Chlorotoluene

The chlorotoluenes form a group of substances derived both from toluene and from chlorobenzene in chemistry. The structure consists of a benzene ring with an added methyl group (- CH3) and chlorine ( -Cl) as a substituent. Due to their different arrangement of three structural isomers arise with the formula C7H7Cl.

Properties

The chlorotoluenes are virtually insoluble in water; However, they are with other organic solvents, such as benzene, alcohol, ether, ethyl acetate and chloroform, multimiscible. The boiling points of the three isomers are close together, while their melting points differ significantly. The 4- chlorotoluene, which has the highest symmetry, has the highest melting point.

Representation

The chlorotoluenes can be displayed from the toludines means of the Sandmeyer reaction. A mixture of 2 - and 4 -chlorotoluene is obtained by chlorination of toluene with chlorine, and iron, with iron (III ) chloride is formed as a Lewis acid.

Use

Chlorotoluenes be used as a solvent and as an intermediate in the preparation of dyestuffs, pesticides and pharmaceuticals.
