Abstract:

Dehydroabietylamine 4-aldehyde phenyl methacrylate schiff base (DAAPMSb) was firstly synthesized
from dehydroabietylamine and 4-aldehyde phenyl methacrylate through nucleophilic additional reaction. The polymerdehydroabietylamine
schiff base (poly(DAAPMSb-co-MAA-co-EDMA)) was then prepared by co-polymerization
reaction using dimethacrylate glycol ester as cross-linker. Polymer dehydroabietylamine schiff base copper complex
(poly(DAAPMSb-co-MAA-co-EDMA)Cu) was finally generated by reacting poly(DAAPMSb-co-MAA-co-EDMA) with
anhydrous cupric acetate and used to catalyze the oxidation of anise oil. Factors influencing the conversion ratio of anise
oil by catalytic oxidation including reaction temperature, time and catalyst dosage were studied systematically. The results
showed that when the conversion of 5.00 g of anise oil catalyzed by 0.14 g of the synthetic catalyst took place for 4 h at
80 ℃ in 30 mL of 1,4-dioxane after dropwise addition of 18 mL of 30% H2O2, the anise oil was oxidized to anisaldehyde as
main product with a conversion rate of 97.49%.
