Abstract
La presente invencion se refiere a procesos para preparar polioles acabados en oxido de etileno (EO) en los que no es necesaria la retirada de los residuos cataliticos o sales formadas por la neutralizacion del catalizador basico antes de descargar el poliol del reactor porque la neutralizacion ocurre durante o despues de la carga de material de partida de un lote posterior. Los procesos de la invencion permiten la preparacion de intermedios catalizados con DMC y sus extremos de EO catalizados en condiciones basicas en el mismo reactor. Los polioles producidos mediante los procesos de la invencion tienen un alto contenido de grupos hidroxilo primarios y pueden ser utiles para producir espumas de poliuretano, elastomeros, obturadores, recubrimientos, adhesivos y similares.
