Description

A volatile liquid with a characteristic odor. Chloroform was synthesized in 1831 by Liebig and Soubeiran. It was first used as a general anesthetic in 1847 by Sir James Simpson, a physician in Edinburgh. Chloroform is a good Solvent for fats, oils, Rubber, waxes, and resins. It has been used as a cleaning fluid, refrigerant, degreaser, Insecticide, and Fumigant.

Risks

Carcinogen. Toxic by inhalation, ingestion and skin absorption. Nonflammable.

Chloroform can decompose when exposed to heat, moisture and UV light forming highly toxic fumes (phosgene, chlorine gas and hydrogen chloride). Reacts violently with bases, oxidants and some metals (e.g.,aluminium, lithium, magnesium, potassium, sodium), causing fire and explosion hazard. Attacks plastic, rubber and coatings.
