Explain what is meant by the term "stoichiometry" in chemistry.答案:Stoichiometry is the calculation of the relative quantities of reactants and products in a chemical reaction.It is based on the law of conservation of mass and involvesthe use of balanced chemical equations and the molar massesof substances to determine the amounts of reactants needed to produce a certain amount of product or the amounts ofproducts formed from a given amount of reactant.2. Describe the difference between a physical change and a chemical change.答案:A physical change is a change in the state or form of a substance without altering its chemical composition. Examples include melting, freezing, and boiling. A chemical change, on the other hand, involves a change in the chemical composition of a substance, resulting in the formation of new substances. Examples include combustion and rusting.3. What are the three main types of chemical bonds, and givean example of each.答案:The three main types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds. An ionic bond is formed when electrons are transferred from one atom to another, resulting in the formation of oppositely charged ions. An example is the bond between sodium (Na) and chloride (Cl) in table salt (NaCl). A covalent bond is formed when two atoms share electrons, as seen in water (H2O) where hydrogen atoms share electrons with oxygen. Metallic bonds occur in metals, where a "sea" of delocalized electrons is shared among positively charged metal ions, as in sodium metal。

Aspects of synthesis could involve either developing new, more specific reagents for controlling particular functional group interconversions, i.e. developing synthetic methodology or complete synthesis of an entirely
the development. 2. Types of Industrial Research and Development The applied or more targeted type of research and
development commonly carried out in industry can be of several type and we will briefly consider each. They are: (i) product development, (ii) process development, (iii) process improvement and (iv) applications development. Even under these headings there are a multitude of aspect so only a typical example can be quoted in each case. The emphasis on each of these will vary considerably within the different sectors of the chemical industry. Product development. Product development

1.The explosives growth in petrochemicals in the 1960s and 1970s was largely due to the enormous increase in demand for synthet ic polymers such as polyethylene, polypropylene, nylon, polyesters and epoxy resins.石油化工在60年代和70年代的迅猛发展主要是由于人们对于合成高聚物如聚乙烯、聚丙烯、尼龙、聚脂和环氧树脂的需求巨大增加。

2.The difficulty cones in deciding at which point in this sequence the particular operation ceases to be part of the chemical industry’s sphere of activities. 困难在于如何决定在一些特殊的生产过程中哪一个环节不再属于化学工业的活动范畴。

举一个特殊的例子来描述一下这种困境。

3.The chemical engineer must also work closely with mechanical, electrical, civil, and metallurgical engineers in order to design and operate the physical equipment in a plant--the reactors, tanks, distillation columns, heat exchangers, pumps, compressors, Control and instrumentation devices, and so on. 化学工程师还必须与机械、电子、土木建筑和冶金工程师密切协作以设计和操作工厂的机械设备—反应器、槽、蒸馏塔、热交换器、泵、压缩机、控制器和仪器设备等等。

Unit 1 Chemical Industry化学工业Although the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all inorganic chemicals. The organic chemicals industry started in the 1860s with the exploitation of William Henry Perkin’s discovery if the first synthetic dyestuff—mauve. At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time. The experience gained with this was to stand Germany in good stead, particularly with the rapidly increased demand for nitrogen-based compounds (ammonium salts for fertilizers and nitric acid for explosives manufacture) with the outbreak of world warⅠin 1914. This initiated profound changes which continued during the inter-war years (1918-1939).1.化学工业的起源尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。

化学工艺流程题 英语

化学工艺流程题英语Title: Chemical Process Flow: A Technical Overview.The chemical industry, encompassing a diverse range of processes and reactions, plays a pivotal role in the modern world. This industry not only produces essential materials like plastics, fertilizers, and pharmaceuticals but also contributes significantly to the economy and employment opportunities. Chemical process flows, the backbone of the industry, are complex systems that involve multiple steps, reactions, and equipment. This article aims to provide a technical overview of chemical process flows, focusing on their design, optimization, and significance in the chemical industry.1. Introduction to Chemical Process Flows.Chemical process flows refer to the sequential steps and operations involved in converting raw materials into desired products. These flows involve various unitoperations such as mixing, heating, cooling, separation,and reaction. Each step is carefully designed and optimized to ensure efficient and cost-effective production. The design of chemical process flows requires a deep understanding of chemistry, physics, and engineering principles.2. Key Elements of Chemical Process Flows.The design of chemical process flows involves several key elements. These include:Raw Materials: The selection of suitable raw materials is crucial as it directly affects the quality and cost of the final product.Reactors: Reactors are the heart of chemical processes, where the desired chemical reactions occur. They are designed to withstand high temperatures, pressures, and corrosive environments.Separation Units: These units separate the desiredproduct from unwanted by-products and impurities. Common separation techniques include distillation, crystallization, and adsorption.Utility Systems: These systems provide the necessary utilities such as steam, cooling water, and compressed air required for the process.Control Systems: Automation and control systemsmonitor and control the process parameters, ensuring consistent product quality and safety.3. Optimization of Chemical Process Flows.The optimization of chemical process flows is crucialfor enhancing productivity, reducing costs, and minimizing environmental impacts. Several techniques are employed for this purpose, including:Process Simulation: Software tools are used tosimulate the process, predicting performance andidentifying potential bottlenecks.Process Control: Advanced control systems monitor and adjust process parameters in real-time, ensuring optimal operation.Energy Efficiency: Measures such as heat recovery and waste heat utilization are implemented to reduce energy consumption.Sustainability: The use of renewable resources, waste minimization, and emission control techniques contribute to sustainable chemical production.4. Significance of Chemical Process Flows in the Chemical Industry.Chemical process flows play a pivotal role in the chemical industry. They determine the efficiency, cost-effectivenesss, and sustainability of production processes. Well-designed process flows can lead to increased productivity, reduced waste, and improved product quality. This, in turn, translates into competitive advantages forchemical companies, enabling them to meet market demands and capitalize on growth opportunities.Moreover, chemical process flows have a significant impact on the environment. Optimized processes can minimize emissions, reduce energy consumption, and promote the use of renewable resources. This contributes to sustainable development and helps mitigate the negative environmental impacts of the chemical industry.5. Conclusion.In conclusion, chemical process flows are integral to the success of the chemical industry. They require careful design, optimization, and continuous improvement to ensure efficient and sustainable production. With the evolving technology and increasing focus on sustainability, the future of chemical process flows looks promising. We can expect more innovative and efficient processes that not only drive economic growth but also contribute to a better and more sustainable world.。
