Acrylic acid is the simplest unsaturated carboxylic acid, with a molecular structure consisting of a vinyl group and a carboxyl group. Pure acrylic acid is a colorless, clear liquid with a characteristic pungent odor. Its density is 1.0511. Its melting point is 14°C. Its boiling point is 140.9°C. It is highly acidic and corrosive. It is soluble in water, ethanol, and ether. Its chemical properties are active. It readily polymerizes to form a transparent white powder. Reduction produces propionic acid. Addition of hydrochloric acid produces 2-chloropropionic acid, which is used in the preparation of acrylic resins and other organic syntheses. It can be obtained by the oxidation of acrolein or the hydrolysis of acrylonitrile. It can also be synthesized from acetylene, carbon monoxide, and water, or by the pressurized oxidation of ethylene and carbon monoxide.

Acrylic acid and its series of products are widely used in coatings, plastics, textiles, leather, papermaking, building materials, packaging materials and many other sectors. Acrylic acid and its esters can be used for organic synthesis and polymer synthesis, and the vast majority are used in the latter, and more often they are copolymerized with other monomers such as vinyl acetate, styrene, methyl methacrylate, etc. to produce synthetic resins with various properties, functional polymer materials and various additives. Main application areas: Warp yarn sizing agent made from raw materials such as acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, and ammonium polyacrylate. Chemicalbook desizing capacity is higher than polyvinyl alcohol sizing agent, saving starch, etc.
