Butyl acrylate, also known as n-butyl acrylate, has the mf C7H12O2 and mw 128.17. It is a colorless, transparent liquid with a mildly pungent odor and serves as one of the core monomers for synthesizing polymeric materials. Possessing an unsaturated double bond, it readily undergoes polymerization reactions and requires storage with polymerization inhibitors. It can copolymerize with other monomers (such as styrene and vinyl acetate) and polymerizes rapidly upon exposure to heat, light, or initiators. Industrially, it is primarily produced through the esterification reaction of acrylic acid with n-butanol, typically achieving a purity exceeding 99%.
