An object of the present invention is to provide a method capable of producing a tetraalkoxysilane with a high energy efficiency and with a high yield. The present invention provides a method for producing a tetraalkoxysilane, the method including: a first step of reacting an alcohol with a silicon oxide; and a second step of bringing a vaporized component of the reaction mixture obtained in the first step into contact with a molecular sieve.

Method for producing tetraalkoxysilane

An object of the present invention is to provide a method for producing tetraalkoxysilane while saving energy at a high yield. Tetraalkoxysilane can be produced while saving energy at a high yield by the method including a first step of reacting alcohol with carbon dioxide in the presence of a dehydrating agent and/or in a reactor provided with a dehydrating means, and a second step of reacting a reaction mixture obtained in the first step with silicon oxide.
