A lubricating oil composition characterised in that it comprises a succinic acid derivative and an amide compound as additives, and a base oil selected from a mineral oil, a synthetic oil, and mixtures thereof. The lubricating oil composition of the present invention has excellent rust-preventing properties, a reduced friction coefficient and excellent energy-saving characteristics.
The anti-shudder durability of power transmitting fluids, particularly automatic transmission fluids, is improved by incorporating a combination of low potency friction modifiers and phosphorus-containing compounds. The anti-shudder durability of these fluids may be further enhanced by inclusion of a metallic detergent and/or a polyol ester friction modifier.
所要求保护的发明涉及通过使聚四氢呋喃与至少一种C9‑C27酸反应而制备的聚亚烷基二醇酯在润滑油组合物中的用途。
一种脂肪酸酯类无灰防锈剂，是由饱和或不饱和脂肪酸与多羟基有机胺化合物经过酯化反应生成的脂肪酸酯化合物。该防锈剂的制备方法是：将1-2摩尔饱和或不饱和脂肪酸与1摩尔多羟基有机胺化合物混合，加入适量的120#或200#溶剂油，在90-160℃进行酯化反应，直至脱出理论量的水，然后蒸馏除去溶剂油。本发明涉及的无灰防锈剂不但具有良好的溶解性、防锈性和抗乳化性，同时具有较低的酸值和一定的碱值，在工业润滑油中具有广泛的用途。
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.
A lubricating base stock useful for forming lubricants such as multigrade automotive oils, automatic transmission oils, greases and the like is prepared by hydroisomerizing a waxy hydrocarbon feed fraction having an initial boiling point in the 650-750 DEG F range and an end point of at least 1050 DEG F, synthesized by a slurry Fischer-Tropsch hydrocarbon synthesis process. The hydro-isomerization forms a hydroisomerate containing the desired base stock which is recovered, without dewaxing the hydroisomerate. The hydroisomerization is conducted at conditions effective to convert at least 67 wt.% of the 650-750 DEG F + waxy feed hydrocarbons to lower boiling hydrocarbons. When combined with a standard lubricant additive package, these base stocks have been formed into multigrade automotive crankcase oils, transmission oils and hydraulic oils meeting the specifications for these oils.
There is disclosed a process for the solubilization of a mercaptobenzothiazole amine salt with a solvent such as dihexyl phthalate which solubilized salt is in turn suitable for dissolution into a lubricating oil composition, such as an automatic transmission fluid, even at room temperature.
