초록

서독 Hoechst사의 acrylonitrile 제조시 부산되는 oxazole-acetonitrile-water계의 분리공정 설계를 위하여, 이들 삼성분계의 새로운 기액평형데이터를 recirculating still에 의해 1013mbar에서 측정하였으며, 이로부터 각 성분의 활동도 계수를 구하였다. 각 성분의 활동도 계수는 Wilson 및 NRTL의 식으로서 합치시켜 각각의 상수를 계산하였으며, 측정한 삼성분계 데이터는 systematic error를 포함했는지의 여부를 보기 위하여, 다성분계를 위한 two point consistency test에 따라 수행한 열역학적 일치성시험을 만족함을 확인하였다.

New vapor-liquid equilibrium data for the ternary mixture oxazole-acetonitrile-water, which are by-products of acrylonitrile manufacturing process in Hoechst Co., were determined by using recirculating still at 1013 mbar. These experimental data were satisfactorily correlated by Wilson and NRTL equation for the activity coefficient and were found to be thermodynamically consistent by two point consistency test for a multicomponent.
