Beschreibung
Zusammenfassung:A process of preparing an alkoxylation catalyst wherein a catalyst precursor which is formed from an alkoxylated alcohol, calcium hydroxide, carboxylic acid, inorganic acid, and propylene oxide, is mixed with an antioxidant, preferably butylated hydroxyl toluene. A process of alkoxylation using the catalyst of the present invention. Cette invention concerne un procédé de préparation d'un catalyseur d'alcoxylation consistant à mélanger un précurseur de catalyseur qui est formé à partir d'un alcool alcoxylé, d'un hydroxyde de calcium, d'un acide carboxylique, d'un acide inorganique, et d'un oxyde de propylène avec un antioxydant, de préférence un hydroxytoluène butylé. Un procédé d'alcoxylation utilisant le catalyseur selon l'invention est en outre décrit.
