Recently, Junyuan Petroleum Group has developed DTBPS (Di-tert-butyl Polysulfide) environmentally friendly and safe vulcanizing agent, which has the characteristics of no odor, low odor, high flash point, strong safety performance, and significant intrinsic safety characteristics. It has become an ideal green and reliable substitute for traditional dimethyl disulfide (DMDS) vulcanizing agent products.
It is understood that dimethyl disulfide is widely used as a pre sulfurization catalyst, sulfur injection for sulfur supplementation, and coking inhibitor for ethylene cracking in industry. Due to its good oil solubility and high sulfur content, it is widely used. However, it has strong irritancy, suffocating odor, toxicity, high risk factor, and high cost, which brings enormous pressure to the hydrogenation industry.
Based on this, Junyuan Petroleum Group has developed DTBPS (Di-tert-butyl Polysulfide) environmentally friendly and safe vulcanizing agent through collaborative innovation between industry, academia, and research. The flash point of this vulcanizing agent is over 100 ℃, which belongs to non flammable materials and greatly reduces potential production, transportation, and storage risks. Moreover, the decomposition temperature is low, and it can be injected into the system at around 160 ℃ to participate in the vulcanization reaction, increasing the activity of the catalyst and shortening the vulcanization time.
