Abstract
Los catalizadores de cianuros de multiples metales son catalizadores efectivos para la polimerizacion que abre el anillo de epoxidos a polieteroles. Loscatalizadores de cianuros de multiples metales en la polimerizacion de epoxidos pueden serutiliza dos en concentraciones de catalizador menores de 100 ppm. Unadisminucion de la actividad del catalizador durante la polimerizacion puede llevar durante una detencion completa de la reaccion a condiciones peligrosas enlas instalaciones deproduccion. Estos problemas son prohibitivos para el uso técnico de catalizadores de cianuros de multiples metales en estas pequenasconcentraciones. Por otro lado, por razones de costos, un procedimiento de polimerizacion con concentracionesclaramente superior es a 100 ppm de catalizadoresde cianuros de multiples metales es economicamente poco atractivo. En la produccion técnica de poliesteroles por medio de catálisis de cianuros de multiplesmetales, son indeseables las variaciones enel procedimiento de p roduccion, de modo que es necesario hallar medidas que permitan evitar estas variaciones.Procedimiento para la preparacion de alcoholes de poliéter por conversion catalítica de compuestos H-funcionales con oxidos de alquileno,en donde se utilizacomo catalizador por lo menos un compuesto de cianuro de multiples metales, el contenido de heteroátomos elegidos entre el grupo que comprende nitrogeno,fosforo, arsénico, antimonio, azufre, selenio, teluro, fluor, cloro, bromo yyodo, en las impurezas básicas y ácidas presentes en la sustancia iniciadora y/oen los oxidos de alquileno, que disminuyen la actividad del catalizador, es siempre menor de 100 ppm. Preferentemente, los compuestos H-funcionales y/o losoxidos dealquileno son sometidos a u n tratamiento con absorbentes heterogéneos, antes de la conversion, para el empobrecimiento de las impurezas básicas yácidas y como adsorbentes heterogéneos se usan solidos con centros básicos o ácidos, como serintercambiadores de iones orgánicos si licatos en capas,alumosilicatos, zeolitas y/u ortos oxidos mixtos con centros básicos o ácidos. La sustancia iniciadora y los oxidos de alquileno pueden ser mezclados con
