Synthesis method

Sodium pentamethylene dithiocarbamate is prepared from the reaction of hexahydropyridine, sodium carbonate and carbon disulfide, and then treated with sulfur monochloride to obtain bispentpentane tetrasulfide Methylenethiuram.


This product is a thiuram vulcanization accelerator, which can be used in natural rubber, diene synthetic rubber, butyl rubber, EPDM rubber, chlorosulfonated polyethylene and latex. Heating can decompose free sulfur and can also be used as a vulcanizing agent. The effective sulfur content is 25% of its weight. When used as a vulcanizing agent, this product is relatively safe at the operating temperature. The vulcanized rubber has excellent heat resistance and aging resistance. This product is easily dispersed in dry rubber and water. Does not pollute. Generally used to manufacture heat-resistant products, cables, etc.
