Vapor-liquid equilibria for the system ammonia + water up to the critical region

摘要: Bubble points, dew and critical points were measured in the system ammonia+water for several mixtures of constant overall composition by direct observation. Results have been compared with those Muller et al., Rizvi Heidemann, Gillespie al. It is concluded that at lower temperatures pressures four sources reference data present a unique consistent picture vapor-liquid equilibria ammonia+water. At above 473 K, significant deviations exist
