Abstract

Alkali or alkaline earth metal salts of an acid of formula <FORM:0934292/IV(a)/1> where X is O or S. are made by treating an alkali or alkaline earth metal salt of a ,a 1-dichloroadipic acid with an alkali metal hydroxide, or sulphide, in an aqueous medium. On acidification, with a mineral acid, the salts yield the free acids. Preferably concentrated solutions of 2 to 3 moles of hydroxide, or 1 mole of sulphide, per mole of salt are used at 50 to 110 DEG C., especially 70 to 100 DEG C. In examples sodium and calcium salts are made.
