Process for producing acrylamide

Acrylamide (AM) is the production of polyacrylamide (PAM) is the main raw material, acrylamide directly affect the quality of the quality and effect of the synthesis of PAM, at present, the industrial production of acrylamide mainly by chemical method and biochemical method two.

The chemical method is to use the framework of copper as catalyst system, using the direct hydration method to produce acrylamide. Production of acrylamide is the second generation of synthetic technology. Using the technology of production of acrylamide acrylonitrile high conversion rate, good product quality, no by-products, low energy consumption, less waste discharge.

The biological enzyme is used as catalyst, and the propylene is fine, the water and the biological catalyst are blended into a hydration solution, and the catalyst can be obtained by separating the catalyst after the catalytic reaction. Compared with chemical method, acrylonitrile conversion rate higher, reaching 99.99%, no adverse reaction, no ion exchange separation and purification, more simple operation, without concentrated operation, operation more simple process, less equipment investment, high production efficiency, especially suitable for the production of high viscosity of polyacrylamide with ultrahigh molecular weight.
