Kinetic peculiarities of the early stages of the processes of acid-catalyzed hydrolysis and condensation in sol-gel systems tetraethoxysilane (TEOS)–ethanol–water have been investigated by gas chromatography. Kinetic parameters of the process, evaluated using quantum-chemical calculations, satisfactorilly coincide with the ones determined experimentally.
