Abstract

Basic copper chloride is produced by oxidising cuprous chloride in an aqueous solution containing at least 20% sodium chloride, by weight, with oxygen or air, the pH of the solution being maintained at 3.5 to 5, preferably at 4.0-4.5, and the temperature being 0 DEG C.-120 DEG C., preferably 60 DEG -75 DEG C. The pH range may be obtained by the addition of alkali or alkaline earth liquors, compounds which are alkaline on hydrolysis, and amines, for example by adding solutions of sodium or potassium hydroxide, calcium hydroxide, ammonia, alkylamines, alkali metal phosphates or carbonates, and sodium methylate or ethylate. A dispersing agent, for example alkaryl sulphonates, ethoxylated long chain alcohols or carboxylic acids, alkyl sulphonates, or sulphosuccinic acid esters, such as succinic acid dinonyl sulphonate, may be added.
