    摘要: A process for preparing an alkoxylation catalyst suitable for alkoxylating compounds such as active hydrogen-containing compounds wherein an alkoxylated alcohol mixture, a calcium-containing compound that is at least partially dispersible in the alkoxylated alcohol mixture, and a carboxylic acid are mixed together to produce a calcium-containing composition having titratable alkalinity, the composition being obtained under conditions to prevent loss of water, the composition being at least partially neutralized with an inorganic acid under conditions to prevent loss of water to produce a partially neutralized calcium-containing catalyst.
