Abstract: This invention provides a process for and products of the Mannich condensation reaction of oxidized olefinic polymers. The Mannich reaction is carried out in the presence of about 0.01 to 40.0% by weight of an oil soluble sulfonic acid based on the neat polymer. The sulfonic acid improves the properties of the oxidized oil soluble Mannich reaction product and catalyzes the Mannich condensation reaction.
Abstract: An improved lubricant composition comprises (A) a lubricant mineral oil base, (B) a Mannich condensation reaction product comprising the reaction product of an alkyl phenol, a polyamine and formaldehyde, (C) an alkaline earth metal salt of a Mannich condensation reaction product comprising the reaction product of alkyl phenol, formaldehyde and a polyamine, (D) an alkylbenzene alkaline earth metal sulfonate of low total base number, and (E) the alkaline earth metal salts of a bis-alkylphenol sulfide, (F) chlorinated paraffin, and (G) dimethyl siloxane polymer.

Abstract: Materials of the general formula MXY.sub.3 wherein M is selected from the group consisting of Mg, V, Mn, Fe, Co, Ni, Zn, Cd, Sn, Pb and mixtures thereof; X is a pnictide selected from the group consisting of phosphorus, arsenic, antimony, and mixtures thereof, and Y is a chalcogenide selected from the group consisting of sulfur, selenium and mixtures thereof, have been discovered to be superior lubricants exhibiting resistance to oxidation and thermal degradation, low friction, excellent antiwear activity and long effective life. Metal surfaces coated with such materials resist gauling and damage due to adhesive or corrosive wear. These materials can be used as dry solid lubricants or as additives to oils and greases.
Abstract: A machining fluid includes a basic component in the form of an aqueous solution and an aliphatic acid organic compound which is produced by a fermentation process comprising cultivating a microorganism in a culture medium containing a saccharide, nitrogen source and an inorganic salt and accumulated in a culture broth and separated and recovered from the culture broth.
Abstract: Synthetic lubricating oil compositions comprising a unique combination of additives. A variety of esters known in the prior art to be useful in synthetic lubricating compositions for aircraft engines may be used in the compositions of this invention. Esters derived from neopentyl polyols are, however, preferred and best results are obtained when the esters are derived from a mixture of such polyols. The additive combination comprises, essentially, an oil-soluble organic amine salt of a phosphate ester and a neutral oil-soluble organosulfonic acid ammonium salt. The additive combination is particularly effective in increasing the load carrying ability of lubricating oils, which especially is critical in applications such as turbine engines.

Abstract: Compositions made by reacting (I) a metal phenoxide substituted with at least one hydrocarbon-based group of at least about 30 carbon atoms with (II) a carboxylic acid reagent containing from one to three carboxyl-based groups and a halogen-substituted hydrocarbon-based aliphatic or alicyclic group containing a halogen atom are useful as additives for lubricants and normally liquid fuels. Analogous thiophenoxide-based compositions are similarly useful. These compositions are also useful as intermediates for the preparation of other useful additive compositions through their reaction with alcohols, amino compounds, reactive small ring heterocycles and basically reacting metal compounds.

Abstract: A coating bath containing sodium and/or potassium silicate is stabilized and its useful life prolonged by the additions of sodium or potassium hydroxide in amounts at least substantially equal to that required to compensate for the amounts of CO.sub.2 or CO.sub.3 anions introduced into the bath which, in reacting with the hydroxide formed by the hydrolysis of the silicate to form carbonates, upsets the hydrolysis equilibrium leading to further hydrolysis of the silicate. Similarly, a quantity of hydroxide is added to compensate substantially for other reactive species which significantly affect the hydrolysis equilibrium of the silicate.

Abstract: A stable free sulfur containing mineral oil is produced in a two-step process. The first step of the process comprises producing a sulfurized solubilizing oil by reacting a lubricant oil with elemental sulfur until the uncombined sulfur content is less than about 0.5%. The second step comprising dissolving in the oil a quantity of sulfur such that the final concentration of uncombined sulfur is less than 2.0%.

Preferred polymerizable ethylenically unsaturated nitrogen-containing compounds are those selected from the group consisting of 2- and 4-vinylpyridines and N-vinyl-2-pyrrolidinones.
Abstract: An improved method for preparing clay-based grease compositions is described whereby a clay containing pre-grease is prepared and a water phase separated from the clay-bearing pre-grease prior to the addition of an epoxide which is cured, e.g., simultaneously with the dehydration of the pre-grease. The grease compositions prepared in this manner show improved water resistance over those wherein the epoxide is added prior to separation of the water phase and the grease is also more responsive to the addition of conventional grease additives such as extreme pressure additives, anti-corrosion additives and anti-oxidants.
