Abstract

SE MUESTRAN UN CATALIZADOR Y PROCESO PARA PREPARARLO Y SU USO EN LA POLIMERIZACION DE TETRAHIDROFURANO PARA PRODUCIR ETER POLITETRAMETILENO DE ETERGLICOL. EL CATALIZADOR ES UNA MEZCLA DE UNA RESINA FLUORADA QUE CONTIENE GRUPOS DE ACIDO SULFONICO Y UN UNA RESINA FLUORADA QUE CONTIENE GRUPOS DE ACIDO CARBOXILICO. EL CATALIZADOR ESTA PARCIALMENTE DESHIDRATADO PARA CONTENER DE 1,000 A 2,000 PPM DE AGUA, DE MANERA QUE CUANDO ES USADO PARA POLIMERIZAR TETRAHIDROFURANO, EL PRODUCTO POLITETRAMETILENO DE ETERGLICOL DARA UN PESO MOLECULAR MEDIO DE 250 A 4,000.
