| 摘 要： | 用电导法分别测定了三乙基苄基氯化铵合成反应在乙醇、正戊醇、１，２－二氯乙烷三种溶剂中的反应进程，此反应在三种介质均为二级反应；求出了不同温度下的反应速度常数、反应活化能、指前因子以及活化熵变；１，２－二氯乙烷是非质子性溶剂，对三乙基苄基氯化铵合成这类双分子亲核反应有利。乙醇溶剂的反应速度随温度升高而明显加快。

| Abstract: | The relation concentration and time of system benzyltrimethylammonium chloride synthetic reaction in ethanol penanol and 1,2 dichlorine ethane respectively is determinated by electricl conductance in this paper.The reaction is second order in three solvents and activation energy,factor before exponent,activation entropy,reaction speed constant in different temperature,solvents are given. 1,2 dichlorine ethane is no proton solvent and for belong to S N2 reaction of benzyltrimethylammonium chloride synthesize is beneficially.The reaction speed accelerate evidently with temperature rise when ethanol as solvent. |
