Abstract:
In the process of shaping metal surfaces and cleaning the same which comprises shaping a hard metal surface in the presence of a cutting, grinding or forming oil based on mineral oil, subjecting said shaped metal surface having a residue of said cutting, grinding or forming oil thereon to the action of an aqueous cleaning solution and recovering said shaped metal surface free of said residue of said cutting, grinding or forming oil, the improvement which comprises (A) admixing said cutting, grinding or forming oil based on mineral oil, prior to said shaping step, with from 3% to 50% by weight of an oil-soluble, (a) Addition products of 2 to 5 mols of ethylene oxide to 1 mol of a fatty compound having a replaceable hydrogen atom and 12 to 18 carbon atoms selected from the group consisting of fatty acids, fatty amines and fatty alcohols, (b) Addition products of 5 to 6 mols of ethylene oxide to 1 mol of dodecylphenol, (c) Partial esters of sorbitol with fatty acids having 12 to 18 carbon atoms in a ratio of 1.5 to 3 mols of fatty acid to 1 mol of sorbitol, and (d) Mixtures thereof; and (B) utilizing as said aqueous cleaning solution, an aqueous composition containing from 0.05% to 0.5: of said oil-soluble, nonionic emulsifier.
Abstract:
Lubricating compositions useful for lubricating high-temperature alloys are prepared by adding organosilicon compounds containing silicon-bonded ethyl groups substituted with iodine, with bromine or chlorine, and with alkoxy, acyloxy or hydroxy groups to oils of lubricating viscosity.
Abstract:
This disclosure is directed to a class of novel compounds having excellent antioxidant properties. The disclosure also relates to the use of new paraphenylene diamine derivatives for the stabilization of organic materials which tend to deteriorate due to oxidation reactions. Typical of such organic materials are liquids such as lubricating oils, alcohols, polyphenyl ethers, etc., semisolids, exemplified by greases; and solids such as high molecular weight polymers.
Abstract:
Organic compositions are provided containing secondary C6 to C9 trialkyl phenols, or their mixtures, as antioxidants for preventing oxidative deterioration of metal surfaces.
Abstract:
Novel haloalkyl substituted pyrophosophonic acid derivatives and their amine salts impart, inter alia, extreme-pressure properties to lubricant compositions especially to lubricant compositions used in gas-turbine engines.

Abstract:
ORGANIC MATERIAL IS SYNERGISTICALLY STABILIZED BY ADDITION OF BOTH AN A-ALKOXY DIHYDROCARBYL CRESOL AND A DIALKYL TIN SULFIDE SYNERGIST. FOR EXAMPLE, LUBRICATING OIL CONTAINING A-ALKOXY-2,6-DI-TERT-BUTYL-P-CRESOL AND DIBUTYL TIN SULFIDE IS EXCEPTIONALLY STABLE.
Abstract:

THE NOVEL SULFINYL COMPOUNDS ARE PREPARED BY REACTING (1) AN ALKENYLSUCCINIC ANHYDRIDE, AN ALKENYLSUCCINIC ACID OR AN ALKENYLSUCCINAMIC ACID AND (2) AT LEAST ONE SULFINYL-CONTAINING HYDROXY COMPOUND HAVING THE FORMULAS:
R1-S(=O)-(R2-O)Y-H, R1-S(=O)-R2-(O-R3-S(=O)-R4)N-OH OR
HO-(R2-S(=O)-R4-O)N-H
WHEREIN
Y IS AN INTEGER FROM 1 TO ABOUT 50 OR MORE AND N IS AN INTEGER FROM 1 TO 40, R1 IS SELECTED FROM THE GROUP CONSISTING OF (A) ALKYL RADICAL CONTAINING FROM 1 TO 2J CARBON ATOMS, (B) AN ARYL RADICAL (C) AN ARALKYL RADICAL WHEREIN THE ALKYL PORTION OF THE RADICAL CONTAINS FROM 1 TO 4 CARBON ATOMS AND (D) AN ALKARYL RADICAL WHEREIN THE ALKYL PORTION CONTAINS FROM 1 TO 24 CARBON ATOMS, R2 IS ALKYLENE RADICAL HAVING 2 TO 5 CARBON ATOMS, AND R3 AND R4 ARE ALKYLENE RADICALS HAVING 2 TO 5 CARBON ATOMS, A PHENYLENE RADICAL OR A (C1-C4) ALKYL SUBSTITUTED PHENYLENE RADICAL WITH THE PROVISIO THAT N IS 1 WHEN R3 AND R4 ARE PHENYLENE OR (C1-C4) ALKYL SUBSTITUTED PHENYLENE.
Abstract:
CERTAIN MIXTURES OF TETRACHLORODIFLUOROETHANE AND ACETONITRILE ARE USEFUL AS SOLVENTS TO REMOVE ROSIN FLUXES FROM PRINTED CIRCUIT BOARDS. THESE MIXTURES ARE USEFUL BECAUSE OF THEIR UNUSUALLY HIGH SOLVENCY CHARACTERISTICS. A NARROWER CLASS OF SUCH MIXTURES IS PARTICULARLY VALUABLE BECAUSE, IN ADDITION TO HIGH SOLVENCY CHARACTERISTICS, THE MIXTURES EXHIBIT AZEOTROPIC CONSTANT BOILING CHARACTERISTICS, THEREBY FACILITATING HANDLING AND PURIFICATION OF THE SOLVENT MIXTURES WITHOUT SIGNIFICANTLY ALTERING THEIR COMPOSITIONS.
Abstract:
A COMPOSITION IS PREPARED SUITABLE FOR LUBRICATING THE INTERFACE OF LIQUID METAL AND MOLD DURING THE CONTINUOUS CASTING OF METALS. THIS LUBRICATING COMPOSITION CONTAINS AN ALIPHATIC OR AROMATIC CARBOXYLIC ACID HAVING 2 TO ABOUT 40 CARBON ATOMS, E.G., THE ACIDS OBTAINED BY HYDROLYSIS OF AND CONTAINED IN CRAMBE AND RAPESEED OILS AND MIXTURES OF THEM, AND A MINERAL LUBRICATING OIL HAVING A LOW CARBON RESIDUE AND LOW AROMATIC CARBON CONTENT WHICH CAN BE PREPARED BY A TWO-STAGE CATALYTIC HYDROGENATION PROCESS.
