Abstract

We report the experimental studies of phase transitions in [xH2O + (1 − x) C7H16] system with x = 0.295 mol fraction (m.f.) of polar component. The temperatures of the phase transitions Ts and the phase equilibrium lines ρ(T) have been obtained from the isochoric heat capacity measurement experiment. The measurements has been made on 12 isochores ρ = const in the density range of 170.0 ≤ ρ ≤ 416.7 kg m−3 and temperatures up to 533 K for given composition x = 0.295 m.f.
