Water Treatment Chemical Supply Chain Profile - Acrylamide
There are multiple commercial methods available to produce acrylamide. All methods utilize acrylonitrile as the starting material. Domestic production takes place primarily through one of two methods. In the first method, acrylamide is produced by the hydrolysis of acrylonitrile with the bacterial enzyme nitrile hydratase.

Where is acrylamide produced?
SNF Holding, which claimed CBI, indicated status as a leading worldwide producer of polyacrylamide, supplying 48% of worldwide consumption in 2020 (SNF, 2021). Reported domestic production of acrylamide takes place at six facilities located in Georgia, Louisiana, Mississippi, and Virginia.
Is acrylamide used in water treatment?
Domestic production relies on supply of acrylonitrile, a petroleum-derived compound. None. Acrylamide is not used directly in water treatment. Acrylamide is the primary input for production of polyacrylamides, which are used in water treatment as coagulants and dewatering agents. Water treatment is a primary use of polyacrylamides.
What enzyme converts acrylonitrile into acrylamide?
Bacteria which utilize acrylonitrile among other nitriles as the sole source of carbon and nitrogen produce an enzyme called nitrile hydratase which converts acrylonitrile into acrylamide. Nitrile hydratase is harvested from bacterial cultures and used in the industrial production of acrylamide (Asano et al., 1982).
What is acrylamide used for?
Acrylamide is an intermediate in the production of many organic chemicals. Most uses rely on production of polyacrylamide. Common applications include use in enhanced oil recovery, pulp and paper processing, mineral processing, production of dyes and adhesives, cosmetics, and laboratory research (electrophoresis) (ATSDR, 2012; NCBI, 2022).
