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.

Amide/ester heterocyclic derivatives of hydrocarbylsuccinic anhydrides

Reaction products, in which aromatic acid bis(polyether ester) is added to succinimides, are effective antioxidants, dispersants, and detergents for fuels and lubricants.

Modified succinimides as dispersants and detergents and lubricant and

Reaction products of hydrocarbylcarboxylic anhydrides and aminoalkanols can provide effective antiwear, antirust, and corrosion-inhibiting properties in lubricant and fuel applications.

Carboxylic acid/ester products as multifunctional additives for

Reaction products in which polyethers are connected to hydroxyalkylated polyamines using diisocyanates have been found to be effective ashless dispersants and detergents for various lubricants and fuels.

Diisocyanate derivatives as lubricant and fuel additives and

Arylamine/hindered phenol, acid anhydride and thioester-derived reaction products, have been found to be effective multifunctional antioxidant, antiwear and rust inhibiting additives for lubricants and fuels.

Arylamine/hindered phenol, acid anhydride and thioester-derived

Reaction products which provide antioxidant properties to lubricants and fuels while serving as effective dispersants and detergents in these mediums. These products, of the reaction of a hydroxyalkylene substituted polyamines and substituted succinic anhydrides, contain mixtures of esters, amides and imides. Furthermore, preferred embodiments of the reaction products have pendent alcohol groups which provide extra dispersancy and detergency over traditional dispersants which typically do not have alcohol groups.

Polymer modified hydroxyalkylene substituted polyamines as lubricant and

The present invention discloses superior fuel and lubricant additives prepared by the acylation of alkyl or alkenyl succinimides with the polyether half-esters of dicarboxylic acids. The polyether half-esters of dicarboxylic acids are grafted onto the polyamine moiety of alkyl or alkenyl succinimides by reacting the succinimide and the half-ester of the dicarboxylic acid under amidation conditions to form an amide group with an amino group of the polyamine. The process is carried out by first reacting a monofunctional polyalkylene ether with a dicarboxylic acid to produce a half-ester of the dicarboxylic acid. This product is then reacted with an alkyl or alkenyl succinimide polyamine ashless dispersant to product a multifunctional hydrocarbon fuel or lubricant additive that exhibits augmented dispersant properties.

Fuel and lube additives from polyether derivatives of polyamine alkenyl

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.

Lubricant composition comprising an octadecylene oxide polyamine

Reaction products in which polyethers are connected to polyamines using diisocyanates have been found to be effective ashless dispersants and detergents for various oils of lubricating viscosity.

Diisocyanate derivatives as ashless dispersants and detergents and

Disclosed is an additive for lubricant or fuel composition comprising the boronated reaction product of polyalkenyl-substituted succinimides, aldehydes and triazoles.

Borated triazole-substituted polyalkenyl succinimides as multifunctional

Reaction products in which polyethers are grown from substituted phenol-containing mannich bases have been found to be effective ashless dispersants and detergents for fuels and lubricants.
