Strontium-containing alkoxylation systems are used as catalysts for the alkoxylation of alcohols of all classes. The reaction is carried out at temperatures of from about 90 to about 260°C to yield an alkoxylation product. The products obtained have very narrow adduct distribution with low levels of by-products and unreacted free alcohols. Several classes of materials which promote these reactions are disclosed.

锶烷氧基化体系可用作各类醇的烷氧基化催化剂。反应在约 90 至约 260°C 的温度下进行,生成烷氧基化产物。得到的产物具有非常狭窄的加成分布,副产物和未反应的游离醇含量很低。已公开了几类可促进这些反应的材料。
