WebDMDS injection begins as the temperature approaches 400°F, with the reactor held in a range of 400–420°F until H2S breakthrough occurs. Breakthrough is indicated when the H2S level of the recycle gas … DMDS is used to prepare catalysts for hydrodesulfurization, because of its high sulfur content and low decomposition temperature. Refineries utilize DMDS instead of other sulfur spiking agents for catalyst sulfiding because it has more sulfur per pound than dimethyl sulfide (DMS) or di-tertiary-butyl polysulfide (TBPS). [11] See more Dimethyl disulfide (DMDS) is an organic chemical compound with the molecular formula CH3SSCH3. It is a flammable liquid with an unpleasant, garlic-like odor. The compound is colorless although impure samples … See more Important reactions include chlorination giving methanesulfenyl chloride (CH3SCl), methanesulfinyl chloride (CH3S(O)Cl), and methanesulfonyl chloride (CH3SO2Cl) as well as oxidation with hydrogen peroxide or peracetic acid giving the thiosulfinate methyl methanethiosulfinate … See more Dimethyl disulfide is a widespread in nature. It emitted by bacteria, fungi, plants, and animals. Along with dimethyl sulfide and dimethyl trisulfide it has been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum See more DMDS is used as a food additive in onion, garlic, cheese, meats, soups, savory flavors, and fruit flavors. Industrially, DMDS is used in oil refineries as a sulfiding agent. DMDS is also an effective soil fumigant in agriculture, registered in many states in the … See more
