Abstract
In this investigation, the mutual solubilities for ternary 2-nitrobenzoic acid-3-nitrobenzoic acid-acetone system were measured at 283.15 K and 313.15 K, respectively. Two partial isothermal phase diagrams of the system were constructed on the basis of the measured solubilities, one at 283.15 K and the other at 313.15 K. The phase diagrams of the ternary system are similar at the different temperature. Two solid phases were formed and confirmed by the Schreinemaker’s wet residue method, and the two were identified as 2-nitrobenzoic acid and 3-nitrobenzoic acid. The crystallization regions of 2-nitrobenzoic acid and 3-nitrobenzoic acid increase as the temperature decreases.

Notes
This is the unit for the scale on a Siemen’s meter.
This method for determining a tie-line is only valid if no mutual solubility in the solid acids exists.
