结果实验数据绘制在图 6 中，其中将各个点呈现为三个等温线中每一个的压力（磅/平方英寸）与摩尔百分比二氧化碳的关系图：32°F、—4°F 和—40°F。三个等温线的蒸气线中存在明显的反向曲率。这种现象随着温度降低而加剧。 Poettman 和Katz (8) 注意到在较高温度下也存在类似的情况。图 7 和图 8 表示数据的交叉图，其中温度相对于沿着液相和气相等压线的成分绘制。这两个图已通过 Poettman 和 Katz 的数据 (8) 以及二氧化碳和丙烷的蒸气压数据 (7) 进行了扩展。所有数据都非常吻合。二氧化碳和丙烷的平衡比 (y/x) 绘制在图 9 中。在二氧化碳蒸气压下，二氧化碳的比例已外推至 K= 1。没有尝试推断我目前地址（德克萨斯州贝敦 Humble Oil and Refining Co.）的理论。
RESULTSThe experimental data are plotted on Figure 6, which presents the individual points as a plot of pressure in pounds per square inch versus mole per cent carbon dioxide for each of the three isotherms: 32,—4, and—40 F. There is a reverse curvature apparentin the vapor lines of the three isotherms. This phenomenon increases as the tempera-ture decreases. Poettman andKatz (8) noted a similar condition at the higher temperatures. Figures 7 and 8 represent a cross plot of the data in which temperature is plotted against compositionalong isobars for the liquid and vapor phases. The two plots have been extended by the data of Poettman and Katz (8) and the vapor pressure data of carbon dioxide and propane (7). All the data are in good agreement. The equilibrium ratios (y/x) for carbon dioxide and propane are plotted in Figure 9. The ratios for carbon dioxide have been extrapolated to K= 1 at the vapor pressure of carbon dioxide. No attempt was made to extrapolate theratios for i Present address, Humble Oil and Refining Co., Baytown, Tex.
