Butyl Acrylate CAS#141-32-2
Versatile Application: Used in the production of fibers, rubbers, plastics, adhesives, emulsifiers, and coatings.
Key Industrial Component: Essential in manufacturing paper reinforcing agents and as an intermediate in organic synthesis.
Stable and Flammable: Stable under normal conditions but highly flammable, making it easy to work with in controlled environments.
Light Sensitivity: Sensitive to light, ensuring it can be easily handled in specific conditions without degradation.
Butyl acrylate is primarily used in the production of polymer monomers for fibers, rubbers, and plastics. It serves as a key component in the organic industry for producing adhesives, emulsifiers, and as an intermediate in organic synthesis. In the paper industry, it is used to manufacture paper reinforcing agents, while in the coating industry, it is used for acrylic coatings.
As one of the most significant types of acrylic esters, butyl acrylate is primarily produced through direct esterification in continuous production processes. The process involves esterifying acrylic acid and n-butanol in two series reactors, with organic acids as catalysts, and employing a dehydration method to drive the reversible esterification equilibrium toward the formation of butyl ester.
