Abstract

UN METODO DE RECUPERACION DE FENOL DIHIDRICO, PARTICULARMENTE BISFENOL RESIDUO DE REACCION DE UNIDADES DE BISFENOL A. GRANULAR EL POLIMERO QUE CONTIENE BISFENOL AS PARTICULAS CON UN ALCOHOL, O CUALQUIER OTRO DISOLVENTE ORGANICO DE HINCHADO MISCIBLE CON AGUA Y FACILMENTE DESTILABLE DE UNA DISOLUCION ACUOSA, PREFERIBLEMENTE UN ALCOHOL C{SUB,1} {SUB,10}, DURANTE UN TIEMPO SUFICIENTE PARA HINCHAR LAS PARTICULAS; C. PONER EN CONTACTO LAS PARTICULAS HINCHADAS CON UNA DISOLUCION AMONIACAL A UNA TEMPERATURA DE POR LO MENOS UNOS 25 (GRADOS) C DEPENDIENDO DEL DISOLVENTE DE HINCHADO UTILIZADO PARA CORTAR SELECTIVAMENTE LOS ENLACES ESTER DE LAS UNIDADES DE BISFENOL A; D. SEPARAR LA FASE LIQUIDA DE LA FASE SOLIDA; E. DESTILAR EL AMONIACO Y EL DISOLVENTE DE HINCHADO DE LA FASE LIQUIDA DEL APARTADO D. ANTERIOR, PARA OBTENER ASI ESENCIALMENTE UNA DISOLUCION ACUOSA CON UREA DISUELTA Y BISFENOL TE PRECIPITADO; F. AÑADIR AL RESIDUO DEL APARTADO E. ANTERIOR AGUA EN CANTIDAD SUFICIENTE PARA PRECIPITAR EL BISFENOL RA DE ESTE MODO FORMAR UNA FASE LIQUIDA Y UNA FASE SOLIDA; G. RECUPERAR LA FASE SOLIDA DE BISFENOL OL A FORMAR PARTE DE LA DISOLUCION EN EL APARTADO F. ANTERIOR. LA UREA ES, POR LO TANTO, TAMBIEN RECUPERABLE Y PUEDE SER UTILIZADA COMO TAL O DEGRADADA HASTA SUS PARTES COMPONENTES TALES COMO DIOXIDO DE CARBONO Y AMONIACO, PUDIENDO EL AMONIACO SER TAMBIEN REUTILIZADO EN ESTE PROCESO AMONIACAL.
