Abstract

1:4-Cyclohexanedimethanol containing the trans-isomer in excess of the percentage of trans-isomer present in the 1:4-cyclohexanedicarboxylic acid dialkyl ester from which it is obtained, is prepared by heating the diester (e.g. the dimethyl ester), preferably under superatmospheric pressure and in absence of a catalyst, at a temperature of at least 250 DEG C. (e.g. 280-400 DEG C.) and converting the reaction product to 1:4-cyclohexanedimethanol, e.g. by reduction with hydrogen in presence of copper chromite. Specification 818,157 and U.S.A. Specification 2,917,549 are referred to.
