Abstract A static method has been used to obtain vapor–liquid equilibrium data for the systems ammonia (NH3)–water (H2O)–potassium hydroxide (KOH) and ammonia–water–sodium hydroxide (NaOH) at temperatures of 303 and 318 K and pressures from 0.1 to 1.3 MPa. The salt concentration in the liquid phase was chosen in the range from 2 to 60 mass% salt in water. In both systems NH3–H2O–NaOH and NH3–H2O–KOH, solid–liquid–vapor equilibria were observed. In the NH3–H2O–KOH system, liquid–liquid–vapor equilibrium was observed at 318 K and 1.1 MPa but at yet unknown concentrations of the liquid phases.
