摘要：传统化学工业给环境带来了的污染越来越严重，人们意识到了保护环境的重要性，由此人们提出了绿色化学的概念。最近几年，大家越来越关注环境保护，所以实行绿色化学是非常有必要的。二氯代苯乙酮类化合物是重要的有机合成中间体，虽然现在有许多合成此类化合物的方法，但这些方法都存在着以下缺点：反应时间长、运用有毒的反应试剂、后处理麻烦等，这些都不符合绿色化学理念。因此，研究在无溶剂催化下完成无毒无害的快速反应是很有必要的。36579

本论文以苯乙酮为测试底物，与毒性小、价格便宜的氯代试剂三氯异氰尿酸（TCCA）反应，并使用苄基三乙基氯化铵（TEBAC）作为催化剂，优化反应条件，尝试发展绿色、高效的氯代化合物合成路线。通过优化的实验条件是：苯乙酮的量为1.20 g，三氯异氰尿酸的量为1.55 g，苄基三乙基氯化铵的用量为0.30 g，在室温条件分3次加入下搅拌反应30 min，α，α-二氯代苯乙酮的产量为1.76 g，产率为92.1%。在优化条件的基础上，将苯乙酮类化合物作为测试底物时发现，二氯代物的产率在73.2% ~ 93.5%之间，产率相对较高的是苯乙酮（92.1%），对甲基苯乙酮（93.5%）。

The study of synthesis of lachrymatory compound
Abstract: Since the traditional chemical industry brings more and more serious the environment pollution, people realize the importance of protecting the environment. So people put forward the concept of green chemistry. In recent years, people are paying more and more attention to environmental protection, so it is necessary to carry out green chemistry. Chlorination of phenyl ethyl ketone compounds are important intermediates in organic synthesis, although there are many methods to synthesize these compounds, these methods have the following disadvantages, such as long reaction time,using toxic reaction reagent,post-processing of trouble and so on, which do not conform to the concept of green chemistry. Therefore, it is necessary to research done in solvent-free catalytic non-toxic harmless rapid response.
This thesis is trying to optimize the reaction condition that using acetophenone as the substrate reacted with trichloroisocyanuric acid, which is cheap and low toxicity under using triethylbenzylammonium chloride as catalyst, then trying to develop the green and efficient synthetic route of chloride. The optimized experiment condition was: at the temperature, acetophenone, which quality was 1.20 g and trichloroisocyanuric acid, which quality was 1.55 g were mixtured with triethylbenzylammonium chloride, which quality was 0.30 g, to stir for 30 min. Besides, triethylbenzylammonium chloride was pointed three times to join. The yield of α，α-dichloro phenylethanone was 92.1%. On the basis of the optimized conditions, when acetophenones were used as the substrate, the yield of chlorination were between 73.2% and 93.5%. Acetophenone and p-methylacetophenone were in high yield (92.1%, 93.5%).
