尺寸排阻色谱(SEC)分别与傅立叶变换红外光谱(FT-IR)联用，被证明是唯一适用于研究有机官能团三烷氧基硅烷的水解和缩合反应。尺寸排除层析提供了一种分离方法，它揭示了关于三烷氧基硅烷反应的以前未被证实的信息。将色层与具有漫反射光学的FT-IR分光光度计接口，可以识别单独的反应产物，包括Slanetrlol和环四聚体。研究了苯基三乙氧基硅烷在四氢呋喃水溶液中的反应动力学。反应硅烷在不同介质(如水和水-有机)中的行为也可以被监测，并被证明是本质上不同的。
Size-exclusion chromatography (SEC), severally and In com-bination with Fourier transform Infrared (FT-IR) spectroscopy, Is shown to be uniquely applicable to the Investigation of the hydrolysis and condensation reactions of organofunctional trialkoxysilanes. Size-exclusion chromatography provides a method of separation which reveals previously undemons-trated Information about the reactions of trialkoxysilanes. Interfacing the chromatography to a FT-IR spectrophotometer with diffuse reflectance optics allows Identification ofIn-dividual reaction products Including the sllanetrlol and the cyclic tetramer. Reaction kinetics are followed for phenyltrlethoxysllane In aqueous tetrahydrofuran. The behavior of the reacting silanes In different media (eg, aqueousand aqueous-organic) can also be monitored and Is demonstrated to be substantially different.
