ALKOXYLATING METHOD USING CALCIUM BASE CATALYST

摘要

A process for preparing an alkoxylation catalyst in which the catalyst pre-mix is formed by admixing an alkoxylated alcohol with a calcium containing compound which is dispersible in the alkoxylated alcohol, an inorganic acid and an aluminum trialkoxide, the pre-mix being heated to a temperature and for a time sufficient to effect at least partial exchange reaction between the alkoxide groups of the aluminum alkoxide and the hydroxyl groups of the alkoxylated alcohol. There is also disclosed and claimed an alkoxylation process utilizing the catalysts formed as described above.
