Can be miscible with water, ethanol, acetone, acetaldehyde, pyridine, ethyl acetate, dibutyl phthalate, dioxane, and aromatic compounds, but insoluble in fatty hydrocarbon compounds other than acetylene. It has strong hygroscopicity and can absorb 70% of its own weight of moisture from the air at a relative humidity of 60% at 20 ℃. This product is a weak oxidant and does not contain water. Dimethyl sulfoxide is non corrosive to metals. When containing water, it affects iron; Copper and other metals are corrosive, but they do not corrode aluminum. Stable to alkali. Heating in the presence of acid will produce small amounts of methyl mercaptan, formaldehyde, and dimethyl sulfide; Compounds such as methanesulfonic acid. It decomposes at high temperatures and reacts violently with chlorine, burning in the air and emitting a light blue flame.
