Шаблон:Chembox 1,2,3-Trichlorobenzene is an organochlorine compound with the chemical formula Шаблон:Chem2.[1][2] This is one of three isomers of trichlorobenzene; the two others are 1,2,4-Trichlorobenzene and 1,3,5-Trichlorobenzene.
Synthesis
1,2,3-Trichlorobenzene can be prepared via dehydrohalogenation of hexachlorocyclohexane. Also, 1,3,5-trichlorobenzene is formed as a byproduct. Small amounts of 1,2,3-trichlorobenzene can also be produced while chlorinating benzene with iron(III) chloride as a catalyst.[3]
Physical properties
The compound forms white crystals with a faint aromatic odor. It is combustible[4] and poorly soluble in water.[5] The substance is irritating to eyes and the respiratory tract.
Uses
1,2,3-Trichlorobenzene is used as a herbicide.[5][6] Also as a solvent for high-melting products, as a coolant in electrical installations and glass tempering.[7]
