Abstract
SE PRESENTA UN PROCESO PARA LA RECUPERACION DE UN MONOMERO DE UN MATERIAL DE DESECHO MULTICOMPONENTE QUE INCLUYE UN POLIMERO HIDROLIZABLE, EL PROCESO INCLUYE LA PUESTA EN CONTACTO DEL MATERIAL DE DESECHO MULTICOMPONENTE CON AGUA Y LA EXPOSICION DE LA MEZCLA RESULTANTE AL CALOR Y A LA PRESION PARA FORMAR UNA PARTE ACUOSA LIQUIDA QUE PRINCIPALMENTE INCLUYE PRODUCTOS DE DESPOLIMERIZACION DEL POLIMERO HIDROLIZABLE Y UNA PARTE INSOLUBLE EN AGUA QUE PRINCIPALMENTE INCLUYE COMPONENTES DIFERENTES A LOS PRODUCTOS DE LA DESPOLIMERIZACION; LA SEPARACION DE LA PARTE ACUOSA LIQUIDA Y DE LA PARTE INSOLUBLE EN AGUA; LA EXPOSICION DE LA PARTE ACUOSA SEPARADA A UNA PRESION QUE SE INFERIOR A LA DEL PASO A) Y AL CALOR PARA PRODUCIR UN RESIDUO Y UN DESTILADO QUE CONTIENE UN MONOMERO; Y LA SEPARACION DEL MONOMERO EN EL DESTILADO DE OTROS COMPONENTES DEL DESTILADO. EL PROCESO ES PARTICULARMENTE UTIL PARA LA RECUPERACION DE CAPROLACTAMA A PARTIR DE MATERIALES DE DESECHO QUE INCLUYAN NYLON 6.
