Abstract
Decylpyridinium Chloride 수용액의 c.m.c를 10℃부터 50℃사이의 온도에서 전기전도도법으로 결정하였던바 온도에 따른 c.m.c. 변화는 15℃근처에서 최소값을 보였다. Clausius-Clapeyron형의 식과 log(c.m.c)의 온도방법식으로 부터 micelle화 과정에 따른 ΔHm, ΔFm˚, ΔSm, ΔSm˚ 및 ΔCpm을 얻어 dodecylpyridinium chloride와 dodecylpyridinium bromide의 값들과 비교 검토하였다.

The critical micelle concentrations of decylpyridinium chloride in aqueous solutions have been determined by the electrical conductance measurements in the range of 10°-50℃. The temperature variation of the critical micelle concentrations has shown the minimum at the vicinity of 15℃. The Clausius-Clapeyron type equation of log (c.m.c.) versus temperature has been established. The values ΔHm and the other thermodynamic properties associated with micelle formation have been determined using the above equation and compared with that of dodecylpyridinium chloride and dodecylpyridinium bromide.
