  公开（公告）日：2017-09-14

  A process for preparing trans-enriched MDACH, including: distilling an MDACH starting mixture in the presence of an auxiliary, which is an organic compound having a molar mass of 62 to 500 g/mol, a boiling point at least 5° C. above the boiling point of cis,cis-2,6-diamino-1-methylcyclohexane, and 2 to 4 functional groups, each of which is independently an alcohol group or a primary, secondary or tertiary amino group. The MDACH starting mixture includes 0 to 100% by weight of 2,4-MDACH and 0 to 100% by weight of 2,6-MDACH, based on the total amount of MDACH present in the MDACH starting mixture. The MDACH starting mixture includes both trans and cis isomers. Trans-enriched MDACH includes 0 to 100% by weight of 2,4-MDACH and 0 to 100% by weight of 2,6-MDACH, where the proportion of trans isomers in the mixture is higher than the proportion of trans isomers in the MDACH starting mixture.

  制备富含反式异构体MDACH的方法，包括：在辅助剂的存在下蒸馏MDACH起始混合物，所述辅助剂是一种有着62至500克/摩尔的摩尔质量、沸点至少比顺式、顺式-2,6-二氨基-1-甲基环己烷的沸点高出至少5摄氏度，并且具有2至4个官能团，每个官能团独立地是醇基团或一级、二级或三级氨基团的有机化合物。MDACH起始混合物包括以MDACH起始混合物中MDACH总量为基础的0至100%重量的2,4-MDACH和0至100%重量的2,6-MDACH。MDACH起始混合物包括反式和顺式异构体。富含反式异构体的MDACH包括以2,4-MDACH和2,6-MDACH的0至100%重量为基础，其中混合物中反式异构体的比例高于MDACH起始混合物中反式异构体的比例。
