Acrylic acid CAS#79-10-7

Acrylic acid is a carboxylic acid, of which the primary use is in the production of acrylic esters[2]. It has been traditionally used as the raw material for acrylic esters – methyl acrylate, ethyl acrylate, butyl acrylate and 2-ethylhexyl acrylate which were originally used to produce solvent-based acrylic resins but environmental concerns about solvent use led to the development of water-based acrylics[7]. Acrylic acid can readily react with a wide variety of organic and inorganic compounds which results in it’s considered as a very useful feedstock to manufacture many low molecular compounds, such as propionic acid, unsaturated fatty acids, heterocyclic compounds, and Diels-Alder addition products. As a vinyl compound and a carboxylic acid, acrylic acid is used widely for polymerisation, including production of polyacrylates. It is also a monomer for polyacrylic and polymethacrylic acids and other acrylic polymers[4].

Product Application Of Acrylic acid CAS#79-10-7

Acrylic acid (IUPAC: prop-2-enoic acid) is an organic compound with the formula CH2=CHCO2H. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform. More than one billion kilograms are produced annually.
