Dimethyl sulfide
Properties:
– Appearance: colorless liquid with a strong peculiar odor.
– SOLUBILITY: Miscible with ethanol, ether and many organic solvents.
USES:
– Industrial application: dimethyl sulfide is widely used as a solvent in organic synthesis reactions, especially in sulfurization reactions and thioaddition reactions play an important role.
Method of Preparation:
– Dimethyl sulfide can be prepared by the direct reaction of ethanol and sulfur. The reaction is usually carried out under acidic conditions and requires heating.
– It can also be made by adding sodium sulfide to two methyl bromides (e.g., bromomethane).
