A process for obtaining a mixture of C4-C8 and C9-C18 alkyl monoether of saccharide, comprising: a) a first step of acetalization or trans-acetalization of a saccharide or of a mixture of saccharides with a C4-C8 aliphatic aldehyde or the acetal thereof, b) a second consecutive or simultaneous step of acetalization or trans-acetalization of the product obtained in a) of the saccharide or mixture of saccharides with a C9-C18 aliphatic aldehyde or the acetal thereof, c) a step of catalytic hydrogenolysis of the saccharide acetals obtained, and d) a step of recovery of a mixture of C4-C8 and C9-C18 alkyl saccharide monoethers. The invention further relates to a mixture of C4-C8 and C9-C18 alkyl saccharide monoethers and the use thereof as a surfactant.

Long-chainalkylglucosidesurfactants have been obtained with good conversions and selectivities by the transacetalation of butylglucosides with different fatty alcohols as well as by one-stepdirect glycosidation, using H-Beta zeolites as catalyst. The influence of the different process variables such as temperature, molar ratio of reactants, and fatty alcohol chain length has been investigated
