  油酸二酯：合成，低温性能和氧化稳定性

  摘要：

  AbstractSeveral diesters were prepared from commercially available oleic acid and common organic acids. The key step in the three step synthesis of oleochemical diesters entails a ring opening esterification of alkyl 9,10‐epoxyoctadecanoates (alkyl: propyl, isopropyl, octyl, 2‐ethylhexyl) using propionic and octanoic acids without the need for either solvent or catalyst. Each synthetic diester was evaluated for both low temperature operability and oxidation stability through measurement of cloud point, pour point, oxidation onset temperature, and signal maximum temperature. It was discovered that increasing chain length of the mid‐chain ester and branching in the end‐chain ester had a positive influence on the low temperature properties of diesters. Improved oxidation stability is achieved when the chain length of the mid‐chain ester is decreased. Additionally, the mid‐chain ester plays a larger role in oxidation stability than the end‐chain ester. These products may prove useful in the search for bio‐based industrial materials, such as lubricants, surfactants, and fuel additives.

  Industrial grade cation-exchange resin “INDION 130” was modified with vanadyl cations by an ion-exchange method and then used for the epoxidation of unsaturated fatty materials including acids, esters and vegetable oils using tert-butyl hydroperoxide (TBHP) in decane as oxidant. The effect of oxidant/double bond ratio, catalyst concentration, recycling of the catalyst and temperature on the conversion

  工业级阳离子交换树脂“ INDION 130”通过离子交换方法用钒基阳离子改性，然后用于癸酸中的氢过氧化叔丁基（TBHP）作为氧化剂，对不饱和脂肪材料（包括酸，酯和植物油）进行环氧化。研究了氧化剂/双键比率，催化剂浓度，催化剂的循环利用和温度对转化为环氧化物的影响。环氧化后，可以很容易地通过过滤回收催化剂，并且可以成功地重复使用至少7次，而不会损失任何催化活性。
