新型Nb2O5催化剂的制备及催化性能的研究
An Investigation on Activity and Preparation of Niobium Oxide Catalyst.
【摘要】 以乙酸和正丁醇催化酯化合成乙酸正丁酯为探针反应 ,对Nb2 O5型催化剂的制备与催化活性进行了一系列的研究 ,得出了优惠的工艺条件。正丁醇的转化率达 95 % ,乙酸正丁酯的选择性 10 0 %。并对催化剂进行了一系列的表征 ,发现其与催化活性能很好地关联。
【Abstract】 Taking the synthesis of butyl acetate by the catalytic esteritification of acetic acid and butanol as a probe reaction, a series of studies on the prepation of the catalyst and its activity was made. The conversion ration of butanol and selectivity of butyl acetate are 95% and 100%, respectively, in the optimal condition. Using different analysis method for catalyst, relations with reaction is very good.
