-
Paragraph 0011, (2018/09/21)
The invention relates to a preparation method of 2-aminoazo aromatic compound. The 2-aminoazo aromatic compound is prepared by enabling an azo aromatic compound of a structure which is as shown in theformula I and amine to react; the reaction process comprises the following steps: directly adding the azo aromatic compound, the amine, a catalyst and a solvent into a reacting device, wherein the catalyst is copper acetate, the solvent is benzene, or dimethylbenzene and a mixture of the benzene or the dimethylbenzene, and the molar using amount of azobenzene is 1 to 3 times that of the amine; stirring and heating to the temperature of 100 to 130 DEG C, reacting for 24 hours, and separating a product to obtain the 2-aminoazo aromatic compound. The preparation method provided by the inventionis simple in synthesis route, low in raw material cost and high in yield.
