Description

General description

Carbon disulfide is a widely used solvent in the production of rayon fibers, carbon tetrachloride, pesticides, vulcanizers, cellophane, adhesives, and other chemicals. It is also used as a starting material in the synthesis of various sulfur-containing derivatives.

Application

Carbon disulfide can be used as a solvent:

• To synthesize hydroxynaphthyl ketones via Friedel-Crafts acylation and demethylation.
• In the regioselective bromination of binaphthols.
