An alkyl xyloside synthesis process is as follow: silica gel and anhydrous ethyl ether are slowly added under stirring into a secondary alkyl sulfonic acid, the ethyl ether is removed by concentrating, a solid acid catalyst is obtained after drying, xylose and a long-chain alkyl alcohol are added into a reactor in a molar ratio of 1:2-10, after the catalyst is added, the temperature is raised to 90-110 DEG C for reaction for 2-6 hours under 5-50mmHg pressure, after the completion of the reaction, the catalyst is filtered off, and after the excess alkyl alcohol is removed by vacuum distillation, alkyl xyloside is obtained, wherein the catalyst is added in an amount of 2% to 5% of the total mass of the xylose and the alkyl alcohol. The alkyl xyloside synthesis process has the advantages of high xylose conversion rate and selectivity, and easy industrialized production.
