The invention provides a lubricating composition containing an oil of lubricating viscosity and an ashless thiocarbamate compound having an optionally-substituted hydrocarbyl group on an S-atom and an optionally-substituted hydrocarbyl group on an N-atom. The invention further relates to a method of the lubricating an internal combustion engine with the lubricating composition.

Lubricating composition containing a thiocarbamate compound

The invention provides a lubricating composition containing an oil of lubricating viscosity and a nitrile compound. The invention further relates to a method of the lubricating an internal combustion engine with the lubricating composition.

Lubricating composition containing an antiwear agent

The present invention provides a low cost technique for synthesizing substituted trithiocarbonates and derivates thereof, by a one-step process which does not require solvent washes or re-crystallization steps, and results in practical yields more than double that of processes disclosed in the prior art.

Process for making substituted trithiocarbonate derivatives

Hydrocarbyl substituted carboxylic compositions and derivatives thereof useful as additives for lubricating oil and fuel compositions. Carboxylic composition are derived from (A) an olefinically unsaturated hydrocarbon, said hydrocarbon having at least one allylic hydrogen atom, and (B) an &#x3b1;,&#x3b2;-unsaturated carboxylic compound prepared by reacting

Lubricating oil additives

Compositions comprising reaction product of higher molecular weight olefinic reactants with carboxylic reactants of the formula R.sup.3 C(O)(R.sup.4).sub.n C(O)OR.sup.5 (IV) or the corresponding acetals, hemiacetals, ketals, and hemiketals thereof are useful as intermediates for further reaction in the preparation of lubricating oil additives.

Intermediates useful for preparing dispersant-viscosity improvers for

This invention relates to a composition, comprising:

Mixed polysulfides and lubricants and functional fluids containing the

Substituted carboxylic acylating agents formed by reacting an olefin with a carboxylic reactant are further reacted with .alpha.-.beta. unsaturated carboxylic compositions to form substituted carboxylic acylating agents. The substituted carboxylic acylating agents are further reacted with various compounds to form especially dispersants for use in oil compositions.

Substituted carboxylic acylating agent compositions and derivatives

Polyalkylene substituted carboxylic acylating agents which contain chlorine are synthesized by chlorine induced condensation of polyalkylenes and .alpha.-.beta. unsaturated carboxylic groups are treated with sulfur to reduce chlorine content of the carboxylic acylating agent.

Low chlorine polyalkylene substituted carboxylic acylating agent

The present invention deals with stabilizing triglyceride oils of high oleic content through the use of tocopherol. This combination of the high oleic oil and the tocopherol results in a surprisingly stable composition for use in deep frying.

Vegetable oil compositions

Polymers of pyrrole or copolymers of pyrrole are obtained having high surface area and low conductivity. Such polymers and copolymers are useful in forming catalysts.

High surface area polymers of pyrrole or copolymers of pyrrole

A mixture of metal salts of aromatic/aliphatic phosphorodithioic acids is disclosed. The metal salts, a mixture of the aromatic/aliphatic phosphorodithioic acids contain an aliphatic group and an aromatic group, optionally (H) aliphatic groups, and optionally (B) aromatic groups. The (B) aromatic component can be made utilizing phenol and/or mixtures of cresylic acids. The metal salts are oil-soluble and are useful as corrosion inhibitors and anti-wear agents, particularly in lubricating oil compositions.

Metal salts of mixed aromatic/aliphatic phosphorodithioic acids

The present invention describes devices capable of sensing changes of acidity in a non-aqueous medium. The devices are particularly useful for determining the alkaline reserve in a motor vehicle lubricating oil.

Acid sensor

Basic metal dihydrocarbylphosphorodithioates and phosphoromonothioates are prepared by employing a catalytic amount of an alkali metal or alkaline earth metal hydroxide or mixtures thereof. Also basic, multiple metal complexes of various dihydrocarbylphosphorodithioic acids have been developed. These salts and complexes are highly effective antiwear and antioxidant additives for functional fluids, e.g., lubricating oils.
