An efficient and facile procedure for synthesis of octyl polyglucoside
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%.
