IMPROVED SYNTHESIS OF ANHYDROGLYCITOL ESTERS OF IMPROVED COLOUR
摘要
<p>Diesters of dianhydroglycitols can be prepared by esterification of dianhydroglycitols, anhydroglycitols and/or glycitols with alkylcarboxylic or arylcarboxylic acids in the presence of an acid catalyst, the acid catalyst being a macroporous acid ion exchange resin. If glycitols or monoanhydroglycitols are used as the starting material, the reaction temperature is initially of the order of 120 DEG C and after the dehydration is approximately 140 DEG C.</p>
