The invention belongs to the field of fine chemical engineering, and particularly relates to a method for recycling 3,3'-imido-bis(N,N-dimethyl propylamine) from industrial byproduct heavy components of N,N-dimethyl-1,3-propane diamine. The method comprises the following steps: recycling DMAPA by distillation; recycling bis-DMAPA by distillation; continuously and repeatedly recycling and the like; finally purifying and recycling a solvent from a residual distillation solution. By adding a suitable organic solvent for distillation, the method disclosed by the invention can be used for efficiently recycling DMAPA and bis-DMAPA in the DMAPA heavy components. By adding a proper amount of the solvent, the viscosity of the heavy components can be reduced, the fluidity of the liquid can be increased, and high-efficiency recycle of the bis-DMAPA in the heavy components is facilitated; besides, a part of the solvent can be recycled to lower the production cost.
