Abstract

Process for preparing xylitol esters of fatty acids possessing 6-30 carbon atoms, said esters having a high number of hydrophilic groups, characterized by heating 1 mole of xylitol with about 0.5-1 mole of the fatty acid selected at 90 -120º C for about 2 hours in the presence of an acid catalyst and in the absence of atmospheric oxygen.
