Abstract

UN PROCESO PARA ELABORAR POLIOLES POLIETERES CONVENCIONALES Y DE BAJA INSATURACION EN EL QUE, DURANTE LA POLIMERIZACION, UNA PARTE DE LA FASE LIQUIDA O DE VAPOR ES CONTINUA O PERIODICAMENTE RETIRADA DEL REACTOR DE POLIMERIZACION Y TRATADA PARA EXTRAER ALCOHOL ALILICO Y PROPOXILATOS DE ALCOHOL ALILICO INFERIOR. EL OXIDO DE PROPILENO O BIEN OXIDO DE PROPILENO Y POLIOL POLIETER DE LA PARTE EXTRAIDA RETORNA AL REACTOR. EL PROCESO PUEDE SER LLEVADO A CABO A ALTAS TEMPERATURAS Y/O BAJAS CONCENTRACIONES DE CATALIZADOR. PUEDEN PREPARARSE POLIOLES POLIETER CON CONTENIDOS DE MONOALCOHOL EXCEPCIONALMENTE BAJOS.
