  The present invention relates to a process for preparing polyol esters by reacting polyols with linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms by partial recycling of the aliphatic monocarboxylic acid removed into the esterification reaction or into subsequent esterification batches.

  本发明涉及一种通过将多元醇与具有3至20个碳原子的线性或支链脂肪族一元羧酸反应，通过将从酯化反应中去除的脂肪族一元羧酸部分回收到酯化反应或随后的酯化批次中制备聚醇酯的方法。

  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.

  本发明涉及一种通过将多元醇与具有3至20个碳原子的直链或支链脂肪族单羧酸反应制备聚醇酯的方法，其中反应在存在作为催化剂的周期表元素4至14族中至少一个元素的路易斯酸和吸附剂的情况下进行，并且随后将反应产物进行蒸汽处理。

  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.

  Dibasic esters (diesters) and their use in plasticizer compositions are generally disclosed. In some embodiments, the diesters are branched-chain esters of long-chain alkanedioic acids, such as octadecanedioic acid. In some embodiments, such plasticizer compositions are used to increase the plasticity of a polymer resin, such as a vinyl chloride resin or poly vinyl butyral. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In some embodiments, at least a portion of the plasticizer is derived from a renewable source, such as a natural oil.

  二元酯（双酯）及其在增塑剂组合物中的使用通常是公开的。在某些实施例中，这些双酯是长链二羧酸的支链酯，如十八烷二羧酸。在某些实施例中，这种增塑剂组合物用于增加聚合物树脂的可塑性，如氯乙烯树脂或聚酮醇树脂。在另一些实施例中，这种增塑剂组合物用于降低聚合物树脂的玻璃化转变温度。在某些实施例中，至少部分增塑剂是来自可再生来源，如天然油。
