[Uses]

trans-1,2-cyclohexanedicarboxylic acid be used as organic intermediates.
[Purification Methods]

It is purified by recrystallisation from EtOH or H2O. It is formed by hydrolyzing the anhydride with water. The dimethyl ester has m 95-96o (from *C6H6/pet ether). [Abell J Org Chem 22 769 1957, Smith & Byrne J Am Chem Soc 72 4406 1950, Linstead et al. J Am Chem Soc 64 2093 1942, Beilstein 9 III 3812, 9 IV 2801.] The 1R,2R-(-)-trans-cyclohexane-1,2-acid [46022-05-3] has m 171-182o and [ ] D -20o (c 1, Me2CO). cis-Cyclohexane-1,2-dicarboxylic anhydride (cis-hexahydrophthalic anhydride) [85-42-7, 13149-00-3] M 154.2, m 32-34o, b 158o/17mm. It has been obtained by heating the trans-acid or anhydride at 200o. Crystallise it from *C6H6/Et2O or distil it.
