Abstract
Det beskrives nitrogen-lnneholdende karboksy Ilske forbindelser som er nyttige l å redusere hydrogen- sulfid. Forbindelsene omfatter (A) en olje med smørende viskositet; (B) reaksjonsproduktet av minst en poly-karboksyllske forbindelse som har minst en hydrokarbon-basert substltuent fra 10 til 500 karbonatomer med minst en av: (i) en N-(hydroksyl-substltuert hydrokarbyl )amln eller (11) et hydroksyl-substituert poly(hydrokarbyl- oksy) derivat av nevnte amln; (C) en aktiv svovel-lnneholdende organisk forbindelse; °g (D) minst en alkallmetall- eller Jordalkallmetall inne- holdende forbindelse. Den beskrevne smøreoljesanunensetningen er særlig effektiv i skjærevæsker der den har evne til å redusere dannelse av hydrogensulfid.Nitrogen-containing carboxylic acid compounds are described which are useful in reducing hydrogen sulfide. The compounds comprise (A) an oil of lubricating viscosity; (B) the reaction product of at least one polycarboxylic acid having at least one hydrocarbon-based substituent from 10 to 500 carbon atoms with at least one of: (i) an N- (hydroxyl-substituted hydrocarbyl) amine or (11) a hydroxyl-substituted poly (hydrocarbyl oxy) derivatives of said amine; (C) an active sulfur-containing organic compound; ° g (D) at least one alkali metal or alkaline earth metal containing compound. The lubricating oil anion composition described is particularly effective in cutting fluids where it has the ability to reduce hydrogen sulfide formation.
