Abstract:Wastewater containing DMF (N,N-dimethylformamide) and salt is generated
in production of many chemicals
and medicines. The composition of phase equilibrium should be known
primarily for the recovery of DMF from salt-containing wastewater
by solvent extraction. In this study, liquid–liquid equilibrium
(LLE) and solubility data of water + DMF + chloroform in the presence
of NaCl with various concentrations of 0, 2.5, 5.0, 7.5, 10.0, and
13.3 wt % and Na2SO4 with concentrations of
1.5 and 2.5 wt % were determined… Show more
