Methyl glucoside is synthesized by methanol and glucose with one step method. Sulfonic acid type mesoporous material is used as catalyst, which is characterized by field emission scanning electron microscopy （SEM） , high resolution transmission electron microscopy （TEM）,low temperature N2-adsoqtion-desorption isotherms （BET） , thermogravimetric analysis （TG）. The optimal reaction parameters for the synthesis of methyl glucoside are shown as follows ：0. 6 g of the catalyst ,28 of the molar ratio of methanol and glucose, 115℃ of reaction temperature and 2 hours of reaction time. The yield of methyl glucoside can reach 95.67%. The chemical structure of methyl glucoside is characterized by Fourier transform infrared spectrophotometry （ FT-IR）.
