Butyl acrylate is mainly used to make polymer monomers for fibers, rubbers, and plastics. It is used in the organic industry to make adhesives, emulsifiers, and as an organic synthesis intermediate. It is used in the papermaking industry to make paper reinforcing agents. It is used in the coating industry to make acrylic coatings. Butyl acrylate (butyl acrylate) is the most important variety of acrylic esters. In the existing continuous Chemicalbook production process, direct esterification of butyl acrylate is the main production method in the world at this stage. Its main process flow is: the raw materials acrylic acid and n-butanol are esterified in two series reactors, organic acids are used as catalysts, and the method of dehydration while reacting is adopted to make the reversible esterification equilibrium reaction proceed as far as possible in the direction of butyl ester formation.
