摘　　要：为了研究Salen-卟啉配合物催化氧化木素模型物,我们合成了Salen-卟啉配合物(Zn PSC6).用由Zn PSC6、吡啶(联吡啶)、H202、Na OH组成的Zn PSC6型仿酶体系对木素模型物藜芦醇进行降解,并用GC-MS对降解产物进行分析.结果表明:Zn PSC6型仿酶体系能专一地催化氧化藜芦醇转化为藜芦醛,并且随着温度的升高,催化氧化效率先升高后降低.当温度为25℃时Zn PSC6、Na OH、H2O2组成的Zn PSC6仿酶体系的转化率最高,转化率为98.7%.In order to study the catalysis of Salen- porphyrin complexes on the oxidation of lignin model compound,a Salen- porphyrin complex（ Zn PSC6） is synthesized. Veratryl alcohol is treated with a novel delignification system containing Salen- porphyrin,pyridine（ 2,2＇- dipyridyl）,hydrogen peroxide and Sodiun hydroxide（ Salen- porphyrin system）. The GC- MS analysis is used to investigate the degradation product of model compound during the reaction. Results show that Salen- porphyrin type biomimetic system has ability to degrade lignin model compound specifically. As the temperature rises,the efficiency of the catalytic oxidation is firstly increased and then decreased. When the temperature is 25 ℃,the conversion of Salen- porphyrin system containing Zn PSC6,pyridine,hydrogen peroxide Sodiun hydroxide is the highest,the conversion rate being 98. 7%.
