PAM main raw material acrylic production process

Acrylamide (AM) is the main raw material for the production of PAM (PAM). The quality of acrylamide directly affects the effect and quality of synthetic PAM. At present, the industrial production of acrylamide mainly uses chemical and biochemical methods.

The chemical method uses acrylonitrile as a raw material and uses framework copper as a catalyst system to produce acrylamide by direct hydration. It is the second generation synthesis technology for acrylamide production. The acrylamide acrylonitrile produced by this technology has high conversion rate, good product quality, no by-products, low energy consumption, and low emissions of three wastes.

The biochemical method uses a biological enzyme as a catalyst to formulate acrylonitrile, water and a biocatalyst into a hydration solution, and after the catalytic reaction, the catalyst is separated to obtain an acrylamide product. Compared with the chemical method, the conversion rate of acrylonitrile is higher, reaching 99.99%, no side reaction, no ion exchange, simple separation and refining operation, no need for enrichment operation, simpler operation process, less equipment investment, high production efficiency, especially Suitable for the production of high viscosity ultra high molecular weight polypropylene
