졸-겔법에 의해 합성한 실리카 졸의 GC 및 GC/MASS 분석 = GC and GC/MASS Analysis of Silica Sol Synthesized by the Sol-Gel Method

다국어 초록 (Multilingual Abstract)

The optimal condition for reaction of silica sol at room temperature(25±1℃) was identified when the mole ratio of TEOS : EtOH : H₂0 : HCl was 0.345 : 0.390 : 0.612 : 1.21 x 10^(-3). The equilibrium state reached when the hydrolysis for TEOS was proceeded for 40~50 minutes at the room temperature, and the volume percent of ethanol which was detected from GC column reached to 61.6%. In order to identify the path for the molecular growth of intermediate, hydroxyl group of intermediate was change into TMS by the. TMCS, so that monomer and tetrasilicate were 92% based on the amount of TEOS by the GC/MASS.
