摘要: Abstract Phase equilibrium data for methanol + C18 methyl esters and methanol + α-tocopherol were measured at 523–573 K in the pressure ranges of 2.45–11.45 MPa C18 3.19–15.02 MPa α-tocopherol, respectively. The correlated using Peng-Robinson equation state (PR EOS) with conventional mixing rules. distribution coefficients α-tocopherol methanol discussed. illustrate that when is lower than critical (8.097 MPa), mole fractions vapor are very close to unity both systems. When increased over 8 MPa, significantly 548–573 K 573 K. Noticeably, this work firstly reports phase high temperatures pressures.
