Abstract: Greases are provided which contain as EP additives sodium and potassium borates containing limited quantities of water.

Abstract: A fuel additive is disclosed having improved rust-inhibiting properties and comprises (1) from 5 to 50 weight percent of a hydrocarbyl amine containing at least 1 hydrocarbyl group having a molecular weight between about 300 and 5000, (2) from 0.1 to 10 weight percent of a C.sub.12 to C.sub.30 hydrocarbyl succinic acid or anhydride, (3) from 0.1 to 10 weight percent of a demulsifier, and (4) 40 to 90 weight percent of an inert hydrocarbon solvent. A gasoline composition is also disclosed containing from 50 to 400 ppm of the above-identified fuel additive.

Abstract: A certain fuel-soluble nitrogen-hydrocarbyl-substituted nitrogenous composition has been found to display a previously unreported detergency in the internal combustion engine when present in fuels to the extent of 10-4,000 ppm. The nitrogenous composition is composed of a hydrocarbyl group bonded to a nitrogenous substrate. The hydrocarbyl substituent contains from 30 to about 400 carbon atoms, and the nitrogenous substrate is a carbamate, urea or amide.

Abstract: Greases are provided which contain organic grease thickeners and dispersions of finely divided borates as extreme-pressure agents.

Abstract: Polyurea-based greases containing as an extreme-pressure additive an alkali metal triborate introduced or produced in the grease in aqueous solution.

Abstract: An extreme pressure lubricant is provided comprising a major portion of a lubricating oil or grease and a minor portion of an extreme pressure additive which is a partial ester of a di- or tricarboxylic acid of 21 to 80 carbon atoms alone or in combination with either or both of a hydrocarbylthio ether and a phosphate ester.

Abstract: An extreme pressure lubricant is provided comprising a major portion of a lubricating oil or grease and a minor portion of an extreme pressure additive which is a partial amine of a di- or tricarboxylic acid of 21 to 100 carbon atoms alone or in combination with carbon or both of a hydrocarbylthioether and a phosphate ester.

Abstract: Wax-flux compositions for use in low-temperature soldering processes comprise (A) a major amount of a wax and (B) an effective amount to cause fluxing, at or below the soldering temperature of the piece to be soldered, of a wax-soluble product obtained by first reacting an aliphatic hydrocarbon-substituted succinic acid or derivative thereof which is capable of forming carboximide bonds with an alkylene polyamine to form a carboximide and then reacting said carboximide with an alkylaryl sulfonic acid. A process for soldering electrical components to a printed circuit board comprises (A) applying a molten wax-flux composition as described above to the metal pattern side of the board, (B) allowing the wax-flux composition to solidify, (C) trimming the components leads, and (D) soldering the components to the printed circuit board.

Abstract: A mixture of high and low molecular weight hydrocarbyl amines exhibit excellent detergency and dispersancy at low concentrations in fuels. The high molecular weight hydrocarbyl amine contains at least one hydrocarbyl group having a molecular weight from about 1,900 to 5,000 and the low molecular weight hydrocarbyl amine contains at least one hydrocarbyl group having a molecular weight from about 300 to 600. The weight ratio of low molecular weight amine to high molecular weight amine in the mixture is maintained between about 0.5 and 5:1.

Abstract: The reaction products of hydrocarbyl-substituted amines with certain polyfunctional coupling agents, find use as detergents in distillate fuel compositions. The hydrocarbyl group is normally derived from natural sources or polyolefins of from about 420 to 10,000 average molecular weight. The polyfunctional coupling agents are certain polyhalides, polycarboxylic acids, and organic polyisocyanates.
