摘要：

The mechanisms of group =SiOR (R = CH3, CHO, COCH3) thermal decomposition reactions on Aerosil surfaces were investigated by IR spectroscopy, mass spectrometry, quantum chemical MNDO and AM1 methods, and RRKM theory. The activation energies and rate constant prefactors were calculated by theoretical methods and compared with experimental data.
