Carbon tetrachloride (CAS NO.56-23-5) was originally synthesised in 1839 by reaction of chloroform with chlorine, from the French chemist Henri Victor Regnault,but now it is mainly synthesized from methane.
Since the 1980s，the production of carbon tetrachloride(56-23-5) has steeply declined for environmental concerns and the decreased demand for CFCs. And production in the U.S.-Europe-Japan was estimated at 720,000 tonnes in 1992.

 Carbon tetrachloride (CAS NO.56-23-5) was originally synthesised by reaction of chloroform with CHLORINE but now  it is mainly synthesized from METHANE.

Preparation: this chemical is mainly produced from methane:
CH₄ + 4 Cl₂ → CCl₄ + 4 HCl

Uses of Carbon tetrachloride: it was widely used as a dry cleaning solvent, as a refrigerant, and in lava lamps. Large quantities of carbon tetrachloride were used to produce the freon refrigerants R-11 (trichlorofluoromethane) and R-12 (dichlorodifluoromethane). Carbon tetrachloride has also been used in the detection of neutrinos. Carbon tetrachloride is one of the most potent hepatotoxins (toxic to the liver), and is widely used in scientific research to evaluate hepatoprotective agents.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. It has limited evidence of a carcinogenic effect. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible). Besides, this chemical is danger of serious damage to health by prolonged exposure through inhalation and harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. It may cause long-term adverse effects in the environment. When you are using it, wear suitable protective clothing and gloves and do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer). Please avoid release to the environment. Refer to special instructions/safety data sheet.
