ABSTRACT
Vapor-liquid equilibria of ammonia + water + potassium hydroxide and ammonia + water + sodium hydroxide systems were measured by a static method from (293.15 to 353.15) K. The experimental vapor pressure data have been correlated with temperature and mass percent concentration using an analytical polynomial equation.
