摘要:
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.
摘要:
A system for treatment of exhaust emissions from a compression-ignited internal combustion engine comprises (A) a superatmospheric-pressurized source of gaseous oxygen, (B) an inlet for the gaseous oxygen of component (A) where the exhaust emissions from the engine flow past the inlet and form a mixture with the gaseous oxygen from the inlet, and (C) a diesel particulate filter or catalyzed diesel particulate filter through which the mixture of engine exhaust emissions and gaseous oxygen flows, where the oxygen content of the mixture is greater than the oxygen content of the exhaust emissions from the engine. A method for improving the performance of a diesel particulate filter or catalyzed diesel particulate filter in a compression-ignited internal combustion engine comprises operating the engine and treating the exhaust emissions from the engine with the exhaust emissions treatment system.

摘要:
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.
摘要:
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.
摘要:
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.

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.
摘要:
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.
