The hydrolysis of tetraethyl orthosilicate in the preparation of monodisperse silica particles was studied by means of extract-freeze separate-GC analysis. The effect of the parameters on the hydrolysis rate was investigated in the temperature range: 25-45℃; ammonina concentration: 0.5-0.2mol•L-1; water concentration: 6.0-15.0mol•L-1.A kinetics eqution of hydrolysis was obtained by the which could be used under experimental conditions most in use in the preparation of monodisperse particles in ethanol with ammonina as catalyst.
