TS-1 zeolite was synthesized by hydrothermal method using both tetraethylorthosilicate (TEOS) and silicon gel as the silicon source.
同时以正硅酸乙酯(TEOS)和硅胶为硅源，采用水热合成法制备了TS - 1分子筛。

The composite silica microsphere was obtained through the polymerization of urea and formaldehyde occurred in the silica sol that prepared from the hydrolyzation of tetraethylorthosilicate.
Then the new cage-like vinyl silsesquioxanes(VS) were synthesized by the reaction of vinyl-tetra-coordinate silicon with tetraethylorthosilicate in the condition of tetramethyl ammonium hydroxide.
