The invention provides a lubricating composition containing an oil of lubricating viscosity, a compound derived from the hydroxy-carboxylic acid and a nitrile compound. The invention further relates to a method of the lubricating an internal combustion engine with the lubricating composition.
摘要:
The present invention provides compositions that are useful for compatabilizing a conventional, non-polar, compression refrigeration lubricant and a hydrofluorocarbon and/or hydrochlorofluorocarbon refrigerant in a compression refrigeration apparatus. Additionally, these composition promote efficeint return of lubricant from the non-compressor zones to the compressor zones of the aforesaid refrigeration apparatus.

摘要:
A universal additive for fuel and lubricants contains C2-C4 alcohols, carbamide, boric acid, acrylic compounds, and water. The additive allows for more complete combustion of liquid and solid fuels, as well as reduced fuel consumption and fewer harmful emissions. In lubricating oil compositions, the additive reduces wear on the friction surfaces of engines, and also reduces fuel consumption.
摘要:
Provided is a lubricant base stock, a lubricating oil including the lubricant base stock and a method for improving viscosity temperature performance or viscosity index of an engine or other mechanical component lubricated with the lubricating oil. The lubricant base stock includes one or more liquid crystals represented by the formula: R1-(A)m-Y—(B)n—R2 wherein R1 and R2 are the same or different and are a substituted or unsubstituted, alkyl or alkoxy group having from 0 to 24 carbon atoms; A and B are the same or different and are a cycloaliphatic group or aromatic group, provided at least one of A and B is an aromatic group; Y is a covalent bond, —CH2-CH2-, —CH═CH—, —C≡C—, —OCOO—, —COO—, —CO—, —CSO—, —CSS—, —CS—, —O—, —S—, —SO—, —SO2-, —CH2O—, —OCH2O—, —NO—, —ONO2, —COOH, —OH, or —C≡N; and m and n are independently 0, 1, 2 or 3. The lubricant base stock has a kinematic viscosity of 2 cSt to 28 cSt at 40° C., and 1 cSt to 12 cSt at 100° C.
摘要:
A bactericide is added to conventional water-soluble cutting fluids to suppress deterioration by microorganisms. Such fluids are however accompanied by the drawbacks that the bactericide has a narrow antibacterial spectrum and moreover its effects last a short time. It is the object of the present invention to offers water-soluble cutting fluids which remain resistant to a wide variety of microorganisms for a long time. The present invention therefore offers water-soluble cutting fluids to which has been added a specific amine selected from amines known to date.
摘要:
Hydraulic fluids having high wet equilibrium reflux boiling points, good chemical stability and other desirable characteristics are made from certain cyano-substituted derivatives of cyclic ketals or acetals of the formula ##STR1## wherein A, B and R are specified radicals.
