US 10,766,842 B2 · Anhydrosugar alcohol composition having enhanced storage stability, and anhydrosugar alcohol storage method

Abstract

The present invention relates to an anhydrosugar alcohol composition having enhanced storage stability, and an anhydrosugar alcohol storage method, and more specifically, to an anhydrosugar alcohol composition having enhanced storage stability by comprising anhydrosugar alcohol and an amine-based additive; and to a method by which anhydrosugar alcohol having excellent quality may be provided by having the storing of the anhydrosugar alcohol performed under the existence of the amine-based additive, thereby remarkably enhancing the storage stability of the anhydrosugar alcohol.

A composition comprising

a concentrated anhydrosugar alcohol;
and
an amine compound as an additive for stabilization;
wherein the concentrated anhydrosugar alcohol is dianhydrohexitol in solid form,
wherein the amine compound is selected from the group consisting of piperidine, 1,8-diazabicycloundec-7-ene, 1,5-diazabicyclo[4.3.0]non-5-ene and combinations thereof, each of which is unsubstituted or substituted with one or more substituents selected from the group consisting of linear or branched C1-C10alkyl, C3-C10cycloalkyl, aminoC1-C10alkyl, mono- or di-C1-C10alkylaminoC1-C10alkyl, carboxamide and amino, and
wherein an amount of the amine compound is 1 ppm or more and 300 ppm or less, based on a weight of the concentrated anhydrosugar alcohol.
