The invention relates to a process for preparing aminoanisole and
aniline by taking a mixture of a nitroanisole and
nitrochlorobenzene as a
raw material. The process comprises the following: (1) a step of the
catalytic hydrogenation reaction and the catalytic dechlorination reaction, during which,
methanol is taken as a
solvent, the mixture of the nitroanisole and the
nitrochlorobenzene is taken as the
raw material, catalyst is added,
hydrogen is aerated; (2) a step of the
solid-liquid separation, during which,
solid and liquid in the material obtained from the step (1) after the
catalytic hydrogenation reaction and the catalytic dechlorination reaction are separated, a
liquid phase comprises aminoanisole,
aniline,
methanol,
hydrochloride and water and is utilized in the next step; (3) a step of the liquid-liquid separation, during which, the
oil phase-water phase liquid-liquid separation is performed in the material obtained in the step (2), the aminoanisole and
aniline in the
oil phase is utilized in the next step; (4) a step of
distillation separation, during which, the
distillation separation is performed in the
oil phase to produce products of paraphenetidine, ortho-anisidineand aniline. The process for preparing the aminoanisole and the aniline has the advantages that: (1) the cost is low, the preliminary treatment step is saved, the process is simple; (2) the process is clean, the
energy consumption is low, the 'three wastes' are little; (3) the purity of the product is high.
