  • Patent number: 11492316
    Abstract: The present disclosure relates to the technical field of hexanediol production, and provides a production method and a production device of high-purity 1,6-hexanediol. A dipic acid and a C6 mixed alcohol are mixed to conduct esterification to obtain a product feed liquid including an adipic acid diester, and the high-purity 1,6-hexanediol is obtained through hydrogenation reduction and distillation. In addition to being used as a reaction raw material, the C6 mixed alcohol further acts as a water-carrying agent; water produced by the esterification is removed by azeotropy, thereby promoting a smooth reaction process to realize the esterification without a catalyst. The method does not need the catalyst during esterification, and the subsequent hydrogenation reduction can be directly conducted with no complicated post-treatment procedure required after the esterification.
