Separation of Benzene-Cyclohexane Azeotropes Via Extractive Distillation Using Deep Eutectic Solvents as Entrainers
نویسندگان
چکیده
The separation of benzene and cyclohexane azeotrope is one the most challenging processes in petrochemical industry. In this paper, deep eutectic solvents (DES) were used as for cyclohexane. DES1 (1:2 mix tetrabutylammonium bromide (TBAB) levulinic acid (LA)), DES2 TBAB ethylene glycol (EG)) DES3 ChCl (choline chloride) LA) entrainers, vapor-liquid equilibrium (VLE) measurements at atmospheric pressure revealed that a DES comprised 2:1 ratio LA could break with relative volatility (αij) up to 4.763. Correlation index suggested NRTL modelling approach fitted experimental data very well. Mechanism extractive distillation gained from FT-IR hydrogen bonding π–π bond interactions between be responsible ability entrainer azeotrope.

Application of Extractive Distillation for the Separation of Benzene and Cyclohexane Mixture
Distillation is the most widely used separation technique in the chemical process industries. Not all liquid mixtures can be separated by ordinary fractional distillation, however. When the components to be separated of system have relative volatilities of close to 1.00 (i.e. close boiling mixture), separation becomes difficult and expensive because a large number of trays and a high reflux rat...
متن کاملFunctionalization of graphene using deep eutectic solvents
Deep eutectic solvents (DESs) have received attention in various applications because of their distinctive properties. In this work, DESs were used as functionalizing agents for graphene due to their potential to introduce new functional groups and cause other surface modifications. Eighteen different types of ammonium- and phosphonium-salt-based DESs were prepared and characterized by FTIR. Th...

متن کاملRedox fusion of metal particles using deep eutectic solvents.
Alternating anodic and cathodic current pulses have been applied to a metal powder on an electrode surface to fuse the particles together. It is shown that homogeneous films can be electroformed with different morphologies depending on the size of the powder and the experimental conditions.
