Abstract
A process for preparing 4-chloro-2-hydroxybenzothiazole comprising diazotizing 2-amino-4-chlorobenzothiazole halohydrate and hydrolyzing the product, diazotization being carried out in the presence of a halogenated aliphatic hydrocarbon solvent in which the main products of the reaction of Diazotisation are soluble in a proportion of up to at least 10% by weight/volume at 20ºC.
