Summary
Acrylic acid is the simplest unsaturated carboxylic acid, with a molecular structure consisting of one vinyl group and one carboxyl group. Pure acrylic acid is a colorless clear liquid with a characteristic pungent odor. Density 1.0511. Melting point 14 ºC. Boiling point 140.9 ºC. Strong acidity. Corrosive. Dissolve in water, ethanol, and ether. The chemical properties are lively. Easy to aggregate into transparent white powder. Generate propionic acid during reduction. When added with hydrochloric acid, 2-chloropropionic acid is generated, which is used for the preparation of acrylic resins and other organic synthesis. It can be obtained by oxidation of acrolein or hydrolysis of acrylonitrile, or synthesized from acetylene, carbon monoxide, and water, or by pressure oxidation of ethylene and carbon monoxide.
Chemical Reaction
Acrylic acid can undergo characteristic reactions of carboxylic acids, and can also react with alcohols to obtain corresponding esters. The most common acrylic esters include methyl acrylate, butyl acrylate, ethyl acrylate, and 2-ethylhexyl acrylate. Acrylic acid and its esters, either on their own or when mixed with other monomers, undergo polymerization reactions to form homopolymers or copolymers. Monomers that can usually copolymerize with acrylic acid include amides, acrylonitrile, vinyl containing monomers, styrene, and butadiene. This type of polymer can be used to produce various plastics, coatings, adhesives, elastomers, floor polishes, and coatings.
Chemical Properties
Colorless liquid with a pungent odor. Can dissolve in water, ethanol, and ether.
Purpose
Preparation of high polymers through homopolymerization or copolymerization, used in coatings, adhesives, solid resins, molding compounds, etc
