An apparatus for measuring solubilities of gases in liquids at elevated temperatures and pressures has been constructed. Using this apparatus, the slubilities of N_2 and CO_2 in some solvents have been determined in the temperature range between 20 and 230℃, and at pressures up to 130 atm. The experimental results obtained generally agree well with literature values. It is shown that this apparatus is reliable; attainment of equilibria needs only about 5 hours; precision of the measure- ments is ±0.2%. 展开更多
