Tetrakis orthosilicate

General Considerations. The following chemicals were commercially available and used as received 3,3,3-Triphenylpropionic acid (Acros), 1.0 M LiAlH4 in tetrahydrofuran (THF) (Aldrich), pyridinium dichromate (Acros), 2,6 di-tert-butylpyridine (Acros), dichlorodimethylsilane (Acros), tetraethyl orthosilicate (Aldrich), 3-aminopropyltrimethoxy silane (Aldrich), hexamethyldisilazane (Aldrich), tetrakis (diethylamino) titanium (Aldrich), trimethyl silyl chloride (Aldrich), terephthaloyl chloride (Acros), anhydrous toluene (Acros), and n-butyllithium in hexanes (Aldrich). Anhydrous ether, anhydrous THF, anhydrous dichloromethane, and anhydrous hexanes were obtained from a packed bed solvent purification system utilizing columns of copper oxide catalyst and alumina (ether, hexanes) or dual alumina columns (tetrahydrofuran, dichloromethane) (9). Tetramethylcyclopentadiene (Aldrich) was distilled over sodium metal prior to use. p-Aminophenyltrimethoxysilane (Gelest) was purified by recrystallization from methanol. Anhydrous methanol (Acros) was... [Pg.268]

Other than cellulose, several polysaccharides such as alginate [201-203], chi-tin [204-206], chitosan [207], or pectin [208] have witnessed a dramatic evolution in the formation of silica-based composite materials with increasing textural control. A more systematic approach, designed to understand the composite s textural variability induced by the different polysaccharides, has been proposed by Shchipunov and Karpenko [209]. These authors have silicified a wide variety of polysaccharides using the same silica source, tetrakis(2-hydroxyethyl) orthosilicate (THEOS), whose water solubility allowed an expedite interaction with the selected biopolymer rendering diverse textures that can be directly attributed to different polysaccharides. [Pg.635]
