Acrylamide contains carbon-carbon double bond and amide group, which has the chemical commonality of double bond: it is easy to polymerize under ultraviolet irradiation or at melting point temperature;In addition, double bonds can be added to hydroxyl compounds under alkaline conditions to generate ethers. When added with primary amine, unary or binary admixture can be generated. When added with secondary amine, only unary admixture can be generated. When added with tertiary amine, quaternary ammonium salt can be generated. With the addition of activated ketone, the admixture can be immediately cyclized to form lactam.It can also be added with sodium sulfite, sodium bisulfite, hydrogen chloride, hydrogen bromide and other inorganic compounds; This product can also be copolymerized, such as with other acrylates, styrene, vinyl halide copolymerization; The double bond can also be reduced by borohydride, nickel boride, carbonyl rhodium and other catalysts to produce propionamide. Diol can be produced by catalytic oxidation with osmium tetroxide.The amide group of this product has the chemical commonness of aliphatic amide: react with sulfuric acid to form salt; In the presence of alkaline catalyst, acrylic ions were hydrolyzed to form. In the presence of acid catalyst, acrylic acid was hydrolyzed. In the presence of dehydrating agent, acrylonitrile is dehydrated. It reacts with formaldehyde to form N-hydroxymethylacrylamide.
Acrylamide is one of the most important and simplest acrylamide systems. It is widely used as raw materials for organic synthesis and polymer materials.The polymer is soluble in water, so it is used to produce flocculant in water treatment, especially for the flocculation of protein, starch in water has a good effect. In addition to flocculation, there are thickening, shear resistance, resistance, dispersion and other excellent properties.When used as a soil conditioner, it can increase the water permeability and moisture retention of soil;Used as paper filler supplement, can increase the strength of paper, in place of starch, water soluble ammonia resin; Used as chemical grouting agent, used in civil engineering tunnel excavation, oil well drilling, mine and dam engineering plugging;Used as fiber modifier, can improve the physical properties of synthetic fiber; Used as a preservative, can be used for underground components anticorrosion; Can also be used in food industry additives, pigment dispersant, printing and dyeing paste.With phenolic resin solution, can be made into glass fiber adhesive, and rubber together can be made into pressure sensitive adhesive.Many synthetic materials can be prepared by polymerization with vinyl acetate, styrene, vinyl chloride, acrylonitrile and other monomers. This product can also be used as medicine, pesticide, dye, paint raw materials.
