Abstract

In accordance with the present disclosure there is provided a simple and selective process for preparing purified dianhydrosugar alcohols. The process involves dehydration of sugar alcohol in the presence of acid catalysts to obtain a reaction mixture containing a crude dianhydrosugar alcohol and unreacted acid catalyst. The colored impurities formed during the preparation of the crude dianhydrosugar alcohol are then effectively eliminated by first dispersing the crude dianhydrosugar alcohol in a suitable diol and then adsorbing the colored impurities by means of adsorption aids. In accordance with the present disclosure there also is provided an integrated process for preparing a polymer by employing the purified dianhydrosugar alcohols.
