• Heterogeneously Catalysed Synthesis of New 3-Alkoxypivalic Acids from Substituted 1,3-Dioxanes
  作者：Jutta Fischer、Wolfgang F. Hölderich

  DOI：10.1006/jcat.2000.2956

  日期：2000.9

  3-alkyloxypivalic acids starting from substituted 1,3-dioxanes were examined. While one-step procedures combining isomerisation and oxidation were not successful due to degradation of formed intermediates and products, a two-step environmentally benign method could be established using O2 as oxidant in the presence of heterogeneous catalysts. The scope of the method was tested by use of several 1,3-dioxanes and

  从取代的1，3-二恶烷开始，研究了几种制备有趣和有价值的化合物3-烷氧基新戊酸的方法。尽管由于形成的中间体和产物的降解，将异构化和氧化相结合的一步法不成功，但是可以在异相催化剂存在下使用O 2作为氧化剂建立一种两步法环境友好的方法。该方法的范围通过使用几种1,3-二恶烷进行了测试，并对分离出的新戊酸衍生物进行了表征。

  The invention relates to novel compositions of matter which may advantageously be used as lubricants or pressure transfer media or else for functional liquids and lubricant additives. The lubricants according to the invention are the reaction products of an electro-philic addition of linear or branched, aliphatic or aromatic carboxylic acids, carboxylic anhydrides, carbonyl halides or novel neoacids to the double bonds of fatty acids, esters thereof and/or of other fatty acid derivatives and also of synthetic esters. Owing to their increased oxidation resistance compared to the starting materials and also their low toxicity, the novel class of synthetic esters based on oleochemicals may find use in novel environmentally compatible lubricants, pressure transfer systems, functional liquids and lubricant additives.

  本发明涉及一种新型物质组成，可优势地用作润滑剂或压力传递介质，或者用于功能液体和润滑剂添加剂。根据本发明，润滑剂是线性或支链的，脂肪族或芳香族羧酸，羧酸酐，羰基卤化物或新型新酸通过亲电加成反应与脂肪酸，其酯和/或其他脂肪酸衍生物以及合成酯的双键反应生成的产物。由于与起始材料相比具有较高的氧化抵抗性和低毒性，基于油脂化学的新型合成酯类可以用于新型环境兼容的润滑剂、压力传递系统、功能液体和润滑剂添加剂。
