英文摘要 | Methyl-2-furoate (MF) is a high-value compound, and can be produced via esterification of furoic acid derived from biobased furfural. Herein, CAL-B and [bmim] [PF6] were the most efficient lipase and organic medium for MF production, respectively. Based on mass action law and reaction reversibility, a mathematical model was developed. Data analysis showed the newly proposed binary regression was apparently more suitable compared to the commonly used unitary regression. The enzymatic promotion factor m, for esterification and hydrolysis was 1.8159 and 0, while the alcohol inhibition factor n(i) was 0 and 0.06436, respectively. Both the activation energy E-a,E-i for esterification and hydrolysis was 84 kJ/mol, and the pre-exponential factor A(i) was 7.1408 x 10(13) and 7.8962 x 10(13), respectively. Kinetics study demonstrated that CAL-B held significantly more dominant esterification activity compared to hydrolysis activity, whereas alcohol just inhibited hydrolysis activity instead of esterification activity, and the relationship between esterification/hydrolysis rate constants k(i) and temperature agreed with Arrhenius equation. The maximum MF yield was 82.5 % at 24 h, and the yield decreased to 75.4 % after 1 re-use of CAL-B, but maintained about 20 % for next 4 cycles. Totally, the developed model and binary regression analysis method is ideal for in-depth examination of lipase-catalyzed kinetics in heterogeneous system. |
