Information @ a Glance

General

  • Alkyl acrylates are clear, volatile liquid; slightly soluble in water and complete soluble in alcohols, ethers and almost organic solvents.
  • Acrylate esters containing a double bond and functional carboxyl group are used chiefly as a monomer or co-monomer in making acrylic and modacrylic fibres.
  • Butyl acrylate is a clear, flammable liquid with a fruity, pungent odor.
  • Butyl acrylate is used in the preparation of polymers and copolymers with acrylic acid and its derivatives, methyl acrylate, vinyl chloride, butadiene, styrene
  • Butyl acrylate is a skin, ocular, and respiratory tract irritant in animals. It can cause skin sensitization.

Process

  • Butyl acrylate is made from ester grade acrylic acid and a small excess of butanol in a reactor bed at elevated temperature extracted at a yield of about 94-97%. It is usually integrated to an acrylic acid facility
  • Emulsion graft polymerization of styrene and acrylonitrile onto the copolymer of butyl acrylate was initiated by peroxy bonds in the D120 units of the backbone chains at 120°C.
  • The processes to prepare graft copolymers has been investigated intensively including radical graft copolymerization, which can be performed by using special initiators, chain transfer reaction, radiation polymerization, light polymerization, and mechanics.
  • Poly(butyl acrylate-co-styrene)–silver nanocomposites were prepared by g-irradiation of microemulsions and metallic silver nanoparticles of near uniform size were found to be well dispersed in the polymer matrix.
  • Living polymerization is considered to offer the best techniques for the preparation of polymers with controlled molecular weights and polydispersities. These processes enable chemists to synthesize polymers with predictable molecular weights and block copolymers with high blocking efficiency.

Technology

  • N-vinyl-2-pyrrolidone/butyl acrylate (V/B) copolymers have important applications in the photography, lithography, adhesive and pharmaceutical industries.
  • It has been pointed out that the copolymerization reactions provide an excellent way for the preparation of macromolecules with the specific chemical structures and for the control of properties such as solubility, polarity and hydrophilic/hydrophobic balances.
  • High resolution NMR spectroscopy has proven to be one of the most efficient and reliable technique for the determination of microstructure of N-vinyl-2-pyrrolidone/butyl acrylate copolymers.
  • The copolymerisation of styrene and butyl-acrylate monomer was carried out using conventional emulsion polymerisation.

Applications

  • Copolymers have acquired prime importance in various avenues of application in leather, textile and building materials.
  • It is used in formulating paints and dispersions for paints, inks, and adhesives.
  • It is used in making cleaning products, antioxidant agents, amphoteric surfactants. It is used in making aqueous resins and dispersions for textiles and papers.
  • Butyl acrylate is also a very useful feedstock for chemical syntheses, because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.

Market and Report
 

  • A number of factors drive demand for acrylates. Typically, acrylate trends align with the economy; as the economy improves, so does demand for acrylate products.
  • The acrylates market is expected to grow at or above 4 percent per year.
  • The US is the largest consumer at about 429,970 tonnes/year, followed by Western Europe at 412,630, Asia-Pacific at 365,960 tonnes/year.
  • 5%/year in Africa, 6%/year in Asia and the Middle East, 4%/year in Australia, New Zealand and eastern Europe, 3%/year in Americas and western Europe, and 1%/year in Japan.
  • Styrene (St) and butyl-acrylate (BA) monomers of a pure reagent grade were obtained from a reputed company in USA and used directly without further purification.
