Oxyalkylated products having a narrow molecular weight range, which are particularly suitable for use as surfactants, can be obtained by the reaction of C₂₋₄ alkylene oxides with linear or branched monohydric alcohols or (alkyl)phenols having 6 to 30 carbon atoms in the presence of specific catalysts. These catalysts are magnesium aryloxides or the reaction products of magnesium aryloxides or high molecular weight magnesium alkoxides with phosphorus-containing acids or esters.
在特定催化剂存在下,C₂₋₄亚烷氧基与具有 6 至 30 个碳原子的直链或支链一元醇或(烷基)酚发生反应,可获得分子量范围较窄的氧烷基化产品,特别适合用作表面活性剂。这些催化剂是芳基氧化镁或芳基氧化镁或高分子量烷氧基镁与含磷酸或酯的反应产物。
