METHOD FOR PREPARING ACRYLAMIDE AQUEOUS SOLUTION USING CATALYST Russian patent published in 2006 - IPC C12P13/02 C12M1/02 

Abstract RU 2289626 C2

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to synthesis of organic compounds. Acrylonitrile is hydrated in aqueous solution in the presence of a biocatalyst. Control for carrying out the reaction is carried out by measurements of parameters of the technological process in "on-line" regimen by infrared spectroscopy method with Fourier-transformation. The reaction is carried out in reactor fitted by circulation contour wherein part of the reaction mixture is pumped in closed cycle. Device comprises infrared spectrometer with Fourier-transformation providing carrying out measurements in "on-line" regimen rapidly and to retain activity of biocatalyst at the practically constant level in the reaction course and to produce larger amount of the more pure product.

EFFECT: improved method of synthesis.
