A TOW-STEP PROCESS FOR PREPARING A HIGH TEMPERATURE GREASE IS PROVIDED, IN WHICH A THICKENING AGENT IS FIRST FORMED, IN THE FIRST STEP, BY NEUTRALIZING A LOWER ALKYL ESTER OF A HYDROXY FATTY MONOCARBOXYLIC ACID WITH AN EXCESS OF A METAL BASE SELECTED FROM THE GTOUP CONSISTING OF ALKALI METAL BASES AND ALKALINE EARTH METAL BASES IN AN OIL VEHICLE. THE REACTION IS CONDUCTED AT ELEVATED TEMPERATURE IN THE RANGE OF 300* TO 400*F. IN A CLOSD SYSTEM. IN THE SECOND STEP, AN ALKYL ESTER OF AN ALIPHATIC DICARBOXYLIC ACID IS ADDED TO THE SOAP-THICKENED OIL COMPOSITION OF STEP ONE. THE MIXTURE THUS FORMED IS HEATED TO A TEMPERATURE IN THE RANGE OF 350* F. TO 450* F. IN A CLOSED SYSTEM.
摘要:
Compositions useful to improve power transmission in automatic transmission fluids, hydraulic fluids and the like as replacements for basic barium salts of sperm oil are obtained by reacting an excess of a barium base with the combination of a phenol (preferably an alkylphenol), a fatty acid and an alcohol, wherein the fatty acid and alcohol together contain at least 26 carbon atoms in straight-chain configuration. The compositions are preferably further reacted with carbon dioxide, and they may additionally be reacted with about 1-5% of anthranilic acid.

SOLID, GROUPS I AND II METAL-CONTAINING MICELLAR COMPLEXES ARE PREPARED BY ISOLATING THE SOLID, METAL-CONTAINING MATTER FROM HOMOGENIZED, OVERBASED ORGANIC ACIDS WITH THE AID OF SUCH CONVERSION AGENTS AS ALIPHATIC CARBOXYLIC ACIDS, WATER, ALCOHOLS, PHENOLS, KETONES, ALDEHYDES, AMINES, BORON ACIDS, PHOSPHORUS ACIDS, OXYGEN, AIRCARBON DIOXIDE, AND MIXTURES THEREOF. THE METAL-CONTAINING COMPOSITIONS ARE READILY AND STABLY DISPERSED IN NONPOLAR ORGANIC LIQUIDS. THEY ARE USEFUL AS ADDITIVES IN PLASTICS, RUBBERS, PAINTS, CAULKS, ETC., WHERE THEY FUNCTION AS FILLERS AND THIXOTROPIC AGENTS.

A PETROLEUM DISTILLATE IS IMPARTED WITH A DISTINCT COLORIZATION BY A LIQUID AZO DYE COMPOSITION SOLUBLE IN THE DISTILLATE. THE LIQUID AZO DYE COMPOSITION IS CHARACTERIZED IN THAT IT (A) HAS A COLOR VALUE WHICH IS AT LEAST ABOUT FORTY PERCENT OF THE COLOR VALUE OF A COMPARABLE SOLID DYE; (B) EXHIBITS PERMANENTLY HOMOGENEOUS LIQUIDITY; (C) IS CAPABLE OF COMPLETE AND SUBSTANTIALLY INSTANTANEOUS SOLUBILITY IN PETROLEUM DISTILLATES; AND (D) ESSENTIALLY CONSISTS OF BETWEEN ABOUT 50-75% BY WEIGHT OF A MIXTURE OF AZO DYES CONTAINING C5-C12 ALKYL BETA-NAPHTHOLS OR P-C5-C12 ALKYL PHENOL IN THE DYE MOLECULE AND ABOUT BETWEEN 50-25% BY WEIGHT OF A LIQUID ORGANIC VISCOSITY DEPRESSANT COMPATIBLE WITH THE AZO DYES.

Disclosed are improved lubricants particularly useful for forming metallic articles into desired sizes and shapes based upon operations enhanceable by lubricants. Typical specific working operations are cutting, sawing, grinding, shaping, planing, stamping, drawing, sanding, filing, milling, shearing, machining, and drilling. Preferred lubricant compositions are alkanol mixtures of predominantly normal alcohol and branched primary alcohol structures having predominantly from about 20 to about 34 carbon atoms per molecule, with or most preferably, without other alcohols containing secondary hydroxyl groups or unsaturation ranging from about 14 to about 50 carbon atoms per molecule. The preferred lubricant compositions are characterized by useful residual or film properties for protection of surfaces, particularly those freshly exposed through working when using the lubricants. Such properties are enhanced by the combination of polar and non-polar aspects of the preferred molecules.
