What is Butyl acrylate CAS 141-32-2?

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. Among the existing continuous production processes, 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.

Application

Acrylic acid and its esters are widely used in industry. During use, acrylic acid esters are often polymerized into polymers or copolymers. Butyl acrylate (as well as methyl acrylate, ethyl acrylate, 2-ethylhexyl acrylate) is a soft monomer, which can be copolymerized, cross-linked, grafted, etc. with various hard monomers such as methyl methacrylate, styrene, acrylonitrile, vinyl acetate, etc., and functional monomers such as (meth) hydroxyethyl acrylate, hydroxypropyl acrylate, glycidyl ester, (meth) acrylamide and its derivatives to make more than 200-700 kinds of acrylic resin products (mainly emulsion type, solvent type and water-soluble type), which are widely used in coatings, adhesives, acrylic fiber modification, plastic modification, fiber and fabric processing, paper treatment agents, leather processing, acrylic rubber and many other aspects.
