Abstract

Synthesis of deep eutectic solvent(DES) composed of ethylene glycol and choline chloride was studied. The effect of the ethylene glycol choline chloride DES and ethylene glycol extractor on the preparation of fuel ethanol was compared. The effect of extractor amount and reflux ratio of distillation column on ethanol purity in the distillate was investigated respectively. Results indicate when ethanol waten azectrope is used as raw material, ethanol concentration in the column distillate using the deep eutectic solvent is 1.5%~2.6% higher than using ethylene glycol. In addition, higher boiling point of the DES can guarantee an economical and green process, the use of toxic ethylene glycol will be avoided and total energy consumption will be decreased considerably.

Key words： choline chloride ethylene glycol DES fuel ethanol water removal
