The invention discloses a layering box and method for preparing 3-chloro-2-methylaniline, and relates to the technical field of chemical equipment.The layering box comprises a box body assembly, a stirring assembly, a layering assembly and a feeding assembly.The method comprises the following steps of raw material injection, auxiliary material dropwise adding, product layering and product extraction.The box body assembly is arranged, and the stirring assembly is arranged in the box body assembly; the stirring assembly and the layering assembly are arranged in the box body assembly, a raw material solution of 3-chloro-2-methylaniline can be put into the box body assembly and is mixed and stirred under the action of the stirring assembly, and in the stirring process, the solution reacts to separate out 3-chloro-2-methylaniline, so that the 3-chloro-2-methylaniline is separated out. At the moment, the layering assembly conveys the 3-chloro-2-methylaniline product in the solution to the uppermost layer, so that t
