本发明公开一种用平均分子量高于目标分子量的馏分和平均分子量低于目标分子量的馏分通过分子均化制备润滑油基础油沸程内的烃、润滑油基础油和润滑油组合物的方法。这些馏分可以通过如费托反应得到和/或通过蒸馏原油得到。分子均化能够将这些馏分转化成具有所期望分子量的产物，该产物可用于制备润滑油组合物。可任选地将该产物异构化，以降低其倾点，还可以将其与合适的添加剂组合，形成润滑油组合物。
通过包括使共聚物与至少一种醚化合物和至少一种芳族化合物反应的方法制备的油溶性的润滑油添加剂组合物。
提供了齿轮油组合物。所述组合物包含矿物油基础油料和聚α烯烃(PAO)基础油料的协同调和物，使得所述油组合物在40％的滑动/滚动比下在15mm2/s下牵引系数为0.030或更低且在80℃、20牛顿载荷和1.1m/s滚动速度下压力粘度系数为至少16.0。在一个实施方案中，基于所述齿轮油组合物的总重量，PAO基础油料的协同量为5-48wt％。
A functional fluid is disclosed which comprises in a mixture a major portion of a base oil and a minor amount of a 2-(3,4-epoxycycloalkyl)-5-5'-spiro-(3,4-epoxy) cycloalkyl-m-dioxane. The fluid may also contain a minor amount of a viscosity index improver, a small amount of water and other additives.
Disclosed herein are additives which are useful as dispersants and detergents in lubricating oils and fuels. In particular, this invention is directed toward polyamino alkenyl or alkyl succinimides wherein one or more of the amino nitrogens of the succinimide is substituted withwherein R4 is hydrocarbyl of from 1 to 30 carbon atoms; R5 is hydrocarbyl of from 2 to 30 carbon atoms or 13 R6-(OR6)p- wherein R6 is alkylene of 2 to 5 carbon atoms and p is an integer from 1 to 100; and m is an integer of from 0 to 1.
This disclosure describes an ashless lubricant additive. The additive is a tertiary amine-containing compound having the following structure: where each R1 and R5 is independently a linear or branched-chain monovalent hydrocarbyl group having two to about twenty carbon atoms, where each R2, R3, and R4 is independently a hydrogen, a linear or branched-chain monovalent hydrocarbyl group having one to about twenty carbon atoms wherein at least one of R2, R3, and R4 is hydrogen, each m is independently from 0 to 2, each p is independently from 0 to 2, for each cylic moiety m + p is from 2 to 4, and each n is independently from 1 to 6.
Disclosed herein are additives which are useful as dispersants and detergents in lubricating oils and fuels. In particular, this invention is directed toward polyamino alkenyl or alkyl succinimides wherein one or more of the amino nitrogens of the succinimide is converted to
