The invention discloses a method for preparing 2-butanone by biomimetic catalytic air oxidation of n-butane. According to the method, n-butane is taken as a raw material, air or oxygen is taken as an oxidizing agent, a metal complex is taken as a catalyst, a solvent and a cocatalyst are added, a catalytic reaction is carried out under the conditions that the reaction temperature is controlled to be 50-100 DEG C and the reaction pressure is 0.5-5.0 MPa, and 2-butanone can be prepared with high selectivity. The method has the advantages of mild reaction conditions, good catalytic effect, high conversion rate, simple process and the like; belongs to the technical field of organic synthesis. 本发明公开了一种仿生催化空气氧化正丁烷制备2-丁酮的方法；该方法以正丁烷为原料，以空气或氧气为氧化剂，以金属配合物为催化剂，加入溶剂和助催化剂，控制反应温度为50～100℃，反应压力为0.5～5.0MPa的条件下进行催化反应，可高选择性地制得2-丁酮。本发明具有反应条件温和、催化效果好、转化率较高、工艺简单等优点；属于有机合成技术领域。
