Rasulov, Suleiman M. published the artcilePpT and liquid-gas phase transition properties (PS,pS,TS) of binary n-hexane + methyl octanoate mixture near the critical point of pure n-hexane, Recommanded Product: Methyl octanoate, the main research area is hexane methyl octanoate binary mixture liquid gas phase transition.
PÏT and phase transition properties (PS,ÏS,TS) of the dilute binary mixture of n-hexane + Me octanoate have been studied near the critical point of pure n-hexane (solvent). The measurements were performed along 11 liquid, vapor and near-critical isochores between (39.3 and 621.1) kg·m-3 over a temperature range from (293 to 622) K at pressures up to 17.7 MPa for the fixed concentration of x = 0.088 mol fraction (or 0.05 mass fraction) of Me octanoate. The measurements were made using a constant-volume piezometer technique. The study was concentrated in the single – and two- phase regions near the critical point of pure n-hexane to precisely determine the phase boundary properties (PS,ÏS,TS) and the critical property (PC,ÏC,TC) data of the mixture The measured critical property data for the mixture were used to study of the isomorphic critical behavior of strongly singular properties such as isothermal compressibility KTX and isobaric heat capacity CPX along the critical isochore and the critical isotherm, i.e., Fisher renormalization (mixture-like behavior) of the critical exponent, -γγ/(1 – α), for strongly singular properties of mixture under study. The measured PÏT data were also used to estimate the values of phys. meaningful (theor. important) parameters such as characteristic reduced temperature Ï1and d. differences ÎÏ1 of the mixture We found that KTX and CPX of the studied mixture exhibit pure-like behavior along the critical isochore at temperature above 508.52 K (slightly above the critical temperature of pure n-hexane, 507.44 K) and along the critical isotherm at densities above 279.82 kg·m-3 (above the critical d. of pure n-hexane, 232.8 kg·m-3). The measured data were used to estimate the Krichevskii parameter Kkr,structural (Nexc)and volumetric (Vâ?) properties of the dilute mixture near the critical point of pure solvent (n-hexane).
