Abstract

Patente de Invenção <B>"POLIOXIALQUILAçãO DIRETA DE GLICERINA COM CATALISADORES DE CIANETO DE METAL DUPLO"<D> Acidificação, neutralização ou remoção de impurezas básicas a partir de iniciador de baixo peso molecular sensível a ácido ou acidificação de um calcanhar do reator, antes da adição do dito iniciador de baixo peso molecular sensível a ácido, permite a oxialquilação direta de iniciador de baixo peso molecular sensível a ácido adicionado de maneira contínua, para produzir polióis, iniciados ou co-iniciados com iniciador de baixo peso molecular sensível a ácido, de polioxialquileno, na presença de um catalisador de cianeto de metal duplo. O iniciador de baixo peso molecular sensível a ácido preferido é glicerina.
