Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to additive compositions for use in lubricants and normally liquid fuels. For fireflies, the present invention relates to additive compositions derived from the interaction of unsubstituted succinic acylating agents or aliphatic hydrocarbon bulk group-substituted acylating agents and needle amines, concentrates thereof, and additive compositions thereof. lubricants and normally liquid fuels containing the same.

Lubricants and normally liquid fuels are known to corrode various materials with which they come into contact.

For example, normally liquid fuels accumulate large amounts of water during storage and, when they later come into contact with metal surfaces in the environment in which they function, cause rust and corrosion to occur.

Water is known to be a common contaminant in engine crankcase lubricants.

Water can form from the oxidation of lubricating oils or exit the combustion chamber as a blow byproduct of burning fuel. The presence of this water, in addition to causing rust and corrosion, appears to promote the deposition of mayonnaise-like sludge. This type of sludge is very persistent in that it adheres tenaciously to metal surfaces and cannot be removed by filtration.

To overcome the corrosivity of lubricants and fuels, which are usually liquid, and to improve the dispersion properties of lubricants, it is common practice to add corrosion inhibitors and dispersants to lubricants and fuels. Many materials have been developed for this purpose. for example,
Mono- and dicresyl phos-7ate [dacillin salt (
U.S. Pat. No. 3,738,110), hot metal products of alkyl or -alkenyl succinic acids and N-aminoalkyl- or N-hydroxyalkyl-substituted imidacillin salts of alkyl or alkenyl succinic acids (U.S. Pat.
