摘要:
Reaction products of hydrocarbylsuccinic anhydrides, hydroxyl-containing amines and triazoles have been found to be effective antirust, antioxidant, anti-corrosion, antiwear, dispersant/detergent and thermal color stabilizing additives.
摘要:
Alkoxylated- or polyalkoxylate-amine-phosphite derived olefin adducts are superior as lubricating fluid media and as multifunctional additives with internal synergistic antioxidant and extreme pressure/antiwear properties for both mineral and synthetic lubricating oils as well as fuels.
摘要:
Reaction products of hydrocarbylsuccinic anhydrides, polyamines and triazoles, as exemplified by XRT 2143A, have been found to be effective rust/corrosion inhibiting, thermal stabilizing and superior dispersant additives with excellent cleanliness feature for fuels and lubricants. Enhanced antioxidancy is also observed upon boration of these reaction products.
摘要:
Cyclic diol- and diol-ester phosphite adducts of olefins and polymeric olefins provide superior multifunctional and lubricating fluid media with internal synergistic multifunctional antiwear, antioxidant properties and extreme pressure/antiwear additives for both mineral and synthetic lubricating oils as well as liquid hydrocarbon fuels.
摘要:
The invention concerns an additive package for a lubricating fluid or grease containing an effective amount of a phosphorus-containing antiwear additive, the improvement comprising the absence of primary, secondary, tertiary, cyclic low molecular weight aliphatic amines with a carbon number of C30 or less.
摘要:
The invention relates to compositions suitable as additive packages for lubricants and other functional fluids, the composition comprising sulfur-containing extreme pressure components, phosphorus-containing anti-wear additives, a triazole-containing species. A preferred use is in industrial gear oils. In embodiments, enhance protection in the areas of bearing wear and micropitting are obtained.
摘要:
Phosphites of hydrocarbyl diols or alkoxylated amines are reacted with aryl sulfonic acids preformed or formed in situ in lubricants to provide multifunctional antioxidant, corrosion inhibiting, and friction reducing properties therefor.
摘要:
The reaction product of diacyl generating species, hydrocarbyl amines and diaryl phosphites are effective EP/antiwear and antioxidant additives in lubricating oils, greases and functional fluids.
摘要:
The invention concerns a fully formulated lubricating fluid or grease comprising an additive package and a major amount of base oil, the improvement comprising the substantial absence of low molecular weight primary, secondary, tertiary, cyclic aliphatic mono or polyamines of 30 carbons or less and the absence of the corresponding acid phosphate amine salts in said fully formulated lubricating fluid.
