摘要
组成分析是汽液平衡测定过程中常常遇到的较为困难的问题,多少年来,人们一直在寻求可靠的实验方法,以使能在较低代价下对汽液平衡数据进行准确测定.沸点计法的较大进展就足以说明这一点.为了提高测定的精度和准确度,拟静态操作在沸点计法测定汽液平衡中得到了应用.为此,研究适合拟静态法的新型沸点计对汽液平衡的测定具有重要的意义.
Based on the error equation of ebulliometry:
the t-xo line measured by a ebulliometer has the best approximation of the bubble-point line t-x when the circulation is set on the pseudo-static state where the condensate reflux diminishes to zero (r = 0). In this paper, the principle and realization of the method are further studied from different points of view, and three newly designed ebulliometers with pump stirrer are shown. The functions of the new ebulliometers and the reliability of the method are tested through experiments done in different concentration ranges and in different ways.
