Abstract
Buprofezin is a kind of insecticide and an important chemical intermediate product. Data on solid–liquid equilibrium of buprofezin in different solvents is essential for the area of industrial applications. In this work, the solubility of buprofezin in methanol, ethanol, isopropanol, n-butanol, acetonitrile, n-hexane, ethyl acetate, N,N-dimethylformamide, and two binary solvent mixtures (methanol + ethyl acetate and acetonitrile + ethyl acetate) was measured at the temperature range of 278.15–328.15 K at atmospheric pressure by the gravimetric method. The experimental values showed that elevated temperatures increased the solubility of buprofezin in all selected solvents. The modified Apelblat model, the Buchowski–Ksiazaczak λh model, combined nearly ideal binary solvent/Redlich–Kister (CNIBS/R-K) model, Jouyban–Acree model, and an ideal model were used to describe and predict the diversification trend of solubility.
