For evaluation of their extractive properties, the authors studied liquid-liquid equilibria in water-cyclohexanone (CH), ethyl acetate (EA) extraction systems. With the use of toluene as the extractant, the CH and EA contents in both coexisting phases, extract (C /SUB e/ ) and aqueous (C /SUB w/ ), were determined chromatographically. In systems with diesel fuel, the CH and EA contents in the extract phase were calculated from thier concentrations in the aqueous phase, determined chromatographically. Technical and economic calculations show that the energy costs for purification of water and recovery of CH and EA by the proposed method are lower by a factor of 1.8-2.0 than by the use of azeotropic distillation.
