    摘要: The present invention relates to a process for lightening the color of polyol esters by reacting polyols with linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms, wherein the reaction product is worked up without using adsorbents and comprises a treatment with peroxidic compounds and an immediately subsequent steam treatment with subsequent drying.
