ABSTRACT
The solubility of -Arbutin (ARB) in 12 different mono-solvents (methanol, ethanol, propanol, isopropanol, butyl alcohol, isobutanol, ethyleneglycol, acetone, 2-butanone, acetonitrile, methyl acetate, ethyl acetate) from 283.15 K to 323.15 K at atmospheric pressure was measured by gravimetric method. The solubility data shows an increasing trend with increasing temperature. The solubility is related to many factors like polarity, H-bond and cohesive energy density etc. The solubility of ARB was correlated by the Apelblat model, h equation, Van't Hoff equation and NRTL model. And the Apelblat model shows a better fitting result compared that with other three models through calculating the value of ARD. Besides, the dissolution thermodynamic properties (the dissolution Gibbs energy, enthalpy and entropy) were evaluated, which reveals that the dissolution of ARB is a spontaneous and exothermic process.
