Abstract
UN PROCEDIMIENTO PARA REDUCIR LAS IMPUREZAS DE METILBENZOFURANO (MBF) EN FENOL, OBTENIDO A PARTIR DEL PRODUCTO DE DESCOMPOSICION DEL HIDROPEROXIDO DE CUMENO, QUE REQUIERE TRATAR EL FENOL PARA REDUCIR EL NIVEL DE ACETOL, PONER EN CONTACTO EL FENOL QUE CONTIENE UN BAJO NIVEL DE ACETOL CON UNA RESINA ACIDA, A UNA TEMPERATURA Y DURANTE UNA TIEMPO DE RESIDENCIA SUFICIENTES PARA REDUCIR EL NIVEL DE MBF, MEDIANTE CONVERSION EN COMPUESTOS DE PUNTO DE EBULLICION MAS ELEVADO, Y POSTERIORMENTE DESTILAR EL FENOL PARA SEPARAR ESTE DE LOS COMPUESTOS DE ELEVADO PUNTO DE EBULLICION. EL FENOL SE PUEDE TRATAR DE FORMAS CONOCIDAS, COMO P.EJ. CON UNA AMINA, PARA REDUCIR EL NIVEL DE ACETOL. DICHO FENOL DE BAJO NIVEL DE ACETOL, SE PONE EN CONTACTO CON UNA RESINA ACIDA FUERTE PARA REDUCIR EL NIVEL DE MBF.
