Article Preview

The functionalized porous hybrid silica as a separation medium was synthesized by using Cetyltrimethyl Ammonium Bromide(CTAB) as template, (3-aminopropyl) triethoxysilane (APTES) and tetraethyl orthosilicate (TEOS) as reactive monomer, with the existence of ammonia, reacting for 80 h at 80°C. The influences of the main reactants ratio and the pH of reaction on the structure of the materials were investigated through the characterization by Fourier-Transform infrared spectrometer (FTIR), scanning electron microscope (SEM) and pore structure measurements. And the best reaction conditions were optimized. The monolithic column made by this porous hybrid silica has been applied to separate benzylideneacetone and o-chlorotoluene, which are the main composition in electroplating additive.
