1.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, clarified liquid with a characteristic irritating odor. Density 1.0511. Melting point 14°C. Boiling point 140.9°C. Highly acidic. Corrosive. Soluble in water, ethanol and ether. Chemically active Chemicalbook. Easily polymerized into transparent white powder. Produces propionic acid when reduced. Produces 2-chloropropionic acid when added with hydrochloric acid. Used in the preparation of acrylic resins, etc. Also used in other organic synthesis. Produced by oxidation of acrolein or hydrolysis of acrylonitrile, also synthesized from acetylene, carbon monoxide and water, or produced by oxidation of ethylene and carbon monoxide under pressure.
2.Acrylic acid can undergo the characteristic reaction of carboxylic acids and the corresponding esters can be obtained by reaction with alcohols. The most common acrylic esters include methyl acrylate, butyl acrylate, ethyl acrylate, and 2-ethyl
3.Acrylic acid and its esters, by themselves or mixed with other monomers, undergo polymerization to form homopolymers or copolymers. Common monomers that can be copolymerized with acrylic acid include amides, Chemicalbook acrylonitrile, vinyl-containing, styrene and butadiene. These polymers are used to produce a variety of plastics, coatings, adhesives, elastomers, floor polishes and paints.
1.Main application areas: (1) warp sizing material prepared by acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate and other raw materials, Chemicalbook than polyvinyl alcohol sizing material capacity desizing, saving starch. (2) adhesive with acrylic acid, methyl acrylate, ethyl acrylate, acrylic acid-2-ethylhexyl and other copolymer latex, can be used for electrostatic flocking, flocking adhesive, its firmness and feel good. (3) water thickener with propionic acid and ethyl acrylate copolymer made of high molecular weight powder. Can be used as thickening agent, used in oil fields, each ton of product can increase production of 500t of crude oil, the effect of oil recovery on old wells is better. (4) coated paper finishing agent with acrylic acid, butyl acrylate, acrylic acid-2-ethylhexyl ester, styrene and other quaternary copolymer latex for coated paper coating, color retention without yellowing, good printing performance, not sticky rollers, better than styrene butyl latex can save dry coolin. (5) polyacrylic acid salts using acrylic acid can produce a variety of polyacrylic acid salts (such as ammonium salts, sodium salts, potassium salts, aluminum salts, nickel salts, etc.). Used as coagulant, water treatment agent, dispersant, thickener, food preservation agent acid and alkali resistant desiccant, softening agent and other kinds of polymer additives.
2.Preparation of polymers by homopolymerization or copolymerization for coatings, adhesives, solid resins, molding compounds, etc.
