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.
