The utility model relates to a distillation teaching system, including stills, condenser, stills, condenser are connected with the condenser through first pipeline, establish the heating wire in the stills, and the condenser still is connected with a plurality of solvent storage unit through the second pipeline, and solvent storage unit includes the accumulator, and the accumulator is the closed,and priming pump all through third pipeline and stills intercommunication, is established through first by -pass line and the 2nd pipeline connection, each accumulator to the accumulator on the thirdpipeline. The utility model discloses simple structure easily builds in the laboratory, and the solvent after collecting the distillation condensation simultaneously carries out cyclic utilization, has practiced thrift the cost.
