Acrylamide (CAS No. 79-06-1) is a colorless transparent flake crystal, odorless and toxic. Its relative density is 1.122, and its melting point is 84-85°C. Soluble in water and ethanol, slightly soluble in benzene and toluene. Very easy to sublimate and easy to aggregate. The solid is stable at room temperature and can polymerize violently when melted. By acrylonitrile with sulfuric acid or with metal catalyst hydrolysis in the system. Its polymer or copolymer is used as a chemical grouting material; it can be used as a photosensitive resin board in the printing industry; it can be used as a tackifier in the petroleum industry; it can be used as a sizing agent in the glass fiber industry; it can also be used as a soil conditioner and flocculant , Fiber modifiers and coatings, etc.
This product is the most important and simplest in the acrylamide series. It has a wide range of uses and is used as a raw material for organic synthesis and a raw material for polymer materials. The polymer is soluble in water, so it is used to produce flocculant in water treatment, especially for the flocculation of protein and starch in water. In addition to flocculation, it also has excellent properties such as thickening, shear resistance, resistance reduction, and dispersibility.
When used as a soil amendment, it can increase the water permeability and moisture retention of the soil; used as a paper filler adjuvant, can increase the strength of the paper, instead of starch, water-soluble ammonia resin; used as a chemical grouting agent, used in civil engineering It can be used as a fiber modifier to improve the physical properties of synthetic fibers; it can be used as a preservative and can be used for anticorrosion of underground components; it can also be used as additives and pigments in the food industry. Dispersant, printing and dyeing paste. When combined with phenolic resin solution, it can be made into glass fiber adhesive, and together with rubber, it can be made into pressure-sensitive adhesive, etc. It can be polymerized with vinyl acetate, styrene, vinyl chloride, acrylonitrile and other monomers to prepare many synthetic materials. This product can also be used as a raw material for medicines, pesticides, dyes, and coatings.
