Measurement and thermodynamic modelling of ternary liquid-liquid equilibrium for extraction of (1R,2R)-(−)-1,2-Diaminocyclohexane from aqueous solution with C4–C5 alcohols at different temperatures

Liquid–Liquid Equilibrium Measurement and Correlation for the Ternary Systems (Dimethyl Succinate + 1,4-Butanediol)/(Dimethyl Glutarate + 1,5-Pentanediol)/(Dimethyl Adipate + 1,6-Hexanediol) + Water at Different Temperatures

“…The LLE data for their ternary systems were measured at four different temperatures (293.15, 303.15, 313.15, and 323.15 K) at 101.3 kPa. The reliability of the equipment used in this work has been evaluated in our previous studies in which the details of apparatus and procedures were described. , …”

“…The reliability of the equipment used in this work has been evaluated in our previous studies in which the details of apparatus and procedures were described. 19,20 Experiments were carried out in the double-jacketed glass vessel with a magnetic stirrer to accelerate the two-phase equilibrium, and the temperature was controlled by a thermostatic bath (type, DC4006, Shanghai Bilon Precision Instrument Co., Ltd.). The actual temperature and atmospheric pressure of liquid in the flask were measured by a mercury thermometer [u(T) = 0.2 K calculated from measurement uncertainty u Td = 0.10 K and calibration uncertainty u Tc = 0.17 K] and a manometer [u(p) = 0.62 kPa calculated from measurement uncertainty u pd = 0.36 kPa and calibration uncertainty u pc = 0.5 kPa], respectively.…”
