绿色肟化反应的综合实验设计OA
Design on the Comprehensive Experiment for the Green Oximation Reaction
根据科研成果,针对传统肟化反应中存在的问题设计了一种绿色肟化反应的综合实验,对所用的碱和反应装置进行了改进.首先利用湿法研磨制备可循环利用的高活性纳米碳酸钾,通过激光粒径分布仪,扫描电子显微镜(SEM),CO2-程序升温实验(CO2-TPD)进行表征;然后利用纳米碳酸钾为碱合成α-羟亚胺芳基丙酸酯,通过串联装置实现亚硝酸酯的制备与苄基丙二酸二乙酯的肟化反应同步进行.实验避免了醇钠不能回收、腐蚀设备的缺点,解决了亚硝酸酯易挥发造成的贮存、转运困难、容易污染环境的问题.该综合实验利于学生建立环境友好的绿色化学的理念,提高学生综合能力和素质,培养科研创新思维能力.
According to some research achievements,a green oximation comprehensive experiment was designed to overcome the shortcomings of the traditional oximation reaction,and the base and reaction equipment were improved.Recyclable nano-K2CO3 was prepared firstly by ultrafine wet milling and characterized by the laser particle size analyzer,scanning electronic microscopy(SEM),and CO2-TPD.The synthesis of ethyl α-(hydroxyimino)benzenepropanoate was performed using nano-K2CO3 as the base.The preparation of ethyl nitrite and oximation of diethyl benzylmalonate were carried out simultaneously by series devices.The experiment avoids the shortcomings of sodium alkoxides that cannot be recovered and corrodes equipment,and solves the problems of storage and transportation difficulties and easy environmental pollution of volatile nitrite.This comprehensive experiment is beneficial for students to learn the idea of environment-friendly green chemistry,improve the students'comprehensive ability and quality,and cultivate their scientific research innovation thinking ability.
