采用ＢＥＴ，ＸＲＯ，ＩＲ和ＥＳＲ等测试手段，考察由４种不同的方法（ＰＶ＝１．１５）制备的ＶＰＯ催化剂的比表面、晶相组成和表面状态，以及用于正丁烷制顺酐反应的催化性能。研究表明，影响顺酐收率的主要因素是催化剂的相组成及钒的氧化态。在（ＶＯ）２Ｐ２Ｏ７相中含有少量α－ＶＯＰＯ４相对丁烷氧化制顺酐有良好的催化效果。有机溶剂的使用能增大催化剂表面积，但并不一定改变催化活性。
- Abstract:
-
Adopting test methods such as BET, XRO, IR, and ESR, the VPO catalysts prepared by 4 different methods (Pv = 1.15) are examined. Studies have shown that the main factor affecting the income of catalysis is the composition of the catalyst and the oxidation state of the catalyst. In the (VO) 2P2O7 phase, it contains a small amount of α -VOPO4, which is relatively catalytic. The use of organic solvents can increase the surface area of the catalyst, but it does not necessarily change the catalytic activity.
