说明

General description

Carbon disulfide is a highly volatile, flammable liquid with low ignition temperature. It is an important raw material for preparing viscose rayon and cellophane film. C₂S may undergo hydrolysis catalyzed by nanosized titania and zirconia to form CO₂ and H₂S.

Application

Carbon disulfide may be used in the xanthogenation of cellulose and in the synthesis of poly(ethylene trithiocarbonate) and dithiocarbamates. It can also generate 1,3-dithiolium carbenes via cycloaddition with acetylenes.
