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。
Dodecyl mercaptan is mainly used for the preparation of styrene-butadiene rubber, ABS resin and nitrile rubber, and the relative molecular weight of its polymerization is regulated. The properties, applications and synthesis methods of n-dodecyl mercaptan were briefly introduced. Based on the literature, the effects of n-dodecyl alcohol, 1-dodecene and 1-halo dodecane as the raw materials, Urea, hydrogen sulfide and other sulfur compounds Synthesis of n-dodecyl mercaptan method, and the synthesis of the route were analyzed and compared, pointed out that the synthesis of n-dodecanol hydrogen sulfide catalytic route in the preferred method is a better method . The domestic synthesis of n-dodecanethiol is proposed.
