Abstract:: Bisphenolic acid was synthesized by condensation reaction using hydrochloric acid as catalyst, thioglycolic acid as cocatalyst, and levulinic acid and phenol as raw materials. The molar ratio of levulinic acid to phenol, the molar ratio of levulinic acid to hydrochloric acid, reaction temperature and time were selected as follows: reaction temperature 9 °C, reaction time 34 h, n(levulinic acid)∶n(phenol)=60∶45, n(levulinic acid)∶n(hydrochloric acid)=1∶4, n(levulinic acid)∶n(hydrochloric acid)=1∶4, and the yield of bisphenolic acid reached 97.1%.
