(A, B Control experiments for the reaction of MB in the presence of H2 or N2. Reaction conditions: MB (1 mmol), [BMMIm]Br (2 mmol), Pd/C (5 mg, 5 wt% Pd), 5 MPa H2 or 1 MPa N2, 160 °C, 24 h; (C) The hydrogenolysis reaction of 3-bromobutyric acid. Reaction conditions: 3-bromobutyric acid (1 mmol), [BMMIm]Br (2 mmol), Pd/C (5 mg, 5 wt% Pd), 5 MPa H2, 160 °C, 24 h; D Possible reaction pathway for the degradation of polyesters over [BMMIm]Br-Pd/C under the H2 atmosphere. R=H or CH3, m ≥ 0.
