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.
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
The Wohl–Ziegler reaction [1] [2] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N-bromosuccinimide and a radical initiator. [3] Best yields are achieved with N-bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [4] [5]
Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl 4): CHCl 3 + Cl 2 → CCl 4 + HCl The output of this process is a mixture of the four chloromethanes: chloromethane , methylene chloride (dichloromethane), trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride).
Apart from the decomposition of N 2 O 5 at high temperatures, it can also be decomposed in carbon tetrachloride CCl 4 at 30 °C (303 K). [20] Both N 2 O 5 and NO 2 are soluble in CCl 4 and remain in solution while oxygen is insoluble and escapes. The volume of the oxygen formed in the reaction can be measured in a gas burette.
1,1,1,3,3,3-Hexachloropropane is a compound of chlorine, hydrogen, and carbon, with chemical formula C 3 Cl 6 H 2, specifically Cl 3 C−CH 2 −CCl 3. Its molecule can be described as that of propane with chlorine atoms substituted for the six hydrogen atoms on the extremal carbons.
Hafnium tetrachloride is the precursor to highly active catalysts for the Ziegler-Natta polymerization of alkenes, especially propylene. [16] Typical catalysts are derived from tetra benzylhafnium . HfCl 4 is an effective Lewis acid for various applications in organic synthesis .
