Di-tert-butyl Polysulfide

Product Overview

Di-tert-butyl polysulfide represents a advanced class of organic sulfur compounds designed for high-performance industrial applications. As a superior alternative to traditional dimethyl disulfide, this compound offers enhanced safety profiles and operational efficiency. It is specifically engineered to function as a pre-sulfiding agent for hydrogenation catalysts and as an anti-coking additive in ethylene cracking units. Our manufacturing process ensures exceptional purity, making it comparable to leading international standards such as Chevron Phillips TBPS 454.

Technical Specifications
