description The invention provides ano-chloroaniline preparation method, wherein the raw materials comprise: o-nitrochlorobenzene, a catalyst, dicyandiamide, a solvent, nitrogen and hydrogen. According to the invention, Ru/C is used as the catalyst, and has characteristics of simple components, stable activity and high selectivity, and dicyandiamide is used as the dechlorination inhibitor, so that the dechlorination side reaction is effectively inhibited, the conversion rate is high, and the selectivity is high; by improving the structure of the rectifying tower, the vapor-liquid mass transfer performancein heat transfer and mass transfer is improved, and the contact area between the gas phase and the liquid phases is increased by utilizing the auxiliary member; the turbulent flow degree is effectively increased through the inflow weir having the step structure and the turbulent flowblock, so that the mass transfer and heat exchange efficiency and the mass transfer and heat exchangerate between the gas phase and the liqu
