FIELD: chemical or physical processes.
SUBSTANCE: tower reactor comprises reaction zones for simultaneous esterification and/or ester interchange and preliminary condensation. The top one third part of the tower reactor is made of hydrocyclone (2) with suspended heat exchanger (5) and has inlet (3) for paste, suspension and/or liquid raw mixture. The part of the tower reactor that underlies hydrocyclone (2) is made of cascade (7) with downflow. Cascade (7) is connected with the bottom part of the tower reactor through the pipeline. The bottom part is made of one-step or multi-step zone (9) with falling film with zone (8) of preliminary pressure drop.
EFFECT: enhanced efficiency.
