Triaole-dialkyl maleate derivatives have been found to be effective metal passivators and antiwear additives for lubricants and fuels.

Triazole-maleate adducts as metal passivators and antiwear additives

Organic triazole-derived carboxylic acid-esters, and ester-amide-amine salts have been found to be effective antiwear additives for lubricants and are highly useful in fuels.

Fuel composition comprising triazole-derived acid-esters or

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

Vinyl pyrrolidinone capped phosphorodithioates have been found to be effective multifunctional antiwear/antioxidant additives for fuel compositions.

Phosphorodithioate-derived pyrrolidinone adducts as multifunctional

A lubricant of fuel composition contains a multifunctional antioxidant/metal deactivating and thermal stabilizing amount of a tolyltriazole-derived Mannich base made from a tolyltriazole, an aliphatic amine, such as diisobutylamine or bis(2-ethylhexyl)amine, a cyclic amine, such as 1,4-diaminocyclohexane or ether amines exemplified by C.sub.6 to C.sub.13 alkoxypropylamines and polyether primary amines such as those derived from nonylphenol ethyoxylates and formaldehyde. The reaction products are, optionally, treated with epoxide.

Multifunctional additives

Organic triazole-derived carboxylic acid-esters, and ester-amide-amine salts have been found to be effective antiwear additives for lubricants.

Lubricant compositions comprising triazole-derived acid-esters or

Vinyl pyrrolidinone capped phosphorodithioates have been found to be effective multifunctional antiwear/antioxidant additives for lubricants.

Non-emulsive lubricant compositions are provided when an additive mixture of a metal-alkylaromatic sulfonate and an alkaline-earth metal alkyl phenate are added in minor effective amounts to lubricant compositions.

Lubricant composition

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

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

Hydraulic fluids containing the reaction product of benzotriazole and tricresyl phosphate are stabilized by the addition thereto of minor amounts of calcium dinonyl naphthalene sulfonate and calcium alkyl phenate. Such fluids and other oleaginous compositions containing the above-described novel additive combination are thus provided with good corrosion control, rust protection and improved cleanliness plus antiwear protection.
