HEAT-CAPACITIES AND DENSITIES OF LIQUID NORMAL-OCTANE, NORMAL-NONANE, NORMAL-DECANE, AND NORMAL-HEXADECANE AT TEMPERATURES FROM 318.15-K TO 373.15-K AND AT PRESSURES UP TO 10-MPA

Heat capacities and densities of liquid n-octane, n-nonane, n-decane, and n-hexadecane have been measured at temperatures from 318.15 K to 373.15 K and at pressures up to 10 MPa using a d.s.c. and a vibrating-tube densimeter, respectively. Both molar heat capacities Cp,m and molar volumes Vm (derived from densities) have been fitted simultaneously as double power series satisfying the relation: (∂ Cp, m / ∂ p)T = - T (∂2 Vm / ∂ T2)p . The results have also been compared with experimental literature values. © 1991 Academic Press Limited All rights reserved.
