Graphic model for calculating the entropy of С11Н24 alkanes with allowance for multiple non-valence interactions through three atoms along the chain of a molecule

Resumo

A fourteen-constant graphic scheme is proposed for evaluating the thermodynamic properties of branched paraffin hydrocarbons. Absolute entropy S_{f, 298 gas} of 159 alkanes, of which 157 alkanes have yet to be studied experimentally, are calculated using 105 experimental data S_{f, 298 K, gas} for alkanes CН₄–С₃₂Н₆₆.
