由于硫酸水溶液中气相的精确组成无法通过实验获得,因此描述了一种从液相偏摩尔热力学量开始计算水、硫酸和三氧化硫分压的方法。提供的图表和表格给出了-50°至400°C、10至100wt%之间的分压。 %酸。
Because the precise composition of the vapor phase over aqueous sulfuric acid is not accessible experimentally a method is described for calculating the partial pressures of water, sulfuric acid, and sulfur trioxide starting from liquid‐phase partial molal thermodynamic quantities. Graphs and tables are provided which give the partial pressures from −50° to 400°C., between 10 and 100 wt. % acid.
