中文摘要：

以醇溶性曙红为催化剂,在温和条件下高效催化缩醛化反应,该催化体系适应于不同种类的脂肪醛或芳香醛与短链一元醇或二元醇的羰醇缩合反应,于室温反应24 h,缩醛化产物收率58%-99%,其结构经^1H NMR,^13C NMR和HR-MS确证。

英文摘要：

The acetalization reaction of different kinds of aliphatic aldehydes or aromatic aldehydes with short chain monohydric alcohols and diols was achieved under mild conditions catalyzed by the alcohol-soluble Eosin Y.The yield of acetal compounds were 58%-99% after reaction for 24 h at room temperature.The structures were confirmed by ^1H NMR,^13C NMR and HR-MS.
