Abstract

PROCEDIMIENTO PARA LA ELABORACION DE LOS RESIDUOS, EN FORMA DE ESCORIAS, DE LA DESTILACION DE TOLUILENDISOCIANATOS DESNATURALIZADOS CON AGUA. SE MEZCLAN, EN UN APARATO AGITADOR, PARTICULAS DE TAMAÑO INFERIOR A 0,2 MILIMETROS DE ESCORIA DE RESIDUO DE TOLUILNDIISOCIANATOS DESNATURALIZADA, CON UN ALCOHOL DIVALENTE Y/O TRIVALENTE DE PESO MOLECULAR ENTRE 62 Y 200, COMO ETILEN-O DIETILENGLICOL, CALENTANDOSE LA SUSPENSION ENTRE 100 G- 200 GC PARA INICIAR LA REACCION DE LINEALIZACION. SE EFECTUA POSTERIORMENTE UN CALENTAMIENTO RAPIDO ENTRE 150G-180GC HASTA QUE LA MEZCLA SE HAGA HOMOGENEA. SE INTERRUMPE LA REACCION POR ENFRIAMIENTO Y SE ELIMINA EL ALCOHOL EN EXCESO POR DESTILACION A TEMPERATURAS INFERIORES A 130 GC O POR LAVADO CON AGUA. SE UTILIZAN COMO MATERIA PRIMA LA OBTENCION DE MATERIALES SINTETICOS, COMO RECUBRIMIENTOS, LACAS O AGENTES DE ENCALADO, O SE RECICLAN POR HIDROLISIS A LAS TOLUILENDIAMINAS EMPLEADAS EN LA OBTENCION DE LOS TOLUILENDIISOCIANATOS. *FORMULA*
