FIELD: chemistry.
SUBSTANCE: proposed aqueous solution of acrylamide is obtained through hydration of acrylonitrile in an aqueous solution in the presence of a biocatalyst. To carry out the reaction, a device is used, comprising a reactor and a centrifuge attached to it. To separate the biocatalyst from the aqueous solution of acrylamide, the centrifuge operates in a semi-continuous mode, at least. The centrifuge has optical means of controlling parameters of the clarified liquid medium tapped from it. The control results are used for controlling operation of the centrifuge. The method has the highest possible environmental friendliness and allows for minimising quantity of by-products.
EFFECT: design of an efficient method of making an aqueous solution of acrylamide.
