摘　　要：介绍了以无水三氯化铝络合物为催化剂,十二烯和硫化氢直接加成法生产叔十二烷基硫醇的工业试验工艺。该合成工艺主要由催化剂制备、十二烯原料提纯、加成反应和反应产物分离4个单元组成,经分离提纯制得质量分数大于98.5%的叔十二烷基硫醇产品,单程总收率不低于70%。The process industrial synthsis of tert-dodecyl mercaptan from dodecylene and hydrogen sulfide with aluminium trichloride as catalyst was introduced, which consists of four units including the preparation of catalyst, purification of raw dodecylene,additive reaction and separation of reaction product.The yield of tert-dodecyl mercaptan can be higher than 70%. By the separation and purification of addition product, the product concentration of tert-dodecylmercaptan can be higher than 98.5 wt%.
