PROCEDIMIENTO PARA PREPARAR ALCOXILADOS CON ESTRECHA DISTRIBUCION DE HOMOLOGOS UTILIZANDO COMPLEJOS DE PENTA HALOGENUROS DE ANTIMONIO COMO CATALIZADOR.

摘要

In the process described for the preparation of alkoxylates having a narrow distribution of homologs by reaction of compounds containing at least one hydroxyl group with alkylene oxide, complex compounds of antimony pentahalide with a special Lewis base are used as the catalysts. Alkoxylates having a narrow distribution of homologs and good color quality are obtained at a high conversion.
