Abstract

Se preparan lactamas de acilo de alta calidad haciendo reaccionar una lactama, un anhídrido de un ácido carboxílico y un ácido acilante, preferiblemente en presencia de un catalizador básico; el procedimiento produce lactamas de acilo en alto rendimiento y a temperaturas de reaccion más bajas; las lactamas de acilo son particularmente adecuadas para usarse como activadores de blanqueo en composiciones detergentes.
