Acrylamide;Propenamide;Acrylicamide;2-Propeneamide
Molecular formula : C3H5NO
MW : 71.080
CAS No. :79-06-1

nature : odorless and colorless crystalline, toxic. 84-86 ° C melting point, boiling point of 87 ° C (cornea), 125 ° C (3.33kPa), 103 ° C (0.67kPa), the relative density of 1.122 (20 / 4 ° C), the refractive index of 1.460 (calculated values ). Dissolved in water, ethanol, acetone, ether and methyl chloroform and toluene-soluble, non-soluble in benzene. At room temperature stability, but when it is suddenly melt polymerization in aqueous solution increases hydroquinone, catechol tert-butyl -, phenyl-2-naphthylamine or other antioxidants can be made stable.

Preparation : 1. Acrylonitrile water sulfate and water legitimate acrylonitrile in the presence of sulfuric acid hydrolysis into acrylamide sulfate, and then use liquid ammonia and the formation of acrylamide and ammonium sulfate solution, the reaction after separation by filtration, liquid crystal, dry derived products. The shortcomings of this method is substantial value by-product ammonium sulfate low, serious corrosion and sulfate pollution. Acrylamide ton-product ammonium sulfate 2280kg. The consumption of raw materials fixed : acrylonitrile (100%) 980kg / t, sulfuric acid (100%) 200kg / t, ammonia (100%) 3891 / t. 2. Acrylonitrile acrylonitrile legitimate direct water and water in the presence of copper catalysts, 85-125 ° C and 0.3 - 0.4 MPa pressure generated from direct hydration. The law of acrylamide aqueous solution (containing only a small amount of by-products), as a direct product sales, acrylamide avoid dust pollution, water use on labor protection is beneficial. Reference product specifications : appearance of a white powder or Flake. Commodities in a ?95%; Two goods in ?90%; Three goods content ?85%. 3. Enzyme catalysis at room temperature to acrylonitrile into aqueous solution containing the bacteria catalyst bed reactor, the reaction by 100% acrylonitrile into acrylamide. After separation, or even bypass refining, to be concentrated on acrylamide industrial products.

purposes : Acrylamide is acrylamide-and methyl acrylamide is the most important product of the products. Since 1954 for the industry, the need to gradually increase. Mainly used for extracting water soluble polymers, which can be used as polyacrylamide additives used to enhance oil recovery; For flocculants, thickening agent and paper additives. A small amount of acrylamide was to be used for the introduction of hydrophilic center of the oil-polymer to improve viscosity, softening point increase resin and solvent resistance, and for the dye by the introduction of a color nature center. Acrylamide is also often used as a photosensitive polymer components. The vinyl polymer, in the crosslinking reaction can use this acylamino of the reaction. Can acrylamide monomer with some, such as vinyl acetate, styrene, vinyl chloride, ethylene fork dichloro, acrylonitrile copolymer, such as access to a variety of uses of polymer. The main application areas : (a) The goods oilfield injection wells for water injection profile adjustment. Will the goods and initiator, Deaerator agent mixed into water injection wells with high permeability layer. The formation of polymerization into high viscosity polymer. Plugging holes, increasing swept volume, increased production rate. In addition, the polymer materials or copolymers can be used to EOR, fracturing, water shutoff, drilling, processing and mixing chemical grouting, and so on. (2) Flocculant for the goods on or partially hydrolyzed with methyl cellulose graft copolymer for the wastewater treatment plant and under water. (3) the use of soil improvers on the hydrolysis products for soil conditioner, soil aggregates and improve air circulation, water permeability and retention. (4) fiber and resin modified processing of acrylamide for CARBAMOYLTRANSFERASE or polymerization. Can be used to improve the content of synthetic resin fibers, yarn and dyeing slurry for use to improve the fabric on the basis of sex, fabric antifelting and feel good. (5) permits power intensifier acrylamide copolymer of acrylic acid and polyacrylamide or part hydrolyzate and can be used as paper Li-pei - agent, has replaced the use of starch, water-soluble amino resin or shared. (6) polyacrylamide adhesive with a phenolic resin solution and the use of glass fiber adhesives, synthetic rubber and with the use of pressure sensitive adhesive.
