Benzyl mercaptan
化合物简介
Benzyl mercaptan is an organosulfur compound with the formula C6H5CH2SH. It is a common laboratory alkylthiol and occurs in trace amounts naturally. Condensed tannins can undergo acid-catalyzed cleavage in the presence of the nucleophilic benzyl mercaptan. Benzyl mercaptan has been identified in boxwood (Buxus sempervirens L.) and is known to contribute to the smoky aroma of certain wines. It also occurs naturally in coffee.

生产方法及用途
生产方法
以S-苄基异硫脲盐酸盐与10%氢氧化钠溶液投入反应器中,用直火加热回流2h,进行水解。然后冷却,再用稀硫酸酸化,用乙醚萃取,萃取液用无水硫酸钠干燥,然后滤出干燥剂,回收乙醚,剩余物经减压蒸馏,收集98~108℃(2.6664kPa)的馏分,即得成品。 用于香精制造。
