多胺型聚苯乙烯树脂的合成及对Cu2+的吸附性能
CHEMICAL INDUSTRY AND ENGINEERING PROGRESS 2016年第35卷第10期·3258·化工进展多胺型聚苯乙烯树脂的合成及对Cu2+的吸附性能孟启,吕科翰,夏丰敏,倪梦燚(常州大学石油化工学院,江苏常州 213164)摘要:以聚苯乙烯树脂为起始原料,经氯乙酰化后与四乙烯五胺反应,合成了一种含四乙烯五胺功能基的多胺型聚苯乙烯树脂。
考察了溶剂、物料比、时间和温度等反应条件对树脂合成的影响,研究了树脂对Cu2+的吸附性能。
结果表明,合成反应在THF溶剂中室温即可顺利进行,所得树脂全交换容量为7.45mmol/g。
树脂对Cu2+的吸附可以用准二级动力学方程来描述,液膜扩散为吸附主要控制步骤,吸附符合Langmuir等温方程,为单分子层吸附,饱和吸附量为46.15 mg/mL。
对于Cu2+、Ni2+混合溶液,该树脂可以选择性吸附其中Cu2+。

Effects of reaction solvent,mole ratio of raw materials,time and temperature were discussed. The adsorption property of the polyamine-type polystyrene resin for Cu2+ was also studied. The results show that the synthetic reactions can take place smoothly in THF at room temperature and the complete exchange capacity of the synthesized resin is 7.45 mmol/g. The adsorption processes of Cu2+ can be described by pseudo-second order kinetic equation. The main control step of resin adsorption for Cu2+ is governed by liquid film diffusion. The adsorption of Cu2+ belongs to the Langmuir adsorption model and was valid for single-layer adsorption. The saturated adsorption capacity of the synthesized resin toward Cu2+ is 46.15mg/mL. The Cu2+ can be removed selectively from the mixed solution of Cu2+ and Ni2+ by the synthesized resin adsorption.Key words:tetraethylenepentamine;resin;synthesis;adsorption;copper ion多胺结构对一些金属离子具有良好的螯合作用,通过多胺分子对聚合物的化学修饰可以制得多种具有特殊功能的新型材料[1-4],其中以多乙烯多胺为功能基的多胺型树脂具有结构稳定、用途广泛的特点,在合成技术研究和应用领域拓展等方面引起了人们广泛的关注[5-7]。

结果表明,离子液体的密度、黏度随温度的升高而减小,而电导率随温度的升高而增大。
采用自然对数方程关联四种离子液体的密度,根据实验值计算到了离子液体体积性质;采用VFT 方程关联离子液体黏度和电导率,其中密度与电导率的实验值与模型相关系数R 2达到0.9999,黏度相关系数R 2达到0.99999,实验测定的数据与模型一致;四种离子液体的热稳定性相近,分解温度均在271.9~278.6℃范围内;瓦尔登规则分析表明,四种烷基咪唑磷酸酯离子液体符合Walden 规则,而[EMIM][DMP]和[EMIM][DEP]被归类为“good ionic liquids ”。

Some important volumetric properties, including the isobaric thermal expansion coefficients, molecular volume, standard entropy and lattice potential energy were calculated from the experimental density values. The thermal gravimetric analysis was performed in the temperature range of 35℃ to 700℃, resulting in thermal decomposition temperatures up to 271.9—278.6℃. The Walden rule analysis demonstrated that four phosphate ionic liquids complied with the Walden rule well, while [EMIM][DMP] and [EMIM][DEP] were classified as “good ionic liquids ”.Keywords: alkyl imidazolium phosphate ionic liquids; density; viscosity; conductivity; thermal stability研究开发DOI :10.16085/j.issn.1000-6613.2023-1722收稿日期:2023-09-28;修改稿日期:2023-12-05。

