Tetrachloromethane (carbon tetrachloride) CCl4 is a colorless heavy liquid that smells like chloroform. Non-flammable.
Reacts explosively with alkali metals. The liquid is extremely poisonous, its vapors are also toxic. When heated with water to 250 В° C, hydrolysis occurs: with a lack of water, phosgene is formed, with an excess, carbon dioxide.
When heated to 500 В° C, it turns into a mixture of tetrachlorethylene and hexachloroethane with the release of free chlorine. It is used as a solvent (fats, resins, rubber, etc.), to obtain freons, as an extractant, in medicine.
