Products Description of 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. In the existing continuous 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.

Product Application of Butyl acrylate CAS#141-32-2

Butyl acrylate is a more active variety in the general-purpose acrylates. It is a highly reactive soft monomer that can crosslink, copolymerize and connect with a variety of hard monomers (hydroxyalkyl, glycidyl, methyl amide) to form a variety of polymers such as emulsions and water-soluble copolymers. It can also prepare plastic and crosslinked polymers to obtain a variety of products with different characteristics such as viscosity, hardness, durability, and glass transition temperature. Butyl acrylate is an important intermediate with high application consumption. It is widely used in coatings, textile adhesives, plastic synthetic fibers, detergents, highly absorbent materials, chemical additives (dispersion, flocculation, thickening, etc.), synthetic rubber and other industries. In particular, it has attracted much attention abroad as a modifier for MMA and MBS resins.
