China and India are the leading exporters of carbon disulfide, accounting for the majority of global shipments, while the United States, Germany, and South Korea represent the largest importers. These importing countries primarily source carbon disulfide for viscose rayon production and chemical synthesis. Global carbon disulfide trade volumes have remained relatively stable over the past three years, with modest regional shifts in sourcing—particularly increased imports by South Korea amid tightening domestic environmental regulations—and steady demand underpinning carbon disulfide prices.
Carbon disulfide is a clear, volatile, colorless to faintly yellow liquid with a strong, chloroform-like odor. It is a nonpolar, organosulfur compound classified as a chemical intermediate and solvent. With a boiling point of 46.3 °C and a melting point of −111.6 °C, it is highly flammable and readily evaporates at ambient temperatures. Its primary industrial use is in the production of rayon and cellophane via the xanthation of cellulose; it also serves as a key precursor in the synthesis of carbon tetrachloride, thiocarbamate pesticides, and rubber chemicals such as accelerators and vulcanization agents. Typical application areas include synthetic fibers, agrochemicals, and elastomer processing.
Manufacture of rayon viscose fibers and cellophane film; solvent for lipids, sulfur, rubber, phosphorus, oils, resins, and waxes; insecticide.
Carbon disulfide (carbon bisulfide; CS2; CASRN 75-15-0), in its pure form is a colorless liquid that evaporates readily at room temperature, with a sweet aromatic odor similar to that of chloroform. In its impure commercial and reagent form, however, carbon disulfide is a yellowish liquid with a foulsmelling odor. It can be detected by odor at about 1 ppm but the sense of smell fatigues rapidly and, therefore, odor does not serve as a good warning property. It has a vapor pressure of 297mmHg and solubility in water by weight of 0.3% at 20 °C (68 °F). Once carbon disulfide is in the air it will break down into simpler substances within a few days after release (OEHHA, 2001).
