Use

Organosulfides, 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].
