Application:
Dimethyl Disulfide (DMDS) (CAS: 624-92-0) is an organic disulfide that is methane in which one of the hydrogens has been replaced by a methyldisulfanyl group, it has a diffuse intense onion odor. Although many find its odor objectionable at high concentrations, when diluted, its aroma has also been described as pleasant. Dimethyl Disulfide is often used in combination with other flavor compounds in food products, including baked goods, cheese, frozen dairy products, meat products, soups, savory flavors, fruit flavors, soft candy, gelatin, puddings, and both alcoholic and nonalcoholic beverages. It finds application in artificial flavoring agent and a corrosion inhibitor. Sulfur Compounds. Flavor and Fragrance Chemical Compounds. Industrially, Dimethyl Disulfide is also used as a sulfiding agent to catalyze reactions in oil refineries and other industries. Dimethyl Disulfide is widely used in organic synthesis and pesticide intermediates. Used as a solvent, a passivator for a catalyst. Used as a fuel and lubricant additive. It is also the main raw material for methanesulfonyl chloride and methanesulfonic acid products, as well as catalyst vulcanization and passivating agent. Preparation Dimethyl Disulfide can be prepared by the reaction between imethyl sulfate and sodium sulfide. under stirring, sulfur powder was added into sodium sulfide solution. The above reaction system was heated Up to 80-90℃, after reaction for 1 h, cooled to about 30℃. Dimethyl Sulfate was dropped into the reaction system and the reaction was continued for 2h. Then, distillation, stratification, separating waste alkali liquor, then through distillation and final products are prepared. In industry, Dimethyl sulfate method is adopted to synthesize dimethyl disulfide.Sufficient Capacity: Sufficient facilities and technicians
