trans-1,2-Cyclohexanedicarboxylic acid Usage And Synthesis

Chemical Properties	white crystalline powder
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.
