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.
