Calculation of the thermodynamic functions of liquid n-alkyl acetates and their binary mixtures with n-butanol

The contributions of molecular interactions to the thermodynamic functions of individual n-alkyl acetates and their mixtures with n-butanol were calculated. It was established that the contributions of molecular interactions to the Helmholtz energy, the internal energy, and the entropy are linear with the molar weight of n-alkyl acetates. For n-butanol-n-alkyl acetate solutions, the contribution to the Helmholtz energy is also linear with the molar weight of n-alkyl acetates and their molar fraction. The corresponding correlation relations are reported.
