Modified resin catalyst and application thereof in preparation of tert-dodecyl mercaptan

The invention provides a modified resin catalyst and application thereof in preparation of tert-dodecyl mercaptan, and belongs to the field of preparation of fine chemicals. Resin is activated and modified by adopting a surfactant and triisobutylene to obtain a modified resin catalyst, and the modified resin catalyst is used for catalyzing triisobutylene and hydrogen sulfide to react to prepare tert-dodecyl mercaptan. The modified resin catalyst is excellent in activity and long in service life, the problem that an ideal effect can be achieved only at an extremely low temperature when tert-dodecyl mercaptan is prepared from triisobutylene and hydrogen sulfide is solved, meanwhile, the problem that an existing catalytic system is fast in inactivation is solved, and therefore the modified resin catalyst has obvious economic advantages and is suitable for industrial production. The method is especially suitable for large-scale production. 本发明提出了一种改性树脂催化剂及其在制备叔十二烷基硫醇中的应用，属于精细化工品制备领域。本发明采用表面活性剂和三异丁烯对树脂进行活化改性，得到改性树