HRAC-Classification of Herbicides According to Mod
Classification of Herbicides According to Mode of ActionFarmers, advisors and researchers should know which herbicides are best suited to combat specific resistant weeds. To support the use of herbicides suitable for resistance management the enclosed classification of herbicides is proposed.The herbicides are classified alphabetically according to their target sites, modes of action, similarity of induced symptoms or chemical classes.If different herbicide groups share the same mode or site of action only one letter is used. In the case of photosynthesis inhibitors subclasses C1, C2 and C3 indicate different binding behaviour at the binding protein D1 or different classes. Bleaching can be caused by different ways. Accordingly subgroups F1, F2 and F3 are introduced. Growth inhibition can be induced by herbicides from subgroups K1, K2 and K3. Herbicides with unknown modes or sites of action are classified in group Z as "unknown" until they can be grouped exactly.Classification of HerbicidesIn order to avoid confusion with I and O categories J and Q are omitted. New herbicides will be classified in the respective groups or in new groups (R, S, T...).Since the system was in part developed in co-operation with the "Weed Science Society of America (WSSA)" new herbicides should be categorised jointly by HRAC and WSSA.For reference the numerical system of the WSSA is listed, too.The aim of HRAC is to create a uniform classification of herbicide modes of action in as many countries as possible.Such a classification system can be useful for many instances but there are cases where weeds exhibit multiple resistance across many of the groups listed and in these cases the key may be of limited value.The system itself is not based on resistance risk assessment but can be used by the farmer or advisor as a tool to choose herbicides in different mode of action groups, so that mixtures or rotations of active ingredients can be planned.For a figure of the chemical groups involved each HRAC Group, click on the letter in the table below. A synoptic graphic of the HRAC groups is also available.The WSSA and HRAC systems differ in minor ways. Herbicides in italics are listed on the HRAC classification system but are not listed on the WSSA classification.January 2005 HRAC: Herbicide classificationRemarks:According to information and comments following herbicides are classified in the January 2005 version in HRAC (WSSA) groups:B (2): cancelled: #9; #9; procarbazone Approved ISO name: propoxycarbazone E (14): cancelled: pyrazogyl Approved name: pyraclonil。

答案:1.2 NaCl 与KBr 各1mol 溶于水中所得的溶液与NaBr 及KCl 各1mol 溶于水中所得溶液是否相同?如将CH 4及CCl 4各1mol 混在一起,与CHCl 3及CH 3Cl 各1mol 的混合物是否相同?为什么? 答案:NaCl 与KBr 各1mol 与NaBr 及KCl 各1mol 溶于水中所得溶液相同。
因为两者溶液中均为Na +,K +,Br -, Cl -离子各1mol 。
由于CH 4与CCl 4及CHCl 3与CH 3Cl 在水中是以分子状态存在,所以是两组不同的混合物。

QuEChERS结合气相色谱-串联质谱法测定室内灰尘中的37种液晶单体化合物
第43 卷第 3 期2024 年3 月Vol.43 No.3405~412分析测试学报FENXI CESHI XUEBAO(Journal of Instrumental Analysis)QuEChERS结合气相色谱-串联质谱法测定室内灰尘中的37种液晶单体化合物李辉,施致雄*(首都医科大学公共卫生学院,北京100069)摘要:建立了一种简单易行且灵敏准确的测定室内灰尘中液晶单体化合物(Liquid crystal monomers,LCMs)的方法。
灰尘样品中加入13C-多氯联苯和13C-多溴联苯醚作为内标,采用二氯甲烷进行提取,萃取液加入无水硫酸钠后采用混合吸附剂(N-丙基乙二胺和十八烷基键合硅胶)净化,随后采用气相色谱-串联质谱在动态多反应监测(dMRM)模式下测定,内标法定量。
对仪器分析参数、提取溶剂和吸附剂进行了优化。
结果显示在优化条件下,37种液晶单体在0.1~50 ng/mL范围内线性良好,方法检出限为0.02~1.56 ng/g;在两加标水平下的平均回收率为65.3% ~ 137%,相对标准偏差(RSD)为0.90% ~ 24%。
通过对实际样本的检测,发现在北京所采集的室内灰尘中有22种LCMs的检出率在50%以上,表明室内环境已普遍存在LCMs污染。
该方法操作简单,溶剂消耗少,灵敏度和稳定性良好,可用于大规模室内环境污染监测。

