测量了二元混合物氮气+丙酮和氧气+丙酮的气液平衡数据，并将其与文献中的可用实验数据进行比较。饱和液体线是通过合成方法在高压观察池中在指定温度和液相组成下确定的。对于氮气 + 丙酮，测量了 223 K 至 400 K 之间直至 12 MPa 压力的八个等温线。对于氧气 + 丙酮，测量了 253 K 和 283 K 直至 0.75 MPa 压力的两个等温线。由此，饱和液相中气体成分的最大含量分别为0.06mol/mol(氮)和0.006mol/mol(氧)。根据这些数据，计算亨利定律常数。此外，还用分析方法研究了氮气+丙酮在指定温度和压力下的饱和蒸汽线。测量了 303 K 和 343 K 之间直至 1.8 MPa 压力的三个等温线。所有现有数据均与现有数据进行比较...
Vapor–liquid equilibrium data of the binary mixtures nitrogen + acetone and oxygen + acetone are measured and compared to available experimental data from the literature. The saturated liquid line is determined for both systems at specified temperature and liquid phase composition in a high-pressure view cell with a synthetic method. For nitrogen + acetone, eight isotherms between 223 K and 400 K up to a pressure of 12 MPa are measured. For oxygen + acetone, two isotherms at 253 K and 283 K up to a pressure of 0.75 MPa are measured. Thereby, the maximum content of the gaseous component in the saturated liquid phase is 0.06 mol/mol (nitrogen) and 0.006 mol/mol (oxygen), respectively. On the basis of these data, the Henry’s law constant is calculated. In addition, the saturated vapor line of nitrogen + acetone is studied at specified temperature and pressure with an analytical method. Three isotherms between 303 K and 343 K up to a pressure of 1.8 MPa are measured. All present data are compared to the avail...
