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.[57] C2S may undergo hydrolysis catalyzed by nanosized titania and zirconia to form CO2 and H2S.[77]

Application

Carbon disulfide may be used in the xanthogenation of cellulose[67] and in the synthesis of poly(ethylene trithiocarbonate)[68] and dithiocarbamates.[76] It can also generate 1,3-dithiolium carbenes via cycloaddition with acetylenes.[78]
