由家蝇（Musca domesticaL.）以城市垃圾为饲料的幼虫是一种可再生的油脂资源，但由于其低温性能差，不饱和度低，不能产生作为润滑剂的正丙烷脂肪酸三酯。以家蝇幼虫油脂为原料，合成了一种新型脂肪酸酯复合物，该复合物由正丙烷脂肪酸三酯和2-乙基己基脂肪酸酯组成。从分子蒸馏中分离出的酰基甘油首先被酯交换成脂肪酸甲酯，然后与正丙烷进一步酯交换成正丙烷酯。纯化的正丙烷脂肪酸三酯的纯度为98.4%，并进一步与30重量%的来自家蝇幼虫游离脂肪酸的2-乙基己基脂肪酸酯共混。倾点从-3 °C显著降低到-12 °C，同时润滑性能在ISO VG 32的标准内，与纯的正丙烷脂肪酸三酯相比，水分离性略有改善。将两种粘度和倾点优势不同的生物润滑剂进行复配，以饱和非食品油脂源代替不饱和天然植物油，制备出性能优良的酯复合物。该研究也为非食品油脂行业的高附加值产品生产提供了一种清洁、节能的方法。
Lipid generated from housefly (Musca domesticaL.) larvae fed by municipal waste is a renewable lipid resource, however, the low unsaturated degree prevents it from producing trimethylolpropane fatty acid triester as lubricant, due to its poor low-temperature performance. A new fatty acid esters complex consisting of trimethylolpropane fatty acid triester and 2-ethylhexyl fatty acid ester was produced from housefly larval lipid. Separated from molecular distillation, the acylglycerols were first trans-esterified into fatty acid methyl ester and then further trans-esterified with trimethylolpropane into trimethylolpropane esters. The purified trimethylolpropane fatty acid triester is with purity of 98.4% and further blended with 30 wt% 2-ethylhexyl fatty acid ester derived from housefly larval free fatty acid. The pour point was substantially lowered from −3 °C to −12 °C while the lubricity performance is within standard of ISO VG 32, with minor improvement of water separability compared with pure trimethylolpropane fatty acid triester. By blending two type bio-lubricants with different advantages on viscosity and pour point, the ester complex with favorable properties was produced using saturated non-food lipid source rather than unsaturated virginal vegetable oil. This study also offers a cleaner and energy-efficient approach for high value-added product production for non-food lipid industry.
