ABSTRACT
The isobaric method was used to determine the bubble point pressure of the solutions of H2SiF6 (1) + H2O (mass fraction, w1 = 0.003 to 0.006) and H2SiF6 (1) + CO(NH2)2 (2) + H2O (w1 = 0.003 to 0.006, w2 = 0.004, 0.012, and 0.020) from 323 K to 353 K. The experimental results indicated that the relationship between bubble point pressure Pv and the temperature T can be fitted as the following equation: log(Pv/kPa) = A + B/(T/K).
