Abstract
The solubility of 2-chloro-3-(trifluoromethyl)pyridine was measured at 273.15 K-303.15 K under atmospheric pressure in methylbenzene, dichloromethane, ethanol, n-propanol, n-hexane, n-heptane and ethanol + 1-propanol binary solvents. The solubility of 2-chloro-3-(trifluoromethyl)pyridine in pure and ethanol + n-propanol binary solvents increases with the increase of temperature. But in ethanol + n-propanol binary solvents, the solubility of 2-chloro-3-(trifluoromethyl)pyridine also increases with the increasing the mole fraction of ethanol. The van't Hoff equation, modified Apelblat equation, λh equation, and Wilson model were used to correlate the solubility data in different pure solvents, and the van't Hoff equation, modified Apelblat equation, and λh equation were used to correlate the solubility data in ethanol + n-propanol binary solvents. In six pure and binary solvents, the thermodynamic properties of the standard dissolution enthalpy, the standard entropy, and the standard mole Gibbs energy were evaluated based on the van't Hoff equation.
