| Abstract: | The liquid-liquid equilibrium(LLE)of ethyl acetate-acetic acid-water system was studied under different mag-netic induction intensities of 0.165 T,0.310 T and 0.515 T using a liquid-liquid equilibrium device.The results showed that the magnetic field has a positive effect on the LLE of the system,namely the magnetic field could improve the equilibrium constant and be helpful to the separation of the acetic acid-water system.The NRTL equation was used to correlate the LLE data.The influence coefficient of magnetic field on the LLE of ethyl acetate-acetic acid-water was presented. |
