摘　　要：为研究Salen-卟啉配合物催化氧化DBDO木素模型物,合成了DBDO木素模型物,以木素模型物为反应物。利用红外光谱和气相色谱-质谱(GC-MS)分析木素模型物在Salen-卟啉配合物催化氧化下的降解产物,依据催化氧化后的DBDO木素模型物降解产物,发现Salen-卟啉配合物的催化氧化能使DBDO木素模型物中Cα-Cβ、α-O-4、β-O-4联接断裂,并且使甲氧基减少,产生了香兰素、苯酚、苯甲醛等降解产物。In order to study Salen-porphyrin complexes catalyze the oxidation of dibenzodioxiaino lignin model compound, lignin model of dibenzodioxiaino was synthesized. The degradation Salen-porphyrin complex catalytic oxidation were analyzed by FT-IR and GC-MS. The degradation of lignin model compound was elucidated based on the degradation products. Salen- porphyrin coroplex catalytic oxide make the Cα-Cβ,α-O-4,β-O-4 linkage broke, and methoxy reduced, generatedvanillin, phenol, anisaldehyde and other degradation products. Keywords： dibenzodioxaino lignin model compound; Salen-porpyrin complex; degradationproduct
