ABSTRACT
The solubility of quinacridone in hot-compressed water was measured for the first time at temperatures from (453.4 to 592.9) K and at a pressure of 24 MPa with a flow-type apparatus. The solubility varied from 1.07x10-5 molakg-1 at 453.4 K to 5.89x10-3 molakg-1 at 592.9 K. Dissolution equilibria of quinacridone were analyzed by a simple thermodynamic model on the basis of the measured solubility.
