Abstract
The present invention relates to a process for preparing polyol esters by reacting polyols with linear or branched aliphatic monocarbocxylic acids having 3 to 20 carbon atoms, the reaction taking place in the presence of a Lewis acid comprising at least one element from groups 4 to 14 of the Periodic Table of the Elements as catalyst, and in the presence of an adsorbent, the reaction product being subjected subsequently to a steam treatment.
