七苯基倍半硅氧烷三硅醇的制备及表征

Preparation and Characterization of Heptamertic Phenyl Silsesquioxane Trisilanol

以苯基三氯硅烷为单体、苄基三甲基氢氧化铵为催化剂,通过水解、缩合制备出八苯基倍半硅氧烷(OPS)。在此基础上,进一步合成了七苯基倍半硅氧烷三硅醇。采用傅立叶变换红外光谱(FT-IR)、核磁共振谱(NMR)以及X射线衍射(XRD)等检测手段对产物的结构进行了表征。结果表明,成功合成了七苯基倍半硅氧烷三硅醇。

Octaphenylsilsesquioxane（OPS）was prepared by hydrolytic condensation from phenyltrichlorosilane catalyzed by benzyltrimethylammonium hydroxide.Further,heptamertic phenyl silsesquioxanetrisilanol was synthetized on the base of OPS.The structures of these products were characterized by FourierTransform Infrared Spectrography（FT-IR）,Nuclear Magnetic Resonance Spectrography（NMR）and X-ray diffraction（XRD）.The results showed that heptamertic phenyl silsesquioxanetrisilanol was synthetized successfully.
