硫氰酸苄酯的合成

Synthesis of Benzyl Thiocyanate

在乙醇为溶剂中 ,由苄基氯和硫氰酸钾合成了硫氰酸苄酯。合成的优化条件为苄基氯和硫氰酸钾的摩尔比为 0 .0 2 5∶ 0 .0 5 0 ,溶剂 2 0 ml,反应温度 80℃下反应 5 .0 h,产品收率达 97%

The benzy1 thiocyanate was synthesised by the reaction of benzy1 chloride and potassium thiocyanate in ethanol as solvent. The optimum conditions for synthesis are mol. ratio of PhCH 2Cl∶KSCN to be 0.025∶0.050,solvent 20 ml ,the reaction times 5.0 h,reaction temperature 80 ℃,the yield was 97%.
