摘　　要：正十二碳硫醇主要用于丁苯橡胶、ABS树脂和丁腈橡胶的制备,对其聚合相对分子量进行调节。简单介绍了正十二碳硫醇的性质、用途及合成方法,以文献为基础,总结了以正十二醇、1-十二烯、1-卤代十二烷等为原料,分别与硫脲、硫化氢等含硫化合物反应合成正十二碳硫醇的方法,并对合成路线进行分析、比较,指出正十二醇为原料的合成路线中硫化氢催化取代法是一个较好的方法。对国内正十二碳硫醇合成研究提出了建议。n- dodecyl mereaptan is mainly used for the preparation of styrene -butadiene rubber （SBS）, acrylonitrile -butadiene -styrene resin （ ABS resin）, acrylonitrile - butadiene rubber, and adjusting their formula weight. The properties, application, and synthetic method of n - dodecyl mercaptan are briefly introduced. On the basis of literature, the synthetic methods of n - dodecyl mercaptan are summarized which use 1 - dodecanol, 1 - dode- cylene and n -dodecyl chloride as raw materials, and then make them react with sulfocompound such as sulfourea, hydrogen sulfide respectively. The analysis and comparison of these synthetic processes is carried out. It is indicated that the method is best, which uses 1 -dodecanol as raw material, and in the process, hydrogen sulfide catalytic substitution is applied. The suggestion on the study on the synthesis of n - dodecyl mercaptan is proposed.
