-,penta-等表示。

5. 如果有一个取代基,主链碳原子编号从靠近支链的一端开始,使支链位号最小。

如果有两个或多个取代基,支链从能使第一个取代基位次较小的一侧编号。

6. 如果有两个或多个取代基,它们按字母顺序排列。

当排列取代基时,前缀iso-(异)和neo-(新)也按字母排列,前缀sec-(仲)和tert-(特)在字母排列中忽略此外,按字母排列取代基时,表示倍数的前缀2,3,4等也被忽略。

Alkenes烯烃烷烃的碳原子间只有单键。

烯烃在两个碳原子间有双键(两个键)。

考虑到两个碳原子间以双键相连。

因为双键用去了两个碳原子的共4个电子。

所以只剩下4个电子以供成键。

想到一对单键需要一对共用电子,双键占有两对共用电子。

化合物成为CH2=CH2。

分子式为C2H4。

它叫做乙烯。

当3个碳原子组成一个在两个碳之间含有双键的链C=C -C,需要有多少氢与之相连以满足成键的需要?答案是6,结构式为CH2=CH-CH3。

分子式为C3H6。

这种化合物的名称是丙烯。

注意这类化合物以-ene结尾,对所有的烯都是如此。

注意,除结尾处用-ene代替-ane之外,这些化合物的命名与那些烷烃的命名类似。

比较乙烷(C2H4)和乙烯(C3H6)的结构。

CH3-CH3乙烷 CH2=CH2乙烯三个碳的烷是丙烷,三个碳的烯是丙烯。

同样,4个碳的烷是丁烷,而相应的烯是丁烯。

烯的通式是CnH2n。

在乙烯中氢原子数目是碳原子的2倍。

这样,辛烯有8个碳和16个氢,15个碳的烯的分子式为C15H30 乙烯基是这样的结构CH2=CH-。

氯乙烯在制造业中其类似产品用作地板转、雨衣、纤维和家具膜。

然而,有迹象表明工作时间暴露于氯乙烯中的几位工人死于一种罕见的肝癌。

而且,暴露于氯乙烯中还与某些特定的出生缺陷有关。

氯乙烯的结构为CH2=CHCl。

氯乙烯用于制造聚氯乙烯(PVC),一种塑料。

注意,1-丁烯表明双键开始于第一个碳原子。

相似的。

H3C-CH=C(CH3)2称为2-甲基2-丁烯。

如果烯含有两个双键,称为二烯;三烯含有三个双键。

1,3-丁二烯用于制造汽车轮胎,白三烯与人的过敏反应有关。

Alkynes 炔烃想象2个碳由三键连接-C≡C-,需要几个氢与两个碳相连以满足成键?答案是2,所以这种化合物的分子式为C2H2。

这种化合物称为乙炔。

它的结构式为H-C≡C-H(H:C┇┇C:H)乙炔又称为acetylene。

这个词并不准确。

因为后缀-ene代表双键,而此化合物的碳原子间是以三键相连的。

如果三个碳成键而且其中两个碳以三键相连C≡C-C,只有4个氢能放在碳的周围以满足成键。

化合物为H-C≡C-CH3。

其分子式为C3H4。

这种化合物称为丙炔。

这两种化合物,乙炔和丙炔,都是炔。

它们在其中两个碳之间含有三键,它们的名称以-yne结尾。

炔的通式为CnH2n-2。

己炔,含有6个碳,式为C6H2×6-2或C6H10。

相应的,辛炔的分子式为C8H14。

炔是相对较少的化合物,而且很少出现在人体中。

与烯相似,炔的命名使炔键的位次最小。

4-甲基-2-己炔。

Nomenclature of Derivative 衍生物的命名Alcohols 醇在IUPAC系统中,含有一OH的最长碳链作为母链。

为了表明该化合物为醇,将相应的烷烃名称的后缀一e变为一ol,并加上数字来表示羟基的位置。

母链的编号应使一OH 的位次尽可能小。

醇的习惯命名是命名带一OH的烷基,并加上词“醇”。

在IUPAC系统中,带有两个羟基的化合物称为二醇,带有三个羟基的称为三醇,等等。

注意在这些化合物的IUPAC命名中其母体后缀一e被保留下来了。

相邻碳原子上带有两个羟基的化合物的习惯命名为glycols (二醇)。

乙二醇和丙二醇分别是由乙烯和丙烯合成的,所以它们的名称类似。

带有一OH和C=C基团的化合物称为不饱和醇,因为有碳一碳双键的存在。

在IUPAC 系统中,它们被命名为醇,而且母链的命名要使一OH具有最小编号。

含有双键的碳链通过把中缀由一an变为一en表示。

同时用编号表示碳碳双键和羟基的位置。

Ethers 醚在IUPAC系统中,醚的命名是选择最长的碳链作为母链,并把一OR基团命名为烷氧基取代基。

下面是低分子量醚的IUPAC命名。

醚的俗名是按照字母表顺序命名与氧相连的烷基并加上词“醚”。

化学家们基本上都使用低分子量醚的俗名。

例如,尽管乙氧基乙醚是CH3CH2OCH2CH3的IUPAC命名,但它很少使用;的确,化学家使用二乙基醚、乙醚,甚至更普通些使用简单醚这样的名称。

