摘要：

The solubility of 40-bromomethyl-2-cyanobiphenyl (OTBNBr) in binary solvent mixtures of {acetone + (ethanol, n-propanol, and n-butanol)} was experimentally determined within the temperature range 278.15-313.15 K by using a gravimetrical method under atmospheric pressure (P = 0.1 MPa). The results show that the solubility of OTBNBr monotonously increases with increasing temperature and increasing mole fraction of acetone. The solubility of OTBNBr was correlated by the modified Apelblat equation, the van't Hoff equation, and the CNIBS/R-K model. The Akaike's Information Criterion (AIC) was used to choose the best model for correlating the solubility of OTBNBr. The preferred model is the modified Apelblat equation which has the lowest AIC value. Furthermore, the mixing thermodynamic properties (enthalpy, entropy, and Gibbs energy) of OTBNBr were also calculated in the selected solvent mixtures. (C) 2016 Elsevier Ltd.
