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 about 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 from 278.15 K to 328.15 K at atmospheric pressure by the gravimetric method. The experimental values shown that elevated temperatures increased the solubility of buprofezin in all selected Buchowskie-Ksiazaczak solvents. The model, Redich-Kister h modified Apelblat model, (CNIBS/R-K) the model, Jouyban-Acree model, ideal model were used to describe and predict the diversification trend of solubility.
