The recovery of acetic acid from aqueous solution of glyoxal has been studied experimentally by solvent extraction. The mixed solvents is adopted for the extaction of acetic acid. The extractant consists of tributyl phosphate (TBP) and trioctyl amine (N235) and Kerosene (Ker) with the volume ratio is TBP∶N235∶Ker=50∶20∶30. The suitable operation conditions is the solvent feed ratio S/F=1.3/1 and the theoretical stage number N=4.
