Abstract
PROCEDIMIENTO DISCONTINUO DE INTERCAMBIO IONICO PARA LA PURIFICACION DE LOS POLIOLES POLIETERES BRUTOS. UN PROCEDIMIENTO DE PURIFICACION DE LOS POLIOLES POLIETERES BRUTOS ACOMPAÑADOS POR LOS HIDROXIDOS ALCALINOS UTILIZADOS COMO CATALIZADORES EN SU FABRICACION, QUE COMPRENDE LAS SIGUIENTES STUPAS SUCESIVAS: A) MEZCLA DEL POLIOL POLIETER BRUTO CON POSO MOLECULAR 1000-10.000 CON AGUA, O DISOLUCION ACUOSA DE UN ALCOHOL ALIFATICO DE BAJO PESO MOLECULAR Y UNA RESINA DE INTERCAMBIO JONICO FUERTEMENTE ACIDA. B) CALEFACCION DE LA MEZCLA DE A) A 80 - 120°C CON BUENA AGITACION. C) SEPARACION DE LAS FASES DE B) Y TRATAMIENTO DE LAS MISMAS POR LAS TECNICAS CONVENCIONALES CON OBTENCION DEL POLIOL POLIETER PURIFICADO.
