首次报道了环己酮肟在Ｂ２Ｏ３／ＺｒＯ２催化剂上的气固相Ｂｅｃｋｍａｎｎ重排反应，结果表明该催化剂具有很高的活性（９７．７％）和ε┐己内酰胺选择性（９７．０％）；用Ｈａｍｍｅｔ指示剂正丁胺滴定法测定了样品的表面酸性质，并与催化活性和选择性进行了关联；用ＸＲＤ谱对催化剂结构进行了表征；比较了Ｂ２Ｏ３负载于几种载体上的催化活性和选择性的差异
The gas-solid phase Beckmann rearrangement of cyclohexanone oxime on B2O3 / ZrO2 catalyst was reported for the first time. The results show that the catalyst has high activity (97.7%) and ε┐ caprolactam selectivity (97.0%). The surface acidity of the sample was determined by the Hammet indicator n-butylamine titration method, and its catalytic activity and selectivity were correlated. The structure of the catalyst was characterized by XRD. The catalytic activity of B2O3 supported on several carriers was compared And selective differences
