Uses and applications

What the substance is used for, by industry and function

Chemical intermediate for 2,4,6-trichlorophenol.

How it is made

Industrially by chlorination of phenol with chlorine gas in a melt in cast-iron reactors. The isomer distribution in the product may be adjusted to market demands by the chlorination level and by recycling various intermediates. The yield, based on chlorine and phenol, is greater than 95%. (Mono-, Di-, and Trichlorophenols with No Chlorine in a Meta Position)

Treatment of 2-chlorophenol with liquid sulfur dioxide, followed by gaseous chlorine with heat

Obtained by chlorinating o-chlorophenol in the presence of a catalytic quantity of an amine, with or without a solvent medium, giving a yield of 90%.
