5. Liquid–liquid equilibria of aqueous two phase system containing of PEGDME and (NH4)2 SO4 at different temperatures and its application in partitioning of lactic acid

Mohammed Taghi Zafarani Moattar; Hemayat Shekaari; Tohid Hashemzadeh

Volume 10, Issue 3 , Summer 2020, Pages 125-132

Abstract
  In this work, the liquid-liquid equilibria (LLE) of (PEGDME2000 +ammonium sulphate + water) was studied at T= (298.15, 308.15 and 318.15) K. Furthermore for this system the free energies, enthalpies and entropies of cloud points were calculated at the mentioned temperatures in order to investigate the ...  Read More
