Title:
EFFICIENT METHOD FOR PRODUCING AND PURIFYING ANHYDROUS SUGAR ALCOHOL
Document Type and Number:
WIPO Patent Application WO/2016/105107
Kind Code:
A3
Abstract:
The present invention relates to a method for producing and purifying an anhydrous sugar alcohol in high yield and to a high degree of purity by means of a simple process and device, the invention comprising: a step in which a sugar alcohol and an acid catalyst are reacted in a reactor while at the same time evaporating the product therefrom; a step in which the evaporated product is cooled so as to remove water and obtain a crude anhydrous sugar alcohol; and a step in which the crude anhydrous sugar alcohol is introduced into a melt-crystallization process, thereby obtaining a high purity anhydrous sugar alcohol.