In this study,a sim⁃ple,sensitive and accurate analytical methodology was established for the determination of LCMs in indoor dust. For the sample pretreatment,dust samples were mixed with stable isotope substituted in⁃ternal standards(ISs),namely polychlorinated biphenyls(13C-PCBs)and polybrominated biphenyl ethers(13C-PBDEs),and then extracted by dichloromethane(DCM),and the supernatant was subse⁃quently transferred to another tube after centrifugation.With anhydrous sodium sulfate adding into the extracted solution,the solution was further purified by a mixture absorbent of primary secondary amine(PSA) and octadecyl-modified silica(C18). Finally,37 LCMs were simultaneously tested on a gas chromatography-tandem mass spectrometry performed under dynamic multi-reaction monitoring mode(dMRM),and the internal standards were used for quantification.Instrumental parameters,the use of extraction solvents and absorbents were optimized. Under the best condition,the 37 LCMs exhibited good linearity in the range of 0.1-50 ng/mL,with a method detection limit of 0.02-1.56 ng/g. The average recoveries of the tested substances at two spiking levels was 65.3%-137%,with relative standard deviations(RSDs) of 0.90%-24%. Twenty real indoor dust samples collected in Bei⁃jing were tested. The contents of total LCMs in dust ranged from 38.9 to 125 ng/g,and the average contents of the individual LCMs were from 0.044 7 to 25.1 ng/g. Twenty-two LCMs out of the 37 tar⁃get LCMs presented relatively high detection frequency(higher than 50%),which indicated the ubiq⁃uity of LCMs in indoor environment in Beijing. With the spread of smart electronic devices,it is fore⁃seeable that the pollution of LCMs in indoor environment will be rather serious.

反复分批式反应提高磷脂酰丝氨酸的生产能力
CHEMICAL INDUSTRY AND ENGINEERING PROGRESS 2016年第35卷第4期·1180·化工进展反复分批式反应提高磷脂酰丝氨酸的生产能力封娟娟1,朱南南1,邓杨敏1,韩晓玲2,张小里1,赵彬侠1(1西北大学化工学院,陕西西安 710069;2西安力邦制药有限公司,陕西西安 710075)摘要:磷脂酶D(PLD)催化大豆磷脂合成磷脂酰丝氨酸(PS)反应是在油-水两相体系中进行的,大豆磷脂(PC)溶于有机相中,L-丝氨酸溶于水相中,但反应过程中产生副产物——胆碱,抑制酶的催化反应速率,需及时移除胆碱。
本文主要采用反复分批式反应来解决这一问题。
并考察了增大底物PC的浓度,PS的收率大大降低。
低底物PC浓度下,添加不同浓度胆碱,转酯速率及PS收率都降低;高底物PC浓度下,采用反复分批式反应去除胆碱,转酯反应速率提高38%,PS收率达67%。
研究表明反复分批式操作是一种生产磷脂的新型工艺,其中PS的生产能力明显提高,而且重复10次反应后,固定化酶活力仍保持58%,纳米SiO2固定化磷脂酶D较好地适用于反复分批式反应。

However,the by-product choline restrains the enzyme-catalyzed reaction rate and should be removed in time. In order to solve this problem,we adopted the repeated batch reaction.Increasing the substrate (PC) concentration decreased the yield of PS greatly. When various concentrations of choline chloride were added into the reaction mixture at low PC concentrations,there was a significant decrease in transphosphatidylation rate and the yield of PS. The using of repeated batch reaction was examined at high PC concentration to remove choline,the transphosphatidylation rate increased by 38%,and PS yield was 67%. The paper reported that the repeated batch operation is a novel technology for the synthesis of phosphlipid and increased the productivity of PS significantly.And the immobilized enzyme activity remained 58% after ten batches and nano-SiO2-immobilized-PLD was suitable for repeated batch reaction.Key words:phosphatidyserine; immobilized phospholipase D; repeated batch reaction; choline磷脂酰丝氨酸(phosphatidyiserine,简称PS)是一种稀有磷脂,虽然在人体内数量极其稀少但功能显著,具有提高大脑机能、集中注意力、改善记忆力、缓解压力、促进用脑疲劳的恢复、平衡情绪、修复大脑损伤等功效[1]。

PDE5-inhibitors have become the first-line standard therapy in erectile dysfunction (1). Nevertheless, this therapy is not cause dependent and has a success rate at standard doses of 77% (1). This type of medication is not indicated for patients treated with certain cardiac medicaments or with other known contraindications. PDE5-inhibitors have some, not always harmless, side effects who prevent patients from continuous use. Furthermore, the medication is not covered by most health insurances and therefore is not affordable for many patients. Virag et al. reported, that after 2 years from the completion of the trial only 32% of the patients (17.2% of the initial cohort) were still using sildenafil as a single treatment (2). In those patients who do not respond to sildenafil, a structural alteration in the components of the erectile mechanism can be suspected (1). Penile erection is believed to be the result of venous occlusion along with increased arterial inflow and cor- poreal smooth muscle relaxation. A failure of the closing mechanism of the penile veins is one of the most com- mon causes of vasculogenic erectile dysfunction. In the past procedures as deep dorsal vein ligation have been performed to recover erectile function (10).
