Abstract
융점 측정 장치로 자체 제작한 glass still을 이용하여 정적인 방법으로 dodecane+cyclohexanol, 1-dodecanol+N,N-dimethylformamide(DMF), p-xylene+DMF, 1-dodecanol+N-methylformamide(NMF), NMF+1-octanol, aceticacid+diethyl carbonate 및 hexadecane+diethyl carbonate 계에 대한 고약평형(SLE)을 측정하였다. 측정된 고액평형 데이터는 NRTL식에 의해 계산된 값과 비교하여 보았으며, diethyl carbonate 융점의 문헌상 오류를 확인하였다.
Solid-Liquid Equilibrium(SLE) data were measured by the static method for the systems of dodecane+cyclohexanol, 1-dodecanol+N,N-dimethylformamide(DMF), p-xylene+DMF, 1-dodecanol+N-methylformamide(NMF), NMF+1-octanol, acetic acid+diethyl carbonate and hexadecane+diethyl carbonate with the self made melting point measuring apparatus. The measured SLE data were correlated with the NRTL equation, and we found that the literature value of melting point for diethyl carbonate is not correct.
