Carbon disulfide
Carbon disulfide is a colorless, volatile, highly flammable liquid with formula CS₂. It is used as an industrial solvent and chemical feedstock.
Molecular geometry: The three-dimensional arrangement of atoms in a molecule, shaped by bonding and electron interactions. CS₂ has a linear S=C=S structure, with sulfur atoms on opposite sides of carbon.
Viscose: A regenerated-cellulose fiber or material made by dissolving cellulose and re-forming it from solution. Carbon disulfide converts alkali cellulose into cellulose xanthate during viscose production.
Carbon disulfide poisoning: Illness caused by exposure to carbon disulfide, especially through inhalation or prolonged skin contact. Repeated exposure can damage the nervous and cardiovascular systems, particularly in industrial settings.
William Christopher Zeise: A Danish chemist known for foundational work in organometallic chemistry and for preparing carbon disulfide in the early nineteenth century. Zeise reported an early preparation of CS₂ from sulfur and charcoal in 1813.
Carbon dioxide: A colorless gas with formula CO₂, produced by respiration, combustion, and other processes. Both molecules are linear, but replacing oxygen with sulfur changes volatility, reactivity, and flammability.
Carbon–sulfur bond: A chemical bond between carbon and sulfur atoms, found in many organic and inorganic compounds. The C=S bonds give the molecule its linear structure and characteristic chemical reactivity.
Cellophane: A thin, transparent film made from regenerated cellulose. The viscose process, which uses carbon disulfide, can produce cellophane as well as textile fibers.
Occupational exposure limit: A regulatory or advisory concentration limit for a hazardous substance in workplace air. Workplace limits constrain inhalation exposure during production and use of CS₂.
Cellulose: A structural polysaccharide made of glucose units that forms the main component of plant cell walls. The search for soluble cellulose derivatives created a major industrial use for carbon disulfide.
Carbon diselenide: A linear compound with formula CSe₂, containing carbon double-bonded to two selenium atoms. It is the heavier selenium analogue of CS₂, with different stability and physical properties.
