摘　　要：对负载型铌系催化剂载体的选择进行了研究,选用HZSM-5作为载体效果较佳。采用前沿色谱法、NH3-TPD和CO2-TPD及XRD等多种方法对负载型催化剂进行了表征,能与其催化活性较好地关联。用于乙酸酯类化合物的合成,单程收率可达93%以上,选择性为100%。Selection of carriers for supported niobium series catalyst was systematically studied in this paper. HZSM-5 was the best among carriers of catalyst. This catalyst was characterized by frontal chromatography, NH3-TPD, CO2- TPD and XRD technique, and had a good correlation with its catalytic activity. The single conversion rate and selectivity was above 93% and 100%, respectively, when the catalyst was used to synthesize acetic esters.
