Abstract

PROCEDIMIENTO PARA LA MICROENCAPSULACION DE DISOLUCIONES ACUOSAS DE AMINAS. CONSISTE EN EMULSIONAR UNA DISOLUCION ACUOSA DE AMINAS EN UN LIQUIDO ORGANICO; SEGUIDO DE LA FORMACION DE UNA MEMBRANA POLIMERICA EN TORNO A LAS GOTITAS DE LA EMULSION MEDIANTE POLIMERIZACION INTERFACIAL POR REACCION CON UN CLORURO DE ACIDO O ANHIDRIDO POLIBASICO Y FINALIZACION DE LA POLIMERIZACION AL INTRODUCIR EN EL MEDIO AGUA DISUELTA EN UN ALCOHOL ALIFATICO C<1<-<5. TIENE APLICACIONES PARA EL ENCAPSULADO DE LIQUIDOS HIDROFILOS EN UNA FASE CONTINUA HIDROFOBA.
