The invention relates to a process for preparing phenetidin and amino phenol by taking a mixture of nitrophenetol and nitrophenol as a raw material. The process comprises the following steps that: (1) a step of the catalytic hydrogenation reaction to a body, during which, the mixture of the nitrophenetol and the nitrophenol 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 are separated, a liquid phase 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), an oil phase is utilized in the next step; (4) a step of crystallization; (5) a step of solid-liquid separation, during which, solid and liquid of the material crystallized in the step four are separated, the solid phase is paraaminophenol and ortho-aminophenol, the phenetidine in the liquid phase is utilized in the next step; (6) a step of distillation separation, during which, the products of para aminophenyl ethyl ether and o-phenetidine are obtained. The process for preparing the aminoanisole and the aniline has the advantages that: the cost is low, the preliminary treatment step is saved, and the process is simple; and the process is clean, the energy consumption is low, and the 'three wastes' are little.
