摘要:
Amine salts of carboxylate half esters of 1-aza-3,7-dioxabicyclo [3.3.0] oct-5-yl methyl alcohols which are the reaction products of organic acid materials, preferably long chain dicarboxylic anhydrides such as octadecenyl and polyisobutenylsuccinic anhydrides and aldehyde/tris [hydroxymethyl]aminomethane (THAM) adducts or mixtures are anti-rust additives for hydrocarbon fuels, such as gasoline and middle distillates.

摘要:
A neutral oil soluble organosulfonic acid ammonium salt formed by reaction of C.sub.1 -C.sub.26 sulfonic acid with a nitrogen base chosen from the group consisting of mono-, di-, and tertiary amines, acid addition salts of such amines, or quaternary ammonium compounds, the nitrogen base having at least one hydrocarbyl group containing from about C.sub.1 to C.sub.36 carbon atoms, is added to an oil composition to improve the load-carrying capacity of the oil composition. The sulfonic ammonium salts are particularly effective in synthetic ester lubricants used in turbine engines. The oil compositions of this invention are also compatible with the silicone and fluorosilicone seals used in such engines.
摘要:
Synthetic ester lubricant blends are described which contain 1-90 weight percent of an N-substituted polyoxyalkylene phenothiazine. The polyoxyalkylene group can be derived from ethylene, propylene, butylene or styrene oxides. The blends have superior oxidative and thermal stability and at the same time have good viscosity characteristics and pour points over a wide range of temperatures.
摘要:
Compositions useful as lubricants and functional fluids comprise an oleaginous liquid of lubricating viscosity, typically a mineral oil, and an oxygen-, sulfur- or nitrogen-containing polyfunctional nitrile. The preferred nitriles are cyanoethylation products of alcohols, mercaptans and amines, and especially of alcohols. The polyfunctional nitrile serves as a seal swelling agent and/or demulsifier.
