Abstract:
Additives which improve the low-temperature properties of distillate fuels are the reaction products of (1) diols, and (2) the product of pyromellitic dianhydride and combinations of two or more different aminoalcohols with long-chain hydrocarbyl groups attached.
Abstract:
Reaction products, in which aromatic acid bis(polyether ester) is added to succinimides, are effective antioxidants, dispersants, and detergents for fuels and lubricants.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are the reaction products of (1) diaminodiols, and (2) the product of pyromellitic dianhydride and aminoalcohols and/or amines with long-chain hydrocarbyl groups attached.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are oligomeric/polymeric reaction products of anhydrides and long-chain epoxides (or their corresponding acid/diol equivalents) consisting of hydroxyl promoted polyesters and ester promoted polyesters.
Abstract:
Lubricating oil and grease compositions contain borated hydroxyalkyl esters of amine or metal salts of diorganodithiocarbamic acid, such as N,N'-di-(2-ethylhexyl) dithiocarbamic acid, and hydrocarbylene oxie, such as propylene oxide, as antioxidant, load-carrying and friction modifying additives.
Abstract:
Products derived from the reaction of organic or metal salts of diorganodithiocarbamic acids with benzenesulfonyl halides, impart excellent multifunctional antiwear and antioxidant properties to lubricating oil compositions.
Abstract:
A lubricant or fuel composition contains a major portion of a lubricant or fuel and a minor portion of an additive composition which is the reaction product of long chain epoxides and polyamines such as polyethyleneamines.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are the reaction products of (1) diaminodiols, and (2) the product of benzophenone tetracarboxylic dianhydride and aminoalcohols and/or amines with long-chain hydrocarbyl groups attached.
Abstract:
Disclosed is an additive for lubricant or fuel compositions comprising the boronated reaction product of polyalkenyl-substituted succinimides, aldehydes and triazoles.
Abstract:
Disclosed is an additive for liquid hydrocarbon fuel composition, particularly diesel fuels. The additive composition is the reaction product of polyalkenyl-substituted succinimides, aldehydes, and triazoles. It also finds use in lubricant compositions.
