RECEIVER OF VACUUM CHAMBER REACTOR OF SYNTHESIS OF GLYCOLIDE AND LACTID Russian patent published in 2017 - IPC C07D319/12 B01D5/00 C07D319/10 

FIELD: chemistry.

SUBSTANCE: receiver of the vacuum chamber reactor for the synthesis of glycolide and lactide is a container with three heat exchange loops, 220-260°C at the point of entry of the vapor-gas mixture, 90-130°C in the outer peripheral annular cavity of the apparatus containing a system of steel tubes filled with a heat carrier, 70-110°C at the top of the receptacle for re-trapping monomer vapors, and a product collector at the bottom of the apparatus supporting the monomer in a melt state at a residual pressure of 1-5 mm Hg.

EFFECT: device ensures the condensation of the raw monomer.
