Butyl acrylate serves as a key monomer for manufacturing polymers used in fibers, rubbers, and plastics. In the organic chemical sector, it is applied to produce adhesives, emulsifiers, and organic synthesis intermediates. For papermaking, it acts as a paper reinforcing agent. In coatings, it is a core raw material for acrylic coatings. As one of the most significant acrylate esters, butyl acrylate is primarily produced worldwide via direct esterification in continuous industrial processes. Acrylic acid and n-butanol undergo esterification in two sequential reactors using organic acid catalysts, with water removed during reaction to drive equilibrium toward butyl acrylate formation.
