Carbon disulfide is primarily used in the production of viscose rayon and cellophane, where it serves as a solvent in the xanthation process to convert cellulose into a soluble compound. In agriculture, it is employed as a soil fumigant to control nematodes and other pests, enhancing crop yields. The chemical is also utilized in the manufacture of carbon tetrachloride and other sulfur-containing compounds. In the rubber industry, it acts as a vulcanizing agent to improve the elasticity and strength of rubber products. Additionally, carbon disulfide is used in the production of flotation agents for mineral processing, aiding in the separation of valuable ores from waste materials.
