Carbon tetrachloride was recommended for regularly cleaning the type slugs of typewriters in office settings in the 1940s. [45] Carbon tetrachloride was the first chlorinated solvent to be used in dry-cleaning and was used until the 1950s. [46]
Carbon tetrachloride (CCl 4) was once widely used in dry cleaning as the first chlorinated solvent, but its use was abandoned after its high hepatotoxicity was discovered. 1,1,1-Trichloroethane was also used in dry cleaning, until its use was banned due to its harmful effects on the ozone layer.
Faraday was previously falsely credited for the synthesis of tetrachloroethylene, which in reality, was carbon tetrachloride. [non-primary source needed] While trying to make Faraday's "protochloride of carbon", Regnault found that his compound was different from Faraday's. Victor Regnault stated "According to Faraday, the chloride of carbon ...

Structure and properties Index of refraction, n D: 1.460 Abbe number? Dielectric constant, ε r: 2.2379 ε 0 at 20 °C : Bond strength? Bond length: 175pm Bond angle: 109.5° Cl–C–Cl
In addition, a variety of simple chlorinated hydrocarbons including dichloromethane, chloroform, and carbon tetrachloride have been isolated from marine algae. [7] A majority of the chloromethane in the environment is produced naturally by biological decomposition, forest fires, and volcanoes. [8]
These chlorinated compounds are emitted during cleaning applications, some of which are toxic and probable human carcinogens. The study showed that indoor air concentrations significantly increase (8–52 times for chloroform and 1–1170 times for carbon tetrachloride, respectively, above baseline quantities in the household) during the use of ...
For frequent and industrial use, cleaning and degreasing may be replaced by supercritical carbon dioxide or dry Ice blasting, which is abrasive. This requires a setup to apply the carbon dioxide. While the harmful vapors are eliminated, the CO 2 must be ventilated. Applying the carbon dioxide causes electrostatic discharge by the expanding gas.
