Abstract

1422726 Cyclohexane hexacarboxylic acid isomer BADISCHE ANILIN- & SODA-FABRIK AG 14 March 1973 [15 March 1972] 12209/73 Heading C2C The invention comprises the cyclohexane- 1,2,3,4,5,6 - hexacarboxylic acid of the formula in which X is a carboxyl group in equatorial position, Y is a carboxyl group in axial position and Z is a carboxyl group which is either in axial or in equatorial position and the mono-, di-, tri-, tetra-, penta- and hexa-alkali metal salts thereof. The invention also comprises dianhydrides of the formulµ Such compounds are obtained by dehydration of a known isomer of cyclohexane-1,2,3,4,5,6- hexacarboxylic acid at a temperature of from 80‹ to 300‹ C. to form the anhydride of either of the latter formulµ followed by hydrolysis. Examples describe the preparation of the free hexacarboxylic acid and sodium salts and of the dianhydrides.
