  A process for preparing polyol esters by reacting polyols with linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms, is characterized in that a mixture of the starting compounds is allowed to react in the presence of a Lewis acid containing at least one element of groups 4 to 14 of the periodic table of the elements as a catalyst and in the presence of an adsorbent with removal of the water formed, and then the crude ester obtained is aftertreated by adding a further adsorbent which is an acidic activated carbon having a pH of 1 to 6.5.

  通过将具有3至20个碳原子的线性或支链脂肪族一元羧酸与多元醇反应来制备聚醇酯的方法，其特征在于允许起始化合物的混合物在含有周期表元素4至14族中至少一个元素的路易斯酸存在下反应，并在吸附剂的存在下去除生成的水，然后通过添加具有pH值为1至6.5的酸性活性碳的进一步吸附剂对得到的粗酯进行后处理。

  A batchwise process for aftertreatment of polyol esters prepared by reacting polyols of the general formula (II) H—(—O—[—CR 1 R 2 —] m —) o —OH   (II) in which R 1 and R 2 are each independently hydrogen, an alkyl radical having 1 to 5 carbon atoms, preferably methyl, ethyl or propyl, or a hydroxyalkyl radical having 1 to 5 carbon atoms, preferably the hydroxymethyl radical, m is an integer from 1 to 10, preferably 1 to 8 and especially 1, 2, 3 or 4, o is an integer from 2 to 15, preferably 2 to 8 and especially 2, 3, 4 or 5, with excess linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms and having a lower boiling point than the polyols used. The process is carried out in the presence of a Lewis acid and in the presence of an adsorbent, while removing the water formed, characterized in that the excess monocarboxylic acid is removed by distillation and water is added to the crude ester obtained at a temperature below the boiling point of water at the particular pressure and the crude ester with added water is aftertreated with avoidance of basic compounds, and the sparingly soluble conversion products and the adsorbent present in the esterification reaction are filtered off.
