Dimethyl disulfide is used as solvent and pesticide intermediate, fuel and lubricant additive, coking inhibitor in ethylene cracking furnace and refining unit, etc.
Dimethyl disulfide is used as a solvent and pesticide intermediate, and is also the main raw material for methylsulfonyl chloride and methylsulfonic acid products.
Dimethyl disulfide, also known as dimethyl disulfide, is used to synthesize the intermediates of organophosphorus pesticides fenthion and fenthionate, p-methylthio-m-cresol, and the intermediates of thiopropyl and p-methyl Thiophenol is also used as a purifying agent for solvents and catalysts.
Dimethyl disulfide is used as solvent, catalyst passivator, pesticide intermediate, coking inhibitor, etc. Dimethyl disulfide reacts with cresol to form 2-methyl-4-hydroxyanisole sulfide, which is then condensed with O,O-dimethylphosphoryl sulfide chloride in an alkaline medium to obtain fenthion. This is a highly efficient and low-toxic organophosphorus insecticide with excellent control effects on rice borers, soybean borers and gadfly larvae. It can also be used as veterinary medicine to eliminate cattle fly maggots and cattle ticks.
