摘要
氯化胆碱具有自催化作用。在三甲胺和氯乙醇反应时加人3%(mol)氯化胆碱,50℃下,3h 后的转化率可达100%。不加催化剂或加[(CH_3)_4N]^+OH^-、NaOH 时的转化率分别为90.8%,91.9%及94.2%。
An autocatalysis of choline chloride(CC)in the reaction between ethylene chlorohydrin(EC)and trimethylamine(TMA vas observed.When the molar ratio of CC:EC:TMA is 0.03:1:1.03,the conversion of EC to CC at50℃,after 3h,is 100%.In comparison with it,theconversions,without and with two kinds ofcatalysts(quaternary ammonium hydroxideand sodium hydroxide)are 90.8%,91.9%,and94.2% respectively.
