摘要
用气相色谱法实验测定了水＿异丙醚＿苯酚的三元系在46℃的等温截面相图。相图上呈现两个两相共存区域和一个单相区域。在46℃水和异丙醚存在两相,当逐渐溶入苯酚后,水富端很小,而醚相中异丙醚摩尔分数逐渐减小到25.4%,苯酚逐渐增加到29.0%,这表明在醚相中苯酚可达到较大溶解度。在46℃水和苯酚也存在两相,在三元系中异丙醚在水相和苯酚相中的溶解度都不大。该相图为工业上萃取提供了一定的基础工作。
The isothermal section at 46℃ in water_isopropyl ether_phenol ternary system has been measured experimentally with gas chromatograph method.There are one single_phase region and two two_phase regions in the phase section.At 46℃,there exists two phases in water and isopropyl ether system. With phenol's increasing in solution,the mole fraction of isopropyl ether decreases to 25.4% gradually and the mole fraction of phenol increases to 29.0% gradually in ether phase.It is shown that phenol can get to larger solubility in ether phase and it is very useful for industrial extraction.
