METHOD FOR PRODUCING 1,6-HEXANE DIOL COMPOSITION, 1,6-HEXANE DIOL COMPOSITION, AND POLYMER

WIPO Patent Application WO/2024/018980

A1

The purpose of the present invention is to provide: an environmentally friendly method for producing a 1,6-hexane diol composition which is derived from biomass resources and which has excellent reactivity; a 1,6-hexane diol composition which has excellent reactivity and which is obtained using said production method; and a polymer having excellent reactivity, which is obtained by reacting said 1,6-hexane diol composition. This production method relates to a method for producing a 1,6-hexane diol composition, the method including: a step (1) for producing a 1,6-hexane diol composition from 6-hydroxycaproic acid and/or a derivative thereof obtained from a raw material derived from biomass resources; and step (2) for purifying the 1,6-hexane diol composition obtained in step (1) by carrying out ion exchange and/or distillation.
