Description and Uses
For many years, carbon disulfide was manufactured by the reaction of charcoal with sulfur vapor at temperatures of 750– 1000 C, but by the mid-twentieth century, especially in the United States, the process was superseded by the reaction of natural gas (principally methane) with sulfur.
Carbon disulfide is used in the manufacture of regenerated cellulose rayon, cellophane, soil disinfectants, and electronicvacuum tubes. Other major uses are in theproduction of carbon tetrachloride, xanthates,thiocyanates, plywood adhesives, and rubberaccessories. It is also used as a solvent and asan eluant for organics adsorbed on charcoalin air analysis.
