Di-Tert-Butyl Polysulfide/TBPS CAS 68937-96-2

[Typical Properties]

With certain stability and fluidity, but is prone to volatilization at high temperatures. 

[Specification]

[Usage]

*TBPS is an ideal substitute for the widely used dimethyl disulfide, comparable to similar foreign products. It is widely used as a pre sulfurizing agent for hydrogenation catalysts in hydrogenation units and as an anti coking agent for ethylene cracking units. The most prominent features of this compound are high sulfur content, high purity of organic polysulfides, no impurities or metal ions, and it will not cause catalyst poisoning when used as a pre sulfurizing agent; The molecular weight distribution is wide, and the decomposition temperature range during sulfurization is wide. When sulfurizing the catalyst, it can avoid the concentrated heat release of the catalyst, which will not cause the catalyst to sinter and is convenient for sulfurization operation.

*TBPS is widely used in the fields of oil refining, petro- chemical, coal chemical, fine chemical a and other fields for hydrogenation catalyst presulfidation, sulfur supplementation and sulfur injection; it has achieved good environmental protection and safety pr oduction effects and economic benefits.
