Resumo
The solid–liquid equilibria (SLE) in the ternary nicotinic acid + ammonium sulfate + water system were experimentally studied at T = 298.15, 323.15, and 348.15 K under atmospheric pressure by an isothermal equilibrium method. Three isothermal phase diagrams of the system were established based on the measured mutual solubility data. Meanwhile, the physicochemical properties (density and conductivity) of this system were measured. The phase diagram contained three crystallization regions, two crystallization curves, and one co-saturation point at each temperature. The crystallization field of both nicotinic acid and ammonium sulfate enlarged with increase of temperature. The crystallization region of ammonium sulfate was smaller than that of nicotinic acid at each temperature.
