摘要
研究了以烯丙基溴和硫脲为原料 ,在相转移催化剂四丁基溴化铵的作用下 ,以水作溶剂 ,制得S 烯丙基异硫脲盐 ,并在氢氧化钠水溶液中水解 ,酸化 ,制得了重要的含硫香料烯丙硫醇。
Propene-1-thiol was prepared by hydrolyzing S-allyl-iso-thiourea bromide in aqueous solution of sodium hydroxide and acidifying with dilute sulfuric acid.S-Allyl-iso-thiourea bromide could be synthesized by the reaction of allyl bromide with thiourea in aqueous solution of tetrabutyl ammonium bromide.The content and structure of 2-propene-1-thiol were confirmed by GC and IR.
