Ebulliometric measurement of vapor-liquid equilibria for four binary systems: methanol + silicon tetramethoxide, methanol + silicon tetraethoxide, ethanol + silicon tetramethoxide, and ethanol + silicon tetraethoxide

The authors discuss vapor pressures of silicon tetramethoxide and silicon tetraethoxide measured with a small ebulliometer. Boiling points for the four binary systems made of alcohol (methanol and ethanol) and alkoxide (silicon tetramethoxide and silicon tetraethoxide) were further measured at 760 and 450 mmHg pressures, and their vapor-liquid equilibrium relations were determined by using the Wilson equation.
