Solid-liquid equilibrium in the acetic acid-acetophenone and acetic acid-formamide systems

Solid-liquid equilibrium in the binary systems acetic acid-acetophenone and acetic acid-formamide was determined from time-temperature cooling and warming curves. The first system shows a sagged curve with a eutectic point at x1 ≅ 0.6 and T = 267.18 K. In the second system a solid compound (2:1) was found and an equilibrium constant of the compound dissociation was calculated.
