Abstract:
Aromatic compounds in combination with aliphatic create azotropic mixture which thoseextraction is one of petrochemical and refinery companies challenging issue [1-2]. In this study, Nformylmorpholine(NFM) in industrial grades has been selected for azotrop point breaking agent.The liquid - liquid extraction properties were measured for several ternary systems containing(hexane + benzene + NFM) at T = (303.15 to 343.15) K and atmospheric pressure. Evaluation ofextraction efficiency has been done by determination of experimental selectivity (S) anddistribution coefficients (β) factors. The NRTL and UNIQUAC thermodynamic models havebeen used to correlate experimental LLE data. The Hansen solubility parameters were calculatedand it were in agreement with solubility test results. The results indicate high selectivity ofstudied solvent (NFM) for benzene extraction from n-hexane phase.
