CA 2678734

A process for preparing an alkoxylation catalyst wherein a catalyst precursor which is formed from an alkoxylated alcohol and an alkaline earth metal compound to form a dispersion of an alkaline earth metal species is reacted with at least one alkylene oxide to alkoxylate at least a portion of the alkoxylated alcohol and forms a block alkoxylated alcohol.

L'invention concerne un procédé pour préparer un catalyseur d'alcoxylation. Dans ledit procédé, un précurseur de catalyseur formé d'un alcool alcoxylé et d'un composé de métal alcalino-terreux pour former une dispersion d'une espèce de métal alcalino-terreux est mis à réagir avec au moins un oxyde d'alkylène afin d'alcoxyler au moins une partie de l'alcool alcoxylé et produire un alcool alcoxylé séquencé.
