“…The behaviour of the binary mixtures presented in this work is different from the observed for the mixtures containing 1-pentanol instead of 2-pentanol already published [3]. First, vapour pressure of the pure compound changes increasing from 0.905 kPa for 1-pentanol to 2.295 kPa for 2-pentanol at T ¼ 313.15 K. Futhermore, the properties of their mixtures with the same hydrocarbons change, for example, no Table 7 RedlicheKister parameters, standard deviation of excess molar enthalpies, s, and, absolute maximum deviation ð DH E m;max Þ for the studied systems.…”

“…Therefore, it is necessary to study the characteristics of mixtures of alcohols with normal, cyclic and aromatic hydrocarbons. In [1][2][3][4][5][6], 1-pentanol and 2-pentanol are considered as oxygen-containing additives to fuel due to such properties as high octane number and high heat of combustion. As the hydrocarbon, n-hexane, cyclohexane or toluene was chosen.…”

Abstract: Primary and secondary alcohols, obtained as a product of processing of plant raw materials, can be used as additives in fuel. Mixtures of n-alkanes, cyclic alkanes and aromatic hydrocarbons can act as a model for gasoline and diesel fuel. Therefore, it is necessary to study the characteristics of mixtures of alcohols with normal, cyclic and aromatic hydrocarbons. To simulate liquid-solid and liquid-vapor phase equilibria, a method is used to minimize excess Gibbs energy by the solvation parameter. The authors developed the PCEAS (Phase Charts Eutectic and Azeotropic Systems) software. The input data in the case of constant pressure are the temperature T 0 and the enthalpy of the phase change 0 H  of the pure components. Prediction of the thermodynamic parameters of secondary alcohols is used to calculate the eutectic and azeotropic parameters of the secondary alcohol -n-alkane mixture: composition, temperature, melting enthalpy and evaporation. The model makes it possible to determine the average value of the association parameter in the liquid phase k. Experimental data for azeotropic mixtures made it possible to establish the association parameter in the vapor phase  of the systems under study. The results of calculations can be used to select the optimal composition and obtain the required characteristics of biofuel.
