Abstract
몇가지 알킬화피리딘(2, 3 and 4-methyl and ethylpyridine)의 해리상수의 온도 및 압력 의존성을 알아 보았으며 해리상수는 전도도법을 이용하여 측정했다. 이들 치환피리딘의 해리는 온도가 높아지면 증가하고 압력이 높으면 감소함을 알았다. 또 이들 해리상수 값에서 해리반응의 열역학적 성질을 계산하여 해리반응의 여러가지 성질을 알아 보았으며 알킬화피리딘의 특이성을 알 수 있었다.

The effects of substituents, pressure and temperature on the dissociation constants of alkylpyrines(2, 3 and 4-methyl and ethyl) were studied by measuring the dissociation constants of pyridines by conductance method at various temperatures and pressures in aqueous solution. The constants were increased as the temperature increase but decreased as pressure increase. From the constants various thermodynamic properties were calculated and discussed the dissociation reactions. It was estimated that alkylpyridines have exceptional dissociation reactions.
