Abstract
Abstract Compositions are obtained by halogenating an alkenyl succinic acid or acid derivative in a hydroxylic solvent and treating the resulting product under dehydrating conditions with an amine. The products with relatively long hydrocarbon chains find use as detergents in lubricating oils and as emulsifiers.
