Thermodynamics of sublimation and solvation for bicyclo-derivatives of 1,3-thiazine

• Temperature dependencies of saturated vapor pressure of new bicyclo-derivatives were obtained.
• Thermodynamic functions of sublimation and solvation were calculated.
• The correlations between thermodynamic functions and molecular descriptors are discussed.

Temperature dependencies of saturated vapor pressure of novel bicyclo-derivatives of 1,3-thiazine with methoxy- and carbonyl-substituents have been obtained by method of transference by means of an inert gas carrier. Thermodynamic functions of sublimation have been calculated. Correlations between thermodynamic functions of sublimation and thermophysical properties of the substances and molecular descriptors have been established. The enthalpies of solvation of compounds were calculated using the measured values of enthalpies of sublimation and of standard enthalpies of solution in hexane and buffer.
