Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform -like odour that can be detected at low levels.

The odor detection threshold for phosgene is 0.4 ppm, four times the threshold limit value (time weighted average). Its high toxicity arises from the action of the phosgene on the −OH , −NH 2 and −SH groups of the proteins in pulmonary alveoli (the site of gas exchange), respectively forming ester, amide and thioester functional groups in ...
It is resistant to hydrolysis and less corrosive than other chlorinated solvents. [11] It does not tend to polymerise like fluorine analogue tetrafluoroethylene, C 2 F 4. Tetrachloroethylene may react violently with alkali or alkaline earth metals, alkalis (sodium hydroxide and potassium hydroxide), nitric acid, beryllium, barium and aluminium ...
They did, however, complete the hydrolysis using dilute Et 2 O/CCl 4 at -10 °C. The purpose of completing the hydrolysis of dichlorosilane is to collect the concentrated hydrolysis products, distill the solution, and retrieve a solution of [H 2 SiO] n oligomers in dichloromethane. [3] These methods were used to obtain cyclic polysiloxanes.
CH 4 + Cl 2 → CH 3 Cl + HCl CH 3 Cl + Cl 2 → CH 2 Cl 2 + HCl CH 2 Cl 2 + Cl 2 → CHCl 3 + HCl CHCl 3 + Cl 2 → CCl 4 + HCl. The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride as well as hydrogen chloride as a byproduct. These compounds are separated by distillation.
The rate of hydrolysis is slow enough to allow the extraction of Cl 2 O with organic solvents such as CCl 4, [3] but the equilibrium constant ultimately favours the formation of hypochlorous acid. [7] 2 HOCl ⇌ Cl 2 O + H 2 O K (0 °C) = 3.55x10 −3 dm 3 /mol
