Popis: | Distribution constants of water and CL between the vapor phase and solid PCA at 413–463 K have been determined. -- Results of calculations have been given which show that the stage of solid-phase final amidation of PCA can be realized in apparatus which ensures maintaining the pressure in the range 1.1–1.5 MPa; thereupon, the losses of CL because of evaporation into the free volume of the apparatus do not exceed 9 kg per ton of polymer. |
