![]() ![]() Thermally stable with low viscosity, DMDS (Dimethyl Disulfide) is suitable for gas- or liquid-phase injection.ĭMDS (Dimethyl Disulfide) begins to decompose to H2S at low temperatures, so the risks of reducing the metal oxides prior to sulfiding are eliminated. Thiophene and DMDS (Dimethyl Disulfide) are blended with combustible hydrocarbon fuel gas to impart a gassy odor to the fuel gas.ĭMDS (Dimethyl Disulfide) is also used as a flavor and fragrance intermediate, which enriches the aroma and flavor of certain consumer products.ĭMDS (Dimethyl Disulfide) is a sulfiding agent, which is used along with a reducing agent such as hydrogen, to transform metal oxide species to a metallic sulfide crystalline phase in situ for hydrotreating catalysts.ĭMDS (Dimethyl Disulfide) can also be used as a passivation agent to reduce the layer of coke that forms within furnaces and improve the run length, yield and life of furnaces.Ĭompared to other sulfiding agents, DMDS (Dimethyl Disulfide) has the highest sulfur content, which reduces the amount of product required for converting oxides to active metal sulfides. The H2S reacts with the metal oxides on the catalyst, converting them to the active metal sulfide form.ĭMDS (Dimethyl Disulfide) also works as an effective product for operators in the petrochemicals industry who must protect their steam-cracking coils against the formation of coke and carbon monoxide.ĭMDS (Dimethyl Disulfide) is utilized in the preparation of 4-(methylthio)phenol which is used in the production of various pesticides.ĭMDS (Dimethyl Disulfide) and chlorine are reacted with borontrifluoride phenoxide to produce 4-(methylthio)phenol. Once injected to a hydrotreater or hydrocracker, DMDS (Dimethyl Disulfide) decomposes to form H2S. Most refineries utilize DMDS (Dimethyl Disulfide) 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). ![]() In this capacity, DMDS (Dimethyl Disulfide) is an important alternative in replacing methyl bromide, which is being phased out, however less effective than the former.ĭMDS (Dimethyl Disulfide) is used to alpha substitute 2-methylfuran-acrolein to produce a food stuff used in concentrations from 0.02 ppm up to 50 ppm.ĭMDS (Dimethyl Disulfide) is a stable pale yellow liquid which works as an effective product for sulfiding hydroprocessing catalysts because of its high sulfur content and low decomposition temperature. Industrially, DMDS (Dimethyl Disulfide) is used in oil refineries as a sulfiding agent.ĭMDS (Dimethyl Disulfide) is also an effective soil fumigant in agriculture 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 (CH3S(O)SCH3).ĭMDS (Dimethyl Disulfide) is used as a food additive in: These flies are attracted to the odor resembling that of fetid meat, and thus help pollinate this plant.ĭMDS (Dimethyl Disulfide) can be produced by the oxidation of methanethiol, e.g. DMDS (Dimethyl Disulfide) is an organic chemical compound with the molecular formula CH3SSCH3 which is the simplest disulfide.ĭMDS (Dimethyl Disulfide) is a flammable liquid with an unpleasant, garlic-like odor.ĭMDS (Dimethyl Disulfide) appears as a colorless oily liquidĭMDS (Dimethyl Disulfide) has a garlic-like odor.ĭMDS (Dimethyl Disulfide) is denser than waterĭMDS (Dimethyl Disulfide) is slightly soluble in water.ĭMDS (Dimethyl Disulfide)'s vapors heavier than air.ĭMDS (Dimethyl Disulfide) is an organic disulfide that is methane in which one of the hydrogens has been replaced by a methyldisulfanyl group.ĭMDS (Dimethyl Disulfide) has a role as a xenobiotic metabolite.ĭMDS (Dimethyl Disulfide) is a natural product found in Allium vineale, Psidium guajava, and other organisms with data available.ĭMDS (Dimethyl Disulfide) is a widespread natural odoriferous compound emitted from many sources such as bacteria, fungi, plants and animals.ĭMDS (Dimethyl Disulfide) is an oxidation product of methanethiol in air.Īlong 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 (Helicodiceros muscivorus). ![]()
