　　为研究多孔壳聚糖金属卟啉选择催化氧气氧化甲苯的能力，以壳聚糖通过盐键和配位键固载四（p-磺酸钠苯基）锰卟啉，用UV-Vis和FT-IR波谱技术、TEM 和TG对该催化材料进行结构表征，在无外加溶剂和助催化剂条件下探索其催化性能。结果表明：在优化反应条件（温度180℃，压力0.8MPa）下，多孔壳聚糖四（ p-磺酸钠苯基）锰卟啉催化氧化甲苯的转化率为15.3％，醛醇产率5.5％，多孔壳聚糖四（ p-磺酸钠苯基）锰卟啉对甲苯的催化效能分别比无孔壳聚糖四（对-磺酸钠苯基）锰卟啉和四（对-磺酸钠苯基）锰卟啉的提高了16.8％和49.3％。壳聚糖通过盐键和配位键固载金属卟啉提高了金属卟啉的重复使用性能，并增强了催化甲苯的能力。

To study the catalysis performance of porous chitosan supported tetrakis [ 4-( sodium sul-fonato) phenyl]porphyrin manganese complex [Mn TPPS/CTS(p)]for aerobic oxidation of toluene, tetrakis-[4-( sodium sulfonato ) phenyl ] porphyrin manganese was anchored onto chitosan by salt bond and coordinated bond .The catalyst complex was characterized by UV-Vis and FT-IR spectro-metry, TEM and TG.Mn TPPS/CTS(p) was used as catalyst for toluene oxidation in absence of solvent and reductant .The experimental results show that toluene oxidation by Mn TPPS /CTS ( p) was 15.3%with a yield of aldehyde at 5.5% under the optimal reaction conditions of 180 ℃ and 0.8 MPa.Catalytic efficiency of Mn TPPS/CTS ( p) is 16.8% and 49.3% higher than those for Mn TPPS/CTS (nonporous) and Mn TPPS, respectively.It is thought that the salt bond and coordi-nated bond probably improves the catalytic activity and the recycle for Mn TPPS .
