Abstract

The heat of vaporization (∆vapНo), all thermodynamic functions ∆с,fGo, ∆с,fHo, So, ∆cSocond and heat capacity (Cp) of organic compounds of V-VII groups of Mendeleev′s Periodic Table can be well characterized with the number of valence electrons N without taking into account the number (h) of lone electrons pairs (g) of them in equation vap,c,f,sΨo = i ± f *(N - hg). The stoichiometric coefficients i and f reflect partially a various spatial structure of all investigated compounds. The free energy and entropy of combustion and formation are calculated only for oxygen, sulfur and partly fluorine compounds. For this reason their analysis causes the certain difficulties. It is possible to note, that f coefficients in the given above equation for free energies of combustion are very close to such coefficients for the heat of combustion processes. Also it has been found that calculated thermodynamic functions of ethers and sulfides are in good interdependence from each other: ∆сНo - ∆сSocond, ∆fНo - Socond, Socond - Cp. The 74 equations of mentioned type have been created for processes of vaporization, combustion, formation, entropic transformations and heat capacity.

The free energy and entropy of combustion and formation are calculated only for oxygen, sulfur and partly fluorine compounds. For this reason their analysis causes the certain difficulties. It is possible to note, that f coefficients in the given above equation for free energies of combustion are very close to such coefficients for the heat of combustion processes. Also it has been found that calculated thermodynamic functions of ethers and sulfides are in good interdependence from each other: ∆сНo - ∆сSocond, ∆fНo - Socond, Socond - Cp. The 74 equations of mentioned type have been created for processes of vaporization, combustion, formation, entropic transformations and heat capacity.
