Abstract
An apparatus comprises a reaction chamber provided with a charging hole, a branch pipe for discharging a suspension, and a branch pipe for withdrawing a vapor-gas phase which branch pipe is communicated with a condenser. The apparatus further includes a heater provided with a heat-exchanger for preheating a solvent, said heat-exchanger being introduced into said heater and communicated with said reaction chamber through nozzles adapted for jet feeding of the solvent into the reaction mass. At the outlet of the reaction chamber there is mounted a distillation column communicated with the branch pipe for discharging the suspension and provided in the upper portion thereof with a branch pipe for withdrawal of the vapor-gas phase, while in the lower portion thereof there is provided a branch pipe for discharging a distillation residue.
