Abstract
Organically modified silica gels were prepared from a mixed solution of Si (OEt) 4 (TEOS) and RMeSi (OMe) 2 (DSA : R=CH3 (Me), CH=CH2 (Vinyl), C6H5 (Ph)) by sol-gel process. The pore structure of the modified silica gels was investigated by N2 adsorption. The organically modified silica gels were formed at amount fraction of DSA (XD=DSA/ (TEOS+DSA)) of 0.3 or smaller. The amount of R groups introduced in the silica gels was increased with increasing XD. Me- and Vinyl-modified silica gels possessed higher micropore volume and pore diameter than that prepared from TEOS only. The adsorption isotherm of N2 on Ph-modified silica gels was altered from type I to type II with increasing XD, accompanying a decrease of specific surface area and micropore volume. These facts revealed that the pore structure of silica gel was changed by the introduction of R groups to DSA for the silica gels.
