The liquid–liquid equilibrium
of ternary systems cyclohexene
(cyclohexanone) + water + 1-methylpyrrolidin-2-one (N,N-dimethylacetamide) was studied experimentally
to assess the possibility of separating the mixture of cyclohexanone
production. Bachman and Hand equations were used to test the correlation
of the experimental data. The solubility was measured using a “cloud-point”
technique method, and the data on compositions of liquid phases were
determined by GLC analysis. Experimental data were correlated using
the nonrandom two-liquid model. Calculated results were found to be
in sufficient agreement with experimental data. The topological structure
of the phase diagram is discussed. Recommendations for conducting
a chemical reaction are formulated, and a flowsheet for separating
the reaction mixture is proposed. The efficiency of the flowsheet
is confirmed by the simulation of the distillation process.
