| description | PURPOSE: Provided is a method for producing an aminodiphenylamine useful for leading a product from aromatic amine and nitrohalobenzene to be obtained in high purity and good yield when conducting hydrogenation of the product. CONSTITUTION: The method comprises reacting aromatic amine and nitrohalobenzene in the presence of a palladium catalyst and a basic material and then hydrogenating the obtained product with hydrogen to provide the aminodiphenylamine. The used nitrohalobenzene is featured by having nitro radical on a para-position relative to the halogen residual group. The used aromatic amine is selected from a group consisting of aniline, o-, m- or p-toluidine, 4-ethylaniline, 4-butylaniline, 4-isopropylaniline, 3,5-dimethylaniline or 2,4-dimethylaniline. The nitrohalobenzene and the amine are contained in a mole ratio of 1:1-10mole.
본 발명의 방법에 따른 아미노디페닐아민의 제조는 팔라듐 촉매 및 염기의 존재하에서 방향족 아민을 니트로할로벤젠과 반응시킨 후 얻어진 생성물을 수소로 수소화 반응시킬 경우, 양호한 수율 및 높은 수준의 순도를 야기한다. |
