Abstract

Described are novel enaminones of the formula: ##STR1## wherein R is a lower alkyl or oxyalkyl group having 1 to 5 carbon atoms, R₁ is an alkyl group having from 1 to 200 carbon atoms or a similar alkyl group substituted by nitrogen, oxygen or other inert substituents; R₂ is hydrogen or an alkyl group having from 1 to 20 carbon atoms; R₃ is an alkyl or substituted alkyl group having from 1 to 20 carbon atoms. These products are prepared by the reaction of a 1,3-dicarbonyl compound and a primary or secondary amine analog.

In neat or mixed form, the present compounds are useful as dispersants-detergents in oleaginous compositions.

Claims

1. An enaminone reaction product prepared by reacting ethylacetoacetate with an alkenylsuccinimide in the presence of p-toluene sulfonic acid;

said alkenylsuccinimide providing an alkenylsuccinyl moiety represented by the formula ##STR5## in which R₄ is hydrogen or a C₁ -C₁₀₀ alkyl or alkenyl group and n ranges from 1 to 6.

2. An oleaginous lubricating oil composition comprising a major amount of a hydrocarbon and an effective detergent-dispersant amount of the reaction product of claim 1.
