综述了正硅酸乙酯（TEOS）的热力学性质测定方法.此外，还用原位红外光谱研究了TEOS的热分解过程。气相中的分解产物在没有氧气的情况下是有机碎片（乙醇、乙醛、乙烯、甲烷、一氧化碳），在有氧气的情况下是水、二氧化碳、乙醛和甲醛。并与热力学平衡计算和动力学模型进行了比较
A review is given on the determination of the thermodynamic properties of Si(OC 2 H 5 ) 4 (TEOS, tetraethoxysilane). In addition, the thermal decomposition of TEOS has been studied by in-situ IR spectroscopy. The decomposition products in the gas phase in the absence of oxygen are organic fragments (ethanol, ethanal, ethene, methane, carbon monoxide), and in the presence of oxygen water, carbon dioxide, ethanal and methanal. The results are compared with thermodynamic equilibrium calculations and kinetic models
