  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.
