摘要:
Dimercaptothiadiazole reacted with arylsulfonic acids preformed or formed in situ in lubricants provide multifunctional antioxidant, antiwear, and corrosion inhibiting properties thereto.
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:
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:
Disclosed are lubricant compositions containing a lubricant and: (a) the reaction product of a non-metallic dihydrocarbylaromatic or monohydrocarbylaromatic sulfonate and a dialkyl or trialkyl phosphite; or (b) the reaction product of a non-metallic dialkylnaphthalene sulfonate and a dialkyl or trialkyl phosphite and further containing an acid or acid supplying component; or (c) an unreacted mixture of dialkylnaphthalene sulfonic acid and a dialkyl or trialkyl phosphite.
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:
Reaction products of aryltriazoles or arylamines and arylsulfonic acids pre-reacted or formed in-situ in lubricants provide multifunctional antioxidant, antiwear and corrosion-inhibiting properties thereto.
摘要:
Hydrocarbyl thiophosphoric acid-phosphite derived olefin and polymeric olefin adducts are superior as lubricating fluid media with internal synergistic multifunctional antiwear, antioxidant properties, and as multifunctional extreme pressure/antiwear additives for both mineral and synthetic lubricating oils as well as fuels.
摘要:
A urethane reaction product, derived from an alkoxylated diorgano phosphorodithioate and an isocyanate, specifically, toluenediisocyanate and hexamethylene diisocyanate, is a multifunctional antiwear and antioxidant additive for lubricants. The isocyanate groups of the reaction product are substantially converted to urethane and/or urea groups through post reaction with active hydrogen compounds such as dibutylamine, bis(2-hydroxethyl) cocoamine and alcohols such as 2-propanol.
摘要:
Amine salts of sulfur-containing alkylated phenols or alkylated naphthols, have been found to be effective multifunctional antioxidant and antiwear additives for lubricants.
