Excess molar heat capacities for (decan-1-ol+n-heptane) at temperatures from (290 to 318)K. Experimental results and theoretical description using the ERAS model

Thermodynamic and acoustic properties of (heptane+dodecane) mixtures under elevated pressures

“…The depolarised Rayleigh scattering in the liquid state of longer chain alkanes (n > 8) indicates the presence of short-range orientational order between the segments of neighbouring molecules (8) and (9)). c Taken from Dzida and Góralski [37]. [46].…”

“…The polynomials reported by Dzida and Góral-ski [37] and by Khasanshin et al [33] were used for heptane and dodecane, respectively. The heat capacities of binary mixtures, C p , were calculated from the thermodynamic relationship:…”

“…The heat capacity of (alcohol + alkane) mixtures is useful for the understanding of the self-association of alcohol molecules in solutions [7,[9][10][11][12][13][14][15][16]. Mixtures of alkanols with alkanes are liquid systems most frequently studied under atmospheric pressure.…”

Second-Order Derivatives of the Gibbs Energy for Liquid Mixtures of Alcohol + Heptane at Pressures up to 100 MPa

“…of sound at elevated pressures were used [4][5][6][7], together with densities [5][6][7] and heat capacities [7][8][9] at atmospheric pressure. The uncertainties of the measured speeds of sound under atmospheric and high pressure were estimated to be better than 0.5 m · s −1 and 1 m · s −1 , respectively.…”
