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.
