  A new compound that comprises a branched ester based primarily on renewable resources preferably has good friction properties, a low pour point; acceptable viscosity, and good thermal oxidative stability and is useful as a functional fluid such as a lubricant. The branched ester is a double ester of a polyhydric alcohol having at least two active hydrogen groups separated by at least one carbon atom, wherein each hydroxyl group of the polyhydric alcohol is esterified with one monobasic secondary hydroxy fatty acid group and each hydroxyl of a fatty acid is esterified with one alkyl or cycloalkyl monobasic carboxylic acid group that has from 2 to 22 carbon atoms.

  一种新的化合物，主要基于可再生资源，包含主要是支链酯，最好具有良好的摩擦性能、低倾点、可接受的粘度和良好的热氧化稳定性，可用作功能流体，例如润滑剂。支链酯是一种双酯，由至少有两个活性氢基团的多羟基醇组成，这些基团之间至少间隔一个碳原子，其中多羟基醇的每个羟基都与一个一元二次羟基脂肪酸基团酯化，脂肪酸的每个羟基都与一个具有2至22个碳原子的烷基或环烷基一元酸基团酯化。

  α-Methylcinnamyl (MEC) esters are converted into parent carboxylic acids under mild conditions, various functions being tolerated including acetoxy, siloxy, MEM, and so on. Furthermore, MEC esters are transformed into other esters through CsF-promoted alkylation of intermediary organotin carboxylates.

  在温和的条件下，α-甲基肉桂基（MEC）酯可转化为母体羧酸，可耐受多种功能，包括乙酰氧基，甲硅烷氧基，MEM等。此外，MEC酯通过CsF促进的中间有机锡羧酸酯的烷基化转化为其他酯。
