摘要：

The catalysis of the glycosylation reaction (Fischer) by acidic clays, and in particular the montmorillonite KSF/O, was studied in the case of the glucosylation of butanol and dodecanol. The catalysis was shown to be mostly homogeneous, involving an acidity transfer from the solid to the alcoholic phase. Ultrasound promoted an intensification of this phenomenon leading to an increase of the conversion rate of glucose, which, in the case of dodecanol, gave rise to high yields of oligomeric species (mostly 1,6-polyglucose).
