Solubility Behavior and Thermodynamic Analysis of Bisphenol A in 14 Different Pure Solvents

Abstract

The solubility of bisphenol A in 14 different pure solvents (N,N-dimethylformamide, formamide, acetone, 1,4dioxane, cyclohexanone, ethyl acetate, methyl acetate, acetonitrile, ethanol, methanol, 1-propanol, 1-butanol, 2-propanol, and 2butanol) was measured at T = (273.15−313.15) K under atmospheric pressure using a laser dynamic method. The experimental data of bisphenol A were correlated by modified Apelblat equation, λh equation, nonrandom two-liquid model and Wilson model, and the fitting results showed that the modified Apelblat equation gave the best correlation with the experimental results. The thermodynamic functions of bisphenol A in 14 pure solvents, such as dissolution enthalpy (Δ mix H), Gibbs energy (Δ mix G), and dissolution entropy (Δ mix S), were obtained from the Wilson model. The results of the Δ mix G < 0 and Δ mix H < 0 indicated that the dissolution process of bisphenol A in selected solvents was exothermic and spontaneous. The values of γ 1 ∞ and γ 1 were not close, indicating that bisphenol A in selected solvent solution systems was nonideal.

Measurement and Correlation of Solubility Behavior of Bisphenol A in Binary (Ethyl Acetate + n-Butanol, Ethyl Acetate + 2-Butanol, Ethanol + n-Butanol, and Ethanol + 2-Butanol) Solvents

“…The λ h equation ,− was expressed as where λ and h are the model correlated parameters; the corresponding fitting values are listed in Table . T m is the melting temperature of the solute; the value is 430.83 K …”

“…In addition, the solubility of benzoic acid in toluene was also measured to further verify the reliability of the experimental device. The literature data , and experimental solubility data curves are presented in Figure a,b, and the comparative data are shown in Tables and . The experimental value agreed well with the literature value, which indicated that the experimental method and device were reliable.…”

Upcycling Compact Discs for Bioelectronic Applications

“…The degradation of the substrate initiated the removal of the toxic, hazard monomer from the CD-BPA-producing an eco-friendly, clean recycling treatment for the upcycling process (Supplementary Fig. 5) 28,29 . The metal from the CD was easily harvested with polyimide (PI) tape, which also serves as the substrate layer in the new device integration to improve the mechanical durability and robustness of the thin metal film (Fig.…”
