Fischer glycosidation ofd-glucose andn-butanol has been carried out successfully using different acid zeolites as catalysts. Both butylglucofuranoside and pyranoside are obtained during reaction. It has been found that large pore tridirectional zeolites with high Si/Al ratios such as faujasite and beta are the most suitable catalysts. The influence of the molar ratio alcohol/d-glucose on the selectivity to alkylmonosaccharide has been also studied.
