koltvísýringeins

Koltvísýringur, also known as carbon disulfide, is a colorless, volatile, and flammable liquid with the chemical formula CS2. It possesses a distinct, unpleasant odor, often described as resembling rotten eggs, although pure carbon disulfide is nearly odorless. This compound is miscible with many organic solvents but has low solubility in water.

Industrially, carbon disulfide is produced by the reaction of methane or natural gas with sulfur vapor at high temperatures. Historically, it was a significant solvent for materials like rubber, sulfur, and phosphorus, and it played a role in the production of rayon and cellophane. Currently, its primary uses include the synthesis of carbon tetrachloride and various agricultural chemicals, such as pesticides and herbicides.

Carbon disulfide is highly toxic and poses significant health risks through inhalation, skin absorption, and ingestion. Exposure can lead to a range of symptoms affecting the central nervous system, cardiovascular system, and gastrointestinal tract. Due to its flammability and toxicity, handling carbon disulfide requires strict safety precautions, including adequate ventilation and personal protective equipment. It is also an environmental concern, with potential impacts on ecosystems if released into the environment.
