METHOD OF PRODUCING DIMETHYL TRANS-1,4-CYCLOHEXANEDICARBOXYLATE, AND HIGH PURITY DIMETHYL TRANS-1,4-CYCLOHEXANEDICARBOXYLATE

摘要

PROBLEM TO BE SOLVED: To provide a production method which can efficiently obtain high purity dimethyl trans-1,4-cyclohexanedicarboxylate, and to provide the high purity dimethyl trans-1,4-cyclohexanedicarboxylate. SOLUTION: The method of producing dimethyl trans-1,4-cyclohexanedicarboxylate comprises: a process (I) which isomerizes dimethyl cis-1,4-cyclohexanedicarboxylate or dimethyl cis/trans mixture-1,4-cyclohexanedicarboxylate by an isomerization catalyst; and a process (II) which crystallizes a mixture obtained by the process (I).
