Rheology of gels prepared with stearyl dimethyl benzyl ammonium hectorite (SDBAH) and various gelling agents in n-butyl acetate was investigated. It was found that molecular size and polarity of gelling agent molecule have influence on gelation of organic-hectorite and that the functional groups of gelling agent are related to the flow behavior of gels. From the results some gelling agents such as dimethyl sulfoxide (DMSO), nitrobenzene (NB) and methylcel1osolve (MC) showed better gelling effect than methanol which was known as one of the best gelling agents. When DMSO was added as gelling agent, the resulted gel showed the characteristic flow properties. So the structure of DMSO molecule was considered to explain these phenomena.

Stearyl dimethyl benzyl ammonium hectorite(SDBAH)에 여러 가지 gelling agent를 첨가하여 유기 용매 중에서 얻어진 gel의 rheology를 관찰한 결과 gelling agent의 분자 크기와 극성이 gelation에 영향을 미친다는 사실과 관능기에 따라 gel의 유동 성질이 변화된다는 것을 알 수 있었다. 우수한 gelling agent로 알려진 methanol이나 propylene carbonate (PC) 뿐만 아니라 methylcellosolve(MC), dimethyl sulfoxide(DMSO) 및 nitrobenzene(NB)등도 매우 우수한 gel 효과를 얻을 수 있었으며, 특히 DMSO 첨가시에는 독특한 유동 성질을 나타내고 있는데 그것의 분자 구조적인 면이 고려되었다.
