Butyl Acrylate Monomer

Butyl acrylate is an organic compound with the formula C4H9O2CCH=CH2. A colorless liquid, it is the butyl ester of acrylic acid. It is used commercially on a large scale as a precursor to poly(butyl acrylate). Especially as copolymers, such materials are used in paints, sealants, coatings, adhesives, fuel, textiles, plastics, and caulk.

Butyl acrylate can be produced by the acid-catalyzed esterification of acrylic acid with butanol. Since it polymerizes easily, commercial preparations may contain a polymerization inhibitor such as hydroquinone, phenothiazine, or hydroquinone ethyl ether.
