Conclusions
-
1.
The enthalpy and entropy differences for the formation of 1-alkenes, as well as n-olefins with a double bond in an internal position in the cis and trans forms, as a result of the dehydrogenation of C10-C15 n-paraffins under standard conditions have been calculated.
-
2.
Relations for the calculation of the thermodynamic parameters of the reactions (the enthalpy and entropy differences) from group contributions have been derived. Satisfactory agreement between the results obtained on the basis of the calculated and reference data has been demonstrated.
-
3.
The enthalpy and entropy differences for the formation of n-olefins are practically not dependent on the length of the hydrocarbon chain and are determined by the position of the double bond in the molecule of the n-olefin.
