ABSTRACT

The solubilities of phenothiazine in water, ethanol, and propylene glycol were measured at (298.2 to 338.2) K. Also, the solubility of phenothiazine in binary mixtures of ethanol + water, propylene glycol + water, and ethanol + propylene glycol, and the ternary mixture of ethanol + propylene glycol + water was investigated. The van't Hoff equation was used to correlate the solubility of phenothiazine in monosolvents at different temperatures. The solubility values of phenothiazine in binary and ternary mixtures of solvents were calculated using the Jouyban Acree model (Jouyban, A.; Acree, W. E., Jr. J. Chem. Eng. Data2009, 54, 1168 1170). The mean deviation was used as an error criterion. The overall mean deviation of correlated solubility data in monosolvents at different temperatures and in mixed solvents at 298.2 K were 2.8 % and 14.2 %, respectively.
