Abstract: Distn. and (dis)continuous rectification of mixts. in closed chambers, by partially evapt. and condensing the boiling mixt. by press. raising and lowering pulses. The required temp. gradient of the mixt. for ensuring the approach to the b.pt. at all places in the direction of transport through the working chamber is maintained by measured, superimposed heating and cooling zones in the working chamber.
