  通过复分解将脂肪酸甲酯转化为二元酯及其润滑性能。

  摘要：

  生物柴油工厂正在努力寻找脂肪酸甲酯 (FAME) 的增值应用。FAME 增值的一种选择是二元酯，它可以与 2-乙基己基 (2EH) 或其他醇进行酯交换，以生产润滑油基础油并达到最广泛的粘度等级 VG46 和 VG32。生物催化、复分解和其他合成途径可用于生产二元酯。在本研究中，使用钌基催化剂，油酸甲酯通过复分解转化为单不饱和二元酯，并在与 2EH 进行酯交换后达到 VG22。其他二元酸的合成 2EH 酯表现出明显的粘度趋势。它们的相关性表明，如果转化为 2EH 二元酯，来自 gondoic 和芥酸的 FAME 应分别产生 VG32 和 VG46。当保留单不饱和度时，倾点表现出优异的低温流动性和耐热稀化性。氧化稳定性仍然可以接受，挥发性低于 VG46 矿物油。混合醇、酸和酯也可用于满足 VG 规格或实现更高的生物基含量。目前，石油化工酯基础油在高性能液压油 (HF) 中占主导地位。然而，在生物柴油工厂中将

  A solid catalyst for olefin polymerization and a process for producing an olefin polymer are provided. The polymer has a small content of a component which is dissolved out into a low temperature organic solvent, such as a low-molecular weight component and an amorphous component. The solid catalyst is obtained by bringing a solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an aliphatic carboxylate; an organoaluminum compound; and a compound represented by formula (I) into contact with each other: wherein R 1 is a hydrocarbyl group having 1 to 10 carbon atoms, R 2 is a hydrogen atom, a halogen atom or a hydrocarbyl group having 1 to 16 carbon atoms, and the R 1 the R 2 groups are independently the same or different, and the respective R 1 groups and R 2 groups may be joined with each other to form a ring.

  fatty acid methyl esters (FAME). One option for FAME valorization would be dibasic esters, which can be transesterified with 2-ethylhexyl (2EH) or other alcohols to produce lubricant basestocks and achieve the most widespread viscosity grades VG46 and VG32. Biocatalytic, metathesis and other synthetic pathways are available to produce dibasic esters. Using a ruthenium-based catalyst, methyl oleate
