Provided is a method for efficiently producing alkoxysilanes that are useful as various functional chemicals. In order to produce alkoxysilanes efficiently, an ethoxy- or methoxysilane and an alcohol are caused to react using, as a catalyst, for instance an inorganic solid acid having a regular-pore and/or layered structure. Zeolites, montmorillonites or the like can be used as the inorganic solid acid. When a zeolite is used as the catalyst, the silica/alumina ratio of the zeolite ranges preferably from 5 to 1000. The reaction can be promoted through irradiation of microwaves.

transesterification depended on the ratio of numbers of alkyl groups in tetraalkoxysilane and alcohol used. The time required for equilibrium in the distribution of alkoxysilane species in the solution was different with the variety of butylalcohols used, suggesting the presence of steric effect of butylalcohols on this reaction.
