摘要:

利用脱氢枞胺与甲基丙烯酸-(4-醛基)-苯酯经亲核加成合成可聚合单体脱氢枞胺Schiff碱,该单体与交联剂甲基丙烯酸乙二醇酯共聚制备了脱氢枞胺甲基丙烯酸-(4-醛基)-苯酯Schiff碱高分子,再与无水醋酸铜反应,得到脱氢枞胺Schiff碱高分子铜配合物催化剂。将脱氢枞胺Schiff碱高分子铜配合物催化剂用于催化氧化茴香油,探讨了催化剂用量、反应温度及反应时间对催化氧化茴香油转化率的影响。研究结果表明,在30 mL 1,4-二氧六环为溶剂、5.00 g茴香油、0.14 g催化剂、18 mL 30%的H2O2溶液逐滴加入、反应温度80 ℃、反应时间4 h的氧化条件下,茴香油的转化率达到97.49%。

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%.

Key words: dehydroabietylamine polymer schiff base, complex, catalyst, anise oil