Amines 胺在IUPAC命名系统中,最长的含有胺基的碳链作为母体,一NH2作为取代基,就像一Cl、一NO2等一样。

通过前缀amino—表示它的存在,并用数字表示它的位置。

如果有多于一个的烷基与氮相连,含有最长碳链的烷基为母体,其他取代基命名为烷基并加上N—表示它与胺中的氮原子成键。

在这些及随后的例子中,首先给出IUPAC命名。

为了避免在普通命名下面再次列出相同的结构式,当有俗名时,我们在IUPAC命名下面括弧中列出俗名。

正如在阅读中将发现一样,普通命名比IUPAC命名的应用更为广泛。

含有两个或多个胺基的化合物命名中带有2—,3 —等前缀以表示多取代以及表示每个取代基位置的数字。

下面是三种胺。

第一种,1,6 —二胺基己烷,是合成尼龙一66的两种起始原料之一。

后两种是动物尸体腐烂后的产物,正如它们的俗名表示的一样。

如果一NH2是两种或多种取代基之一,用前缀表示,如下述例子:化合物C6H5NH2命名为苯胺,并成为其同系物的母体名称。

有几种苯胺的简单衍生物专有的以其俗名命名。

如甲苯胺(其邻同分异构体已列出)当一个氮原子上连有4个有机基团(不论是脂肪基还是芳香基),这些化合物叫做铵盐,如下面的例子:对醛酮的IUPAC命名遵循熟悉的模式,即选择含官能团的最长碳链作为母体化合物。

醛的命名是把母体的后缀一e变成一al。

因为醛基只能出现在碳氢链的一端且必须把醛基碳作为起始碳原子1,它的位置是独一无二的,因此不需要用数字表示它的位置。

下面是几种低分子量醛的IUPAC命名。

对不饱和醛(也就是说,还含有烯),碳碳双键的存在用中缀一en—表示,如下面的例子所示;对于同时有中缀和后缀的分子,后缀的位置表示其编号部分。

在IUPAC中保留的醛的俗名是安息香醛和肉桂醛。

Benzaldehyde 安息香醛cinnamaldehyde 肉桂醛在IUPAC系统中,酮的命名是选择包括羰基的最长碳链作为母链,通过把后缀一e换成一one来表明酮的存在。

母链编号从使羰基的位次最小的一端开始。

IUPAC系统保留了俗名丙酮和苯乙酮。

下面是一些例子:2-propanone acetone 2-butanone 4-methyl-3-hexanone 2 —丙酮,丙酮、 2—丁酮、 4—甲基一3 —己酮,2-methylcyclohexanone acetophenone p-chloroacetophenone 2 —甲基环己酮,苯乙酮, p—氯苯乙酮。

对于那些多于一个官能团的化合物,即有不止一个官能团需用词缀表示的化合物的命名,IUPAC系统建立了一个被称为官能团优先顺序的规则。

官能团优先顺序我们在表中给出。

你将知道当一个官能团有较高优先顺序的时候如何表示,而具有较低优先顺序又如何表示。

有机酸的IUPAC命名选择含羧基的最长碳链作为母体化合物。

羧基通过把母体化合物的后缀一e变成一oic acid (酸)来表示。

由于在母体中羧基碳原子的编号总是碳1,所以没有必要给出它的编号。

下面是一些有机酸的结构式及IUPAC命名,注意IUPAC系统保留了俗名蚁酸和醋酸。

如果羧酸含有一个不饱和键,中缀将由一an—变为一en—以表示双键的存在。

双键的位置由数字表示,就像普通烯一样。

下面是两种有机酸,都含有双键,括号中是他们的俗名。

在IUPAC系统中,羧基的优先顺序比大部分有机基团高,包括羟基和醛酮的羰基(表。

在取代羧酸中,一OH的存在用前缀“羟基”表示,醛酮的羰基的存在用前缀一oxo (羰基)表示,如下面的例子所示:母体化合物含2个羧基的二羧酸加上后缀“二酸”表示。

IUPAC系统保留了一些俗名,如草酸、丙二酸、琥珀酸和酒石酸。

草酸的名称来源于它的一个生物来源,即酢浆草类植物,其中之一叫大黄。

草酸用作汽车水箱的清洗剂、以及纺织品修整和清洁。

酒石酸是葡萄汁发酵成葡萄酒的副产物。

它以钾盐的形式被收集并以酒石的名称出售。

己二酸是合成尼龙一66的单体之一。

1985年,美国化学公司生产了 163 亿镑己二酸,全部用于合成尼龙一66。

三羧酸或多羧酸以后缀一三羧酸、一四羧酸等命名。

三羧酸的例子是2—羟基一1,2,3 —丙三羧酸,它的俗名是柠檬酸,也是IUPAC系统的保留名称。

柠檬酸在代谢过程,即通常所说的三羧酸或克雷布氏循环中起主要作用。

Unit 12 What is Analytical Chemistry什么是分析化学也许对分析化学最实用的定义是:对物质进行定性和定量的表征。
