研究了以苄基三乙基氯化铵为相转移催化剂制备乙酸苄酯,得出了最佳操作条件,使反应收率达86%。
This article studies benzyl - triethyl ammonium chloride as catalyst of phase - transfer to prepare for phenyl acetate. Get the best operating condition and get the yield of 86%.
实验结果表明:本体系中相转移催化剂的催化效率是苄基三乙基氯化铵大于四丁基溴化铵和四乙基溴化铵;
The results show that catalytic efficiency of the phase transfer catalyst BETAC is higher than TBAB, and TBAB is nearly as efficient as TEBA.
研究出用价廉、易得,能够方便自产的间—苯氧基苄基三乙基氯化铵作为相转移催化剂,获得了较好的结果。
Authors have obtained by using m-phenoxybenzyltriethylammonium chloride as the phase transfer catalyst which is cheap, available and self—productive. We hare achieved better results.
但是电解时,支持电解质四乙基氯化铵也发生了部分分解,生成了氯乙烷和乙胺,这还需在以后的实验中进一步选择。
Meanwhile the supporting electrolyte, i. e. tetraethylammonium is decomposed to chloroethane and ethylamine, so the supporting electrolyte should be improved in future.
