Some Equilibrium Relations in the System Calcium Oxide—Sulfur Dioxide—Water (Acid Region) at Pressures below Atmospheric¹

Spectrophotometric measurement of the vapour-liquid equilibria of (sulphur dioxide + water)

“…These results are also in good agreement with the measured ones. (19)(20)(21) Parkinson (22) measured the partial pressures of SO 2 at T = 294.25 K. His values agree within experimental error with our calculations.…”

“…The excellent agreement between the measured (19) at T = 298.15 K; ×, Morgan and Maass (20) at T = 298.15 K; $, Conrad and Beuschlein (21) at T=298.15 K; W, Rabe and Harris (23) at T = 313.15 K; q, Vosolsobe et al (24) at T = 313.15 K; w, Perry and Green (2) at T = 313.15 K; ----, Pearson et al; (4) --, this work.…”

“…(4,18) It may be seen that values quoted by Perry (2) are too high. Figure 5 and 6 compare our results at T = 298.15 K with experimental values (5,(19)(20)(21) and correlations (4,13,18) over a large molality range (up to 1 mol·kg −1 ). In dilute aqueous solutions, the experimental results of Johnstone and Leppla (5) agree very well with our calculated values.…”

Solubility Study of Binary Systems Containing Sulfur Dioxide and Water: A Combination of Raman Spectroscopy and Monte Carlo Molecular Simulation

“…Its solubility is about 100 times higher than CO 2 (Figure 1). Unfortunately, only scarce information is available in the literature [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] for the SO 2 /H 2 O mixtures. Most of the studies were carried out at low pressure and temperature range as shown in Figure 2.…”
