Dimethyl sulfide Usage And Synthesis
Chemical PropertiesClear colorless liquid
DefinitionChEBI: A methyl sulfide in which the sulfur atom is substituted by two methyl groups. It is produced naturally by some marine algae.
UsesSulfiding agent.
General DescriptionA clear colorless to straw colored liquid with a disagreeable odor. Flash point less than 0°F. Less dense than water and slightly soluble in water. Vapors are heavier than air.
Air & Water ReactionsHighly flammable. Slightly soluble in water.
Reactivity ProfileOrganosulfides, such as Dimethyl sulfide, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Dimethyl sulfide rapidly decomposes dibenzoyl peroxide explosively in the absence of solvent, [J. Org. Chem., 1972, 37, 2885]. The sulfide also decomposes xenon difluoride explosively at ambient temps, [J, Chem Soc., 1984, 2827]. Interaction of Dimethyl sulfide and oxygen is explosive at 210°C and above, [Atmos. Environ., 1967, 1, 491-497]. A delayed explosion occurred in a system containing nitric acid, Dimethyl sulfide, and 1, 4-dioxane, even with cooling with liquid nitrogen, [Chem. Abs., 1972, 76, 13515].
Health HazardInhalation causes moderate irritation of upper respiratory system. Contact of liquid with eyes causes moderate irritation. Repeated contact with skin may extract oils and result in irritation. Ingestion causes nausea and irritation of mouth and stomach.
Safety ProfilePoison by inhalation. Moderately toxic by ingestion. A skin and severe eye irritant. A very dangerous fire hazard when exposed to heat or flame. Explosive in the form of vapor when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of SOx and may explode. See also SULFIDES.
Purification MethodsPurify dimethyl sulfide via the Hg(II) chloride complex by dissolving 1 mole of Hg(II)Cl2 in 1250mL of EtOH and slowly adding the boiling alcoholic solution of Me2S to give the right ratio for 2(CH3)2S.3HgCl2. After recrystallisation of the complex to constant melting point, 500g of complex is heated with 250mL conc HCl in 750mL of water. The sulfide is separated, washed with water, and dried with CaCl2 and CaSO4. Finally, it is distilled under reduced pressure from sodium. Precautions should be taken (efficient fume hood) because of its very UNPLEASANT ODOUR.[Beilstein 1 IV 1275.]
