Abstract
The enthalpies of dissolution of 3,4β-epoxyarglabin C15H18O4 are measured via isothermal calorimetry at lactone: 96% ethanol molar ratios of 1: 6000, 1: 12000, 1: 24000 at 298.15 K. The standard enthalpy of dissolution of C15H18O4 in 96% ethanol is calculated from the obtained data; the value is 40.1 ± 0.4 kJ/mol. The enthalpies of combustion, melting, and formation of 3,4β-epoxyarglabin C15H18O4 are estimated by approximate means.
