Abstract

The invention comprises 2-hydroxy-3,5,6-trichlorobenzyl alcohol, which is prepared by reacting 2,4,5-trichlorophenol with formaldehyde in the presence of an alkali. The alkali may be an alkali metal carbonate or hydroxide or an alkaline earth metal oxide or hydroxide. In examples of the preparation alkalis used are sodium hydroxide, sodium carbonate and calcium hydroxide. The reaction is carried out by heating the trichlorophenol and formaldehyde in an aqueous solution of the alkali. Specification 760,342 is referred to.
