Dimethyl disulfide: chemical properties: light yellow transparent liquid. There is a stench. Insoluble in water, miscible with ethanol, ether and acetic acid.
Uses: Used as solvents and pesticide intermediates, fuel and lubricant additives, coking inhibitors for ethylene cracking furnaces and refining units, etc.
Used as solvent and pesticide intermediate, and also the main raw material of methylsulfonyl chloride and methylsulfonic acid products.
GB 2760–1996 stipulates the permitted food spices.
Dimethyl disulfide, also known as dimethyl disulfide, is used in the synthesis of organophosphorus pesticides fenthion and fenthionate as intermediates p-methylthio-m-cresol and thiopropyl as an intermediate p-methylthio Phenol is also used as a purifying agent for solvents and catalysts.
Used as solvents, catalyst passivants, pesticide intermediates, coking inhibitors, etc. Dimethyldisulfide reacts with cresol to form 2-methyl-4-hydroxyanisole sulfide, which is then condensed with O,O-dimethylphosphorus sulfide chloride in an alkaline Chemicalbook 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.
Production method: Produced by the reaction of methylmagnesium iodide and disulfide dichloride. It is formed by the reaction of disodium disulfide and sodium methyl sulfate. It is produced by reacting methyl bromide and sodium thiosulfate to obtain sodium methyl thiosulfate, which is then heated.
