✦ Synopsis
Vapor-Liquid Equilibria for NH3 and H20 in the 100 to 150°C Region: Effect of Low Levels of Phenol on Partial Pressure of Ammonia Experimental results are reported for the partial pressure of ammonia in water solutions containing low concentrations of phenol. Experiments were performed in 0.6 molal phenol at 100 and 150°C. Results at 150°C indicate that the very small effect of phenol on the partial pressure of ammonia is within the limit of experimental error, 3%, and therefore could not be established from the data. However, at 100"C, the partial pressure of ammonia was decreased by nearly 10%. Computer program TIDES-a computerized thermodynamic framework for calculating vapor-liquid equilibria for volatile weak electrolytes and other common gases-has been revised to account for the effect of low concentrations of phenol.
