Form CO2-responsive microemulsion for extracting ethanol from water by triethylamine

Compared with traditional distillation separation, extraction of ethanol from water could reduce the energy consumption. But emulsion generated in process strong mixing caused difficulty separation two phases. A new method realize efficient mass transfer and complete The microemulsion system was constructed by adding TEA (triethylamine) into water, then extracted 2-ethyl-1-hexanol. efficiency close to theoretical value, be demulsified under action CO2. did not require stirring, had low consumption high efficiency. It solved problem separate extraction.
