IMPROVED METHOD OF CHEMICAL REACTION IN DILUTED WITH STEP OF MEMBRANE SEPARATION Russian patent published in 2016 - IPC B01D61/02 B01D61/12 

FIELD: chemistry.

SUBSTANCE: method of chemical reaction of the substrate in the diluted reaction mixture containing solvent, where the reaction is selected from a reaction circuit cycle, a polymerisation reaction, enzymatic reaction, which exhibits inhibition of enzymatic reaction substrate, exhibiting inhibiting product of reaction, which exhibits deposition the substrate or reagent, and their combinations, where the method involves the following steps: a) feeding the dissolved mixture of substrate and a solvent in the reactor inlet, b) inducing interaction reaction medium in the reactor, c) discharge from the outlet hole of the reactor reaction mixture containing reaction product, solvent and unreacted substrate, d) conducting a reaction mixture at first filtration membrane with side retentate and permeate side, where the first filtration membrane is permeable for solvent, provides impermeability for substrate and has clipping substrate 80-100 %, e) returning retentate containing unreacted substrate, on the side of the first membrane filtration retentate in reactor, at the stage (a) said substrate and solvent mixture is fed into said inlet opening of said reactor of feed system with dilution of the substrate, dilution of substrate supply tank substrate; the method further includes a step of return solvent, passed through the first filtration membrane permeate side of the first membrane system to feed with dilution of the substrate for dilution of the substrate.

EFFECT: improved method of chemical reaction.
