Provided is a catalyst for partial oxidation of methylbenzenes comprising the compound represented by the following formula 1 and, optionally, a fire-resistant inorganic support:
WO
x
(1)
where W stands for a tungsten atom, O stands for an oxygen atom and x is a number determined by the oxidation state of W. Also provided is a method for producing aromatic aldehydes from partial oxidation of methylbenzenes in gas phase using molecular oxygen using the afore-mentioned catalyst. The catalyst of the present invention can be prepared easily compared with conventional multi-component oxide catalysts. And, aromatic aldehydes can be produced from methylbenzenes with high selectivity and yield.
提供了一种用于部分氧化甲基苯的催化剂,包括以下式子1所表示的化合物,以及可选的防火无机载体:WOx(1),其中W代表
钨原子,O代表氧原子,x是由W的氧化状态确定的数字。同时提供了一种利用分子氧在气相中进行甲基苯的部分氧化制备芳香醛的方法,使用上述催化剂。与传统的多组分氧化物催化剂相比,本发明的催化剂可以更容易地制备。而且,可以高选择性和产率地从甲基苯中生产芳香醛。
