Abstract
Polyol polyesters having reduced color content are prepared by base-catalyzed transesterification of pretreated lower (i.e., C.sub.1 -C.sub.3) alkyl fatty esters with polyols. The pretreatment comprises the steps of contacting the alkyl fatty esters (in a liquid state) with an alkoxide base, separating undissolved solids from the esters, and then distilling the esters.
