Mannich bases, prepared using a phenol substituted with a medium length branched alkyl chain, the alkyl being derived from a 1-olefin oligomer. These Mannich bases act as friction-reducing agents in lubricant and liquid fuel compositions.

Mannich base oil additives

A borated oxazoline monoester, made by reacting a boron compound with the product of reaction between tris(hydroxymethyl)aminomethane and carboxylic acid is a new composition of matter. It is useful in a lubricating oil for reducing friction, and, therefore, fuel consumption in an internal combustion engine.

Lubricant composition

Reaction products of N-alkylalkylenediamine with organic acids are disclosed.

N-alkoxyalkylenediamine [organic acid reaction products] diamides and

Mercaptothiadiazole adducts of unsaturated esters such as jojoba oil or pentaerythritol tetraoleate are highly effective multifunctional friction reducing and copper strip passivating additives for various lubricants.

Multifunctional lubricant additives and compositions thereof

Amides of certain ether diamines are provided. These compounds give excellent results when tested in lubricants as friction reducing additives.

N-Alkoxyalkylenediamine diamides and lubricants containing same

Lubricant and fuel compositions having unique fuel saving properties are obtained by adding to the lubricant or fuel a product made by reacting a boron compound with a mixture of vicinal diols and long chain alcohols or hydroxyl-containing carboxylate esters.

Mixed borate esters and their use as lubricant and fuel additives

High quality synthetic lubricating oils are provided when certain olefinic monomers such as ethylene, propylene and a third 1-olefin are copolymerized and thereafter dewaxed by means of a urea adduction process.

Process for making synthetic lubricating oils

Reaction products from thiodephenol, aldehydes and amines are effective friction reducing additives in lubricants.

Sulfur-containing mannich bases and lubricants containing same

Reaction products from certain phenol, aldehydes and amines are effective friction reducing additives in lubricants and in liquid fuels, such as gasoline and alcohol fuels.

Phenolic-containing mannich bases and lubricants containing same

Dimercaptothiadiazole adducts of hydroxyl-containing unsaturated compounds and their borated analogues provide effective multifunctional friction reducing and corrosion inhibiting properties to various lubricating fluids when incorporated therein.

Metal salts of hydrocarbyl oxazoline phosphorodithioic acids are novel compounds effective for reducing friction and wear when added to a lubricant.

Phosphorus-containing compounds and lubricants containing same

Phosphosulfurized hydrocarbyl oxazoline reacted with nitrogen-containing compounds and certain olefins are novel compounds effective for reducing friction and wear when added to a lubricant.
