Summary:PURPOSE: A method for producing a nitrosobenzene having a particular chemical structure from aromatic amine is provided by means of catalytic oxidation using hydrogen peroxide by an industrial simple method without addition of solvent. CONSTITUTION: The method for producing nitrosobenzene defined as the following formula (wherein R1 and R2 are same or different, exhibit any one selected from hydrogen, C1-C4 alkyl or C1-C4 alkoxy) is carried out by oxidizing hydrogen peroxide in the presence of a tungsten compound-based and/or a molybdenum compound-based oxidation catalyst at 5-25 deg.C without using an organic solvent in the ratio of (aromatic amine):(hydrogen peroxide):(oxidation catalyst) of 1:(2.0-5.0):(0.001-0.05). The aromatic amine is preferably aniline, o-, m- and p-toluidine or o-, m- and p-anisidine, more preferably, is aniline. 본 발명은 유기 용매를 첨가하지 않고, 텅스텐 및(또는) 몰리브덴 화합물 기재의 촉매의 존재하에 과산화수소로 산화시킴으로써 방향족 아민으로부터 니트로소벤젠을 제조하는 방법을 제공한다.
