What Is Carbon Disulfide?
Carbon disulfide, a volatile liquid with the chemical formula CS2, is used extensively as a solvent and raw material in organic synthesis. Found in trace amounts in coal and crude oil, it is notable for its use in the production of cellophane, and rayon, and as a vulcanization accelerator for rubber.
Uses of Carbon Disulfide
Its utility spans from being a solvent for phosphorus, sulfur, and selenium, to being used in the purification of single-walled carbon nanotubes, and as an insecticide. It’s also significant in the dissolution of organic compounds for NMR measurements.
Properties of Carbon Disulfide
With a melting point of -112.1°C and a boiling point of 46°C, carbon disulfide is known for its high volatility and flammability. It has a distinctive ethereal aroma in its pure form but generally possesses a foul odor due to impurities.
Other Information on Carbon Disulfide
1. Production Process of Carbon Disulfide
Produced industrially by heating charcoal with sulfur vapor, or by reacting natural gas with sulfur vapor in the presence of a catalyst.
2. Reaction of Carbon Disulfide
It undergoes combustion to form sulfur dioxide and carbon dioxide and reacts with chlorine to give carbon tetrachloride. It also forms complexes with primary and secondary amines and alkoxides.
3. Regulatory Information
Regulated under various laws for its evaluation, manufacture, and impact on health and the environment, carbon disulfide is treated with strict handling and storage guidelines to mitigate risks.
4. Handling and Storage Precautions
- Store in a sealed, cool, dark place away from ignition sources.
- Use with appropriate protective gear and in well-ventilated areas.
- Avoid contact with strong oxidizers and ensure thorough cleaning after handling.
