Solubility data of several solvents in acetic acid separation process

The selection of solvents for acetic acid separation process was investigated with several solvents namely Butyl Butyrate, Benzene, Diisopropyl ether (DIPE), Methyl Iso Butyl Ketone (MIBK), and Ethyl Acetate. The suitable solvent for extracting acetic acid was determined experimentally by cloud point method. As the result of experimental data the hierarchy of selecting the order of the solvent based on two-phase region was given as, Ethyl Acetate > MIBK >DIPE > Benzene > Butyl Butyrate. The solubility data of several solvents were reported and compared.
