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.
