Abstract

Proceso para la preparacion de polioles que tienen 3 o 4 grupos hidroxilo, a partir de un aldehído y formaldehído en presencia de agua, seguido por la hidrogenacion del producto de aldolizacion en la presencia de un catalizador de hidrogenacion a una temperatura elevada. El aldehído es obtenido mediante una reaccion de aldolizacion de un aldehído que tiene al menos dos átomos de alfa-hidrogeno y una formula de acuerdo con R1CH2CHO, en donde R1 es seleccionado de un grupo que comprende hidrogeno, grupos alquilo C1-7 que pueden tener sustituyentes cicloalquilo, grupos cicloalquilo, grupos arilo y grupos aralquilo C1-7, con formaldehído en la presencia de agua en una cantidad de 20-70% en peso, preferiblemente 40-60% en peso y en la presencia de una resina de intercambio de aniones. La hidrogenacion es llevada a cabo preferiblemente en el presencia de agua. Otro objeto de la solicitud es el producto obtenido por el proceso descripto.
