Method for synthesizing rubber vulcanizer DTDC

The invention discloses a method for synthesizing a rubber vulcanizer DTDC. The method comprises the step of subjecting caprolactam and sulfur monochloride, which serve as raw materials, to a reaction by taking triethylenediamine as an acid binding agent, thereby obtaining the DTDC. According to the method, the triethylenediamine simultaneously serves as a catalyst and the acid binding agent and can be recycled, so that the disadvantage of wasting of the caprolactam is effectively overcome, meanwhile, the reaction time is greatly shortened, and the production efficiency is increased obviously.

Preparation method of vulcanizer 1,1'-dithiodicaprolactam

The invention belongs to the technical field of rubber synthesis, relates to additives, used to increase the wear resistance and corrosion resistance of rubber, for rubber synthesis, and particularlyto a preparation method of vulcanizer 1,1'-dithiodicaprolactam. The preparation method uses organic amine to replace caprolactam to serve as the acid-binding agent, the organic amine can be recycled,and the defects that the caprolactam cannot be recycled, and great waste is caused are overcome. Compared with the prior art, the preparation method has the advantages that the organic amine used as the acid-binding agent can be recycled after the reaction, cost is lowered, and environments are protected.
