主　　题：Alkyl polyglucoside Sulfate acid-silica gel Solid acidic Catalyst 

摘      要：Nonionic surfactant alkyl polyglucoside （APG） was prepared by direct glycosidation of alkyl alcohol with glucose in the presence of sulfate acid-silica gel （H2SO4/SiO2） as solid acidic catalyst. The quantity of catalyst was only of 1 wt%, based on the glucose, and the conversion of glucose was close to 100% at 110 ℃ in 1.5 h. The product was characterized by FT-IR, mass and ^1H NMR spectra. The degree of polymerization （DP） of the glucose in the product was 1.37, and critical micelle concentration （CMC） of product was only 0.0104 wt%.
