摘　　要：利用四丁基硫酸氢铵(TBAHS)和大孔树脂(D201型)支载的硫酸氢季铵盐(D201-HSO4),分别催化环氧化合物或氮杂环丙烷与甲醇的开环反应,以高产率得到β-甲氧基醇或β-甲氧基胺.两种催化剂对该反应都很有效,但大孔树脂支载的硫酸氢季铵盐(D201-HSO4)易于制备,并可以重复使用.Tetrabutylammonium bisulfate （TBAHS） and macroporous resin （D201）-supported quatemary ammonium bisulfate （D201-HSO4） were used as catalysts in ring-opening reactions of epoxides and aziridines with alcohols respectively, and high yields of corresponding β-alkoxy alcohols or β-alkoxy amines were obtained. These two catalysts were both efficient in the reactions, but the resin-supported quaternary ammonium bisulfate （D201- HSO4） was more convenient for preparation and recycling.
