Uses and synthesis of Acrylamide powder

Acrylamide powder (AM for short) is usually colourless transparent flaky crystals, Acrylamide CAS 79-06-1 is a white crystalline solid, easily soluble in water, methanol, ethanol, propanol, slightly soluble in ethyl acetate, chloroform, slightly soluble in benzene, can be hydrolysed in acid and alkali environment to acrylic acid.

Acrylamide Raw Materials is the parent compound of a large class of monomers, including methacrylamide, AMPS, DMC and N-substituted acrylamide compounds.

Applications / Functions of Acrylamide powder

• Acrylamide CAS 79-06-1 Used as monomer of polyacrylamide, its polymers or copolymers are used as chemical grouting substances, soil conditioners, flocculants, adhesives and coatings.
• Polyacrylamide as an additive can improve the recovery of oil. It is used as a flocculant in wastewater treatment and as a paper reinforcing agent.
• Acrylamide powder is the raw material for the production of polyacrylamide and its series of products.
• Acrylamide Raw Materials are the most important products in the acrylamide and methacrylamide family.

Physicochemical Property of Acrylamide powder

Colourless and odourless crystal. Acrylamide powder is soluble in water, ethanol, acetone, ether and trichloroethane, slightly soluble in toluene, insoluble in benzene.

Production methodprocess of Acrylamide powder

1. Sulfuric acid aqueous method will be concentrated sulfuric acid, phenothiazine (polymerisation reaction inhibitor), water mixed and added to the reactor, slowly under stirring drops of acrylonitrile, drop after drop, heating to 95 ~ 100 ℃, holding 50min. cooling to 20 ~ 25 ℃, add the appropriate amount of water diluted with sodium carbonate and neutralised to neutral, filtration, to get acrylic acid aqueous solution. Then cooled and crystallised, separated and dried to get Acrylamide CAS 79-06-1 .
2. Catalytic hydration method acrylonitrile and water in the copper catalyst for liquid-phase hydration, generally used in continuous production, the reaction temperature of 85 ~ 120 ℃, reaction pressure of 0.29 ~ 0.39MPa, feed concentration of 6.5%, air speed of about 5L / h, conversion rate of 85%, selectivity of about 95%, the reaction generated Acrylamide powder concentration of 7% ~ 8%! The aqueous solution of acrylamide obtained by this method can be directly sold as a product.
