Alkoxy borates of alkylated phenols have been found to be effective cleanliness agents for lubricants and additives for improving the dropping point of greases.

Complex alkoxy borates of alkylated phenols as lubricant stabilizers

The reaction product of olefin, sulfur, aliphatic amine, alkylene oxide, phosphorus pentasulfide, and phosphorus pentoxide provides an effective antiwear additive agent for lubricating oils.

Reaction products of olefins, sulfur, aliphatic amine, alkylene oxide,

Mixtures of borated alcohols are effective friction modifying additives when incorporated into various lubricating or fuel media.

Friction reducing additives and compositions thereof

Borated glycerol hydroxyesters are effective friction reducing additives when incorporated into lubricating compositions.

An additive for fuel compositions. The additive comprises the reaction product of an alkenyl succinimide selected from the group consisting of mono-succinimides, bis-succinimides, and mixtures thereof, with iminodiacetic acid or an ethylenediamine carboxy acid. The reaction product finds particular utility as a fuel detergent.

Reaction products of alkenyl succinimides with ethylenediamine carboxy

An olefin when reacted with sulfur and phosphorus pentasulfide provides an effective antiwear additive agent for lubricant oils.

Reaction products of olefins, sulfur and phosphorus pentasulfide and

Products made by reacting an alkenylsuccinic compound with an arylamine and a hindered alcohol provide superior dispersant and antioxidant activity to lubricant compositions when incorporated therein.

Reaction products of alkenylsuccinic compounds with aromatic amines and

Benzophenone derivatives, e.g., benzophenone tetracarboxylic dianhydride, and esters or mixtures thereof when reacted with various hydrocarbyl amines provide additives that are highly useful as fuel detergents, intake valve and exhaust gas valve deposit reducers.

Benzophenone derivatives as fuel additives

Products made by reacting (i) an alkenylsuccinic compound with (ii) an arylamine and (iii) an alkanolamine, an aminomethane or a hindered alcohol and borated reaction products thereof which provide superior dispersant and antioxidant activity to lubricant compositions when incorporated therein.

Borated reaction products of alkenyl succinic compounds, aryl amines and aminoalcohols are highly effective dispersant and antioxidant/anticorrosion additives for lubricant compositions.

Borated reaction products of succinic compounds as lubricant dispersants

It has been found that products made by reacting a polyalkenylsuccinic compound with an aromatic secondary amine or hindered phenol containing a hydroxyalkyl group, followed by reaction with an alkanolamine or an aminomethane, give a novel additive having utility as a dispersant and/or an anticorrosion agent when placed in a lubricant.

Products of reaction involving alkenylsuccinic anhydrides with

The invention herein is concerned with novel compositions of matter made by reacting phosphorus pentasulfide with a polyhydroxyester and then followed by reaction with a salt-forming metal-containing compound and lubricant compositions containing same.

Metal salts of phosphosulfurized polyhydroxyesters and lubricants

A fuel composition comprising a liquid hydrocarbon fuel and a detergent amount of the product of reaction between a polyamine and a stearic acid is described.

Liquid hydrocarbon fuel composition

A lubricant concentrate for use in metal processing comprises a sulfur compound such as a sulfurized olefin or sulfurized mineral oil and an ester prepared from a fatty acid having 12 to 40 carbon atoms or the dimer thereof or a polyalkenylsuccinic acid or anhydride and a hydroxyl-containing amine.
