Abstract
9가지의 2성분계(n-hexane∼n-butanol계, acetone∼methanol계, acetone∼n-propanol계, methanol∼n-propanol계, n-hexane∼n-propanol계, acetone∼n-hexane계, methanol∼n-butanol계, methanol∼n-hexane계, acetone-n-butanol계)에 대하여 760 ㎜Hg에서 비점을 실측했다. 여기서 얻은 비점데이터를 기초로 하여 각계에 대한 성분 1과 성분 2의 무한희석활성도계수를 구했다. 또한 Wilson식을 기초로 하여 무한희석활동도계수로 부터 Wilson parameter와 기액평형치를 구하였으며 계산치와 문헌치 및 실험치와 비교하였다.
Boiling points of 9 binary systems(n-hexane-n-butanol, acetone-methanol, acetone-n-propanol, methanol-n-propanol, n-hexane-n-propanol, acetone-n-hexane, methanol-n-butanol, methanol-n-hexane, acetone-n-butanol) were measured at the 760 ㎜Hg. Using the Gautreaux & Coates equation, infinite activity coefficients of each system were calculated from the boiling poins curves of the 9 systems. Furthermore from the infinite activity coefficients Wilson parameters and isobaric vapor-liquid equilibria data were obtained. These data were compared with the experimental and reported data.
