Synthetic method of 1,1'-dicaprolactam disulfide

The invention discloses a synthetic method of 1,1'-dicaprolactam disulfide. Caprolactam is used as an initiator, and sulfur monochloride and caprolactam inorganic salt are used as raw materials. Sulfur monochloride firstly reacts with caprolactam to form 1,1'-dicaprolactam disulfide and acid; caprolactam inorganic salt is continuously converted to caprolactam under the action of the acid formed bythe reaction; and caprolactam continuously reacts with sulfur monochloride to form 1,1'-dicaprolactam disulfide. According to the method, there is no need to add other types of acid-binding agents, and the raw material caprolactam can be synthesized by itself in the reaction process. The production technology is simple, has strong operationality and simple post-treatment, and has industrial application value. The product is white solid powder in the appearance, and the yield is 88% and above, the purity is 99% and above. The product meets the use requirements.

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.
