Abstract
POLIALCOHOLES DE POLIETER TENIENDO UN PESO EQUIVALENTE DE DESDE 200 A 4000 SE PREPARAN POR UN PROCESO DE ESTA INVENCION. EL PROCESO USA BARIO O ESTRONCIO CONTENIENDO CATALIZADORES DE ALCOXILACION PARA PROVEER PRODUCTOS CON NO SATURACION REDUCIDA EN COMPARACION CON SIMILARES PRODUCTOS OBTENIDOS CON CATALISIS DE HIDROXIDO POTASICO. EN UNA INCORPORACION PREFERENTE DEL PROCESO, SE AÑADE AGUA DURANTE LA REACCION DEL COMPUESTO MONOEPOXIDO CON EL INICIADOR. LA CANTIDAD DE AGUA AÑADIDA DURANTE LA REACCION DEL COMPUESTO MONOEPOXIDO CON EL INICIADOR. LA CANTIDAD DE AGUA AÑADIDA ES UNO POR CIENTO O MENOS DE PESO DEL PESO TOTAL DE COMPUESTO MONOEPOXIDO PARA SER REACCIONADO CON EL INICIADOR.
