丙烯酰胺水合液 - Preparation Method
Open Data Verified Data
- acrylonitrile direct hydration acrylonitrile and water are directly hydrated in the presence of copper catalyst at 85~125 ℃ and 0.3~0. 4MPa pressure.
- acrylonitrile sulfuric acid hydration acrylonitrile and water are hydrolyzed in the presence of sulfuric acid to form acrylamide sulfate, and then neutralized with liquid ammonia to form acrylamide solution and ammonium sulfate. After the reactants were separated and filtered, the filtrate was crystallized and dried to obtain a final product.
- enzymatic method an aqueous acrylonitrile solution was fed into a fixed-bed reactor equipped with a bacterial strain catalyst at room temperature, and 100% of the acrylonitrile was converted to acrylamide by reaction. After separation, an industrial product of acrylamide can be obtained even without purification and concentration.

丙烯酰胺水合液 - Use
Open Data Verified Data
It is mainly used for the manufacture of water-soluble polymer-polyacrylamide, which can be used as a chemical grouting agent for water plugging and sand fixation in tunnels, oil wells, mines and dams, coagulants for water treatment and drilling mud and preservatives for underwater and underground structures. In addition, also
It can be used as soil modifier, fiber modifier, binder, photosensitive resin crosslinking agent and paper reinforcing agent. In addition, acrylamide can be used as a cross-linking agent for vinyl polymers and to increase the adhesion of lipophilic polymers, increase the softening point of the resin, and increase the solvent resistance.
