Abstract

Un proceso continuo para la preparación de polioxialquilén poliéteres que utiliza catalizador CMD como catalizador de polioxialquilación, emplea laadición continua de óxido de alquileno en conjunto con la adición continua de iniciador ycatalizad or a un reactor de oxialquilación continuo.Específicamente se refiere a un proceso continuo para la preparación de un producto polioxialquilén poliéter en el cual una primer porción de una mezclacatalizador CMD/iniciador inicialefectiva para co menzar la polioxialquilación de dicho iniciador inicial luego de la introducción de óxido de alquileno endicho reactor continuo; es puesto en un reactor continuo, donde dicho proceso comprende: a) introducir continuamente en elreactor uno o más ó xidos dealquileno; a) introducir continuamente a la entrada del reactor mezcla de catalizador CMD adicional/iniciador adicional de forma tal que se mantenga laactividad catalítica; a) introducir continuamente en el reactoren adición al iniciado r en la entrada del reactor uno o más iniciadores continuamente loscuales pueden ser los mismos o distintos de dicho iniciador; b) polioxialquilar los iniciadores combinados realizando continuamente por lo menos los pasosa);a) y a) de arriba hasta q ue se obtiene un producto polioxialquilén poliéter de peso molecular promedio en base a número deseado; y c) removercontinuamente dicho producto polioxialquilén poliéter de dicho reactor continuo. Lospolioxialquilén poliéteres son artículo s comerciales bienconocidos con numerosas aplicaciones. Por ejemplo, los copolímeros de polioxialquileno en bloque, al azar, y en bloque al azar, son usadosampliamente como tensioactivos no iónicos.Sin embargo el mayor usao de los poli oxialquilén poliéteres es la preparación de polímeros.
