Abstract

Un procedimiento para la polioxialquilación directa de un iniciador sensible a los ácidos que tiene un peso molecular por debajo de 400 Da en la presencia de un complejo catalizador de cianuro de metal doble, dicho procedimiento comprende: a) establecer las condiciones de oxialquilación en un reactor de oxialquilación en la presencia de un catalizador de cianuro de metal doble; b) introducir continuamente en dicho reactor óxido de alquileno e iniciador sensible a los ácidos que tiene un peso molecular por debajo de 400 Da; y c) recuperar un producto poliéter iniciador oxialquilado; en el que la desactivación del catalizador de cianuro de metal doble es reducida por una o más entre las etapas de: i) acidificar dicho iniciador sensible a los ácidos que tiene un peso molecular por debajo de 400 Da antes de introducir dicho iniciador sensible a los ácidos en dicho reactor; ii) tratar dicho iniciador sensible a los ácidos con una cantidad efectiva de una sustancia reactiva con las bases o adsorbedora de bases distinta de un ácido antes de introducir dicho iniciador sensible a los ácidos en dicho reactor.
