摘要:
The present technology is related to imide containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight ranging from 300 to 750, and the use of such quaternary ammonium salts in fuel compositions to improve the water shedding performance of the fuel composition.
摘要:
The present invention provides an application of nano copper in a cutting fluid. The nano copper is self-dispersible nano copper with an organic long-carbon chain, wherein the surface of copper metal is coated with a long carbon chain organic matter, and the long chain organic matter is dialkyl dithiophosphoric acid (HDDP) and a derivative thereof. In the present invention, the nano copper substitutes functional additives which comprises one or more of a preservative, an anti-rust agent, a sterilizing agent, a compression-resisting agent and a lubricant to solve the technical problems of the existing fluid in the prior art being unable to simultaneously have efficient anti-corrosion, anti-rust, compression-resistant, lubricating and sterilizing properties as well as the variety, the relatively high amount, the high cost and the limited selection of added additives.

A composition comprising: an oil of lubricating viscosity; an alkylated phenyl-α-naphthyl amine; and at least one oil soluble triazole or derivatives thereof. Wherein the oil soluble triazole or derivatives thereof comprises at least one oil soluble diphenylamine tolutriazole reaction product.
摘要:
The present invention relates to a lubricating composition containing (a) an oil of lubricating viscosity; and (b) a compound selected from the group consisting of: (i) an ester-containing heterocycle; (ii) an amide-containing heterocycle; and (iii) a pyrimidine, wherein the ester-containing heterocycle and the amide-containing heterocycle have a hydrocarbyl group containing 6 to 40 carbon atoms. The invention further provides for a method of supplying an internal combustion engine with the lubricating composition.
摘要:
The invention provides a lubricating composition containing (a) an oil of lubricating viscosity, (b) a phosphite having at least one hydrocarbyl group that has 4 or more carbon atoms, and (c) a compound derived from a hydroxy-carboxylic acid. The invention further relates to the use of the lubricating composition in an internal combustion engine.
摘要:
1-[di(4-octylphenyl)aminomethyl]tolutriazole is prepared in a mineral oil and blended with a liquid alkylated diphenylamine. The liquid product shows increased storage stability with respect to crystallization of the 1-[di(4-octylphenyl)aminomethyl]tolutriazole when the amine is added. This blend product can be stored for a prolonged period of time, and then utilized in a lubricant composition as an antioxidant and corrosion inhibitor.
摘要:
An engine oil comprising a major amount of a base oil and a minor amount of an additive package, wherein the additive package comprises:(A) a friction modifier compound of the formula IV: wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl group having about 8 to about 22 carbon atoms; and (B) at least one dispersant.
摘要:
Provided is a lubricant or functional fluid composition of a lubricating viscosity and including: an oil, which may include one or more polyalphaolefins; an anti-wear component which may include alkylated triarylphosphate and partially esterified alkyl phosphate; an antioxidant component which may include alkylated phenyl-alpha-naphthylamine, phenyl-alpha-naphthylamine and mixtures thereof; an anti-rust component including an alkenyl succinic acid ester anti-rust agent; and a metal deactivator component including a tolytriazole derivative. Also included are additives and additive kits for combining with an oil to form the a lubricant or functional fluid composition.
摘要:
