中文摘要：

为研究壳聚糖接枝四（对-羧基苯基）钴卟啉（Co TCPP）的催化性能,采用酰化反应方法制备了壳聚糖接枝四（对-羧基苯基）钴卟啉（Co TCPP-CTS）催化材料,用紫外可见光谱仪（UV-vis）、傅里叶变换红外光谱仪（FT-IR）、X射线扫描仪（XRD）、热重分析仪（TG）和透射电镜（TEM）技术对其进行表征,并用于催化空气氧化乙苯研究。催化结果表明：在最佳反应条件下（140℃,0.8 MPa）,含有0.3 mg的Co TCPP Cl的壳聚糖固载四（对-羧基苯基）钴卟啉可以重复催化4次,反应时间2.5 h,乙苯转化率平均为10.4%,醇酮选择性平均为85.6%,醇酮产率平均为8.86%。这说明此催化材料保持了原有Co TCPP Cl的催化活性,并能高效重复使用。壳聚糖是一种良好的载体,在催化反应过程中对金属卟啉有良好的保护和促进作用。

英文摘要：

To investigate the catalytic performance of chitosan grafted cobalt tetra（ p-carboxylphenyl） porphyrin（ Co TCPP-CTS）,Co TCPP-CTS was prepared by an acylation and was characterized by UV-Vis,FT-IR spectra,X-ray diffraction（ XRD） pattern,thermoanalyser（ TG） and transmission electron microscope（ TEM）. The material was used as a catalyst for oxidation of ethylbenzene.The experimental results show that under the optimal oxidation conditions（ 140 ℃ and 0. 8 MPa）,a quantity of the catalyst containing 0. 3 mg of Co TCPP Cl could be recycled for 4 times. On average,the ethylbenzene conversation rate,the selectivity（ acetophenone and phenylethanol） and the yield（ acetophenone and phenylethanol） are 10.4%,85.6% and 8.6%,respectively,indicating that the catalyst material contains the original activity of the cobalt porphyrin and can be efficiently recycled,and chitosan is a good support for protecting and promoting the cobalt porphyrin for the catalysis of ethylbenzene oxidation.
