Information @ a Glance

  • Hydroformylation, also known as oxo synthesis or oxo process, is an important industrial process for the production of aldehydes fromalkenes.
  • The overall mechanism resembles that for homogeneous hydrogenation with additional steps. The reaction begins with the generation of coordinatively unsaturated metal hydrido carbonyl complex such as HCo(CO)3 and HRh(CO)(PPh3)2. Such species bind alkenes, and the resulting
    complex undergoes amigratory insertion reaction to form an alkyl complex.
  • Hydroformylation is the simultaneous addition of one mole each of hydrogen and carbon monoxide across a carbon–carbon double bond of alkene to produce linear and branched aldehydes having one more carbon atom than the original compound.
  • OXO means process by adding synthesis gas to an olefin to obtain an aldehyde using the ydroformylation reaction and then hydrogenating the aldehyde to obtain the alcohol.
  • Key oxo alcohols sold in commerce include t n-Butanol, 2-Ethylhexanol, Isononyl alcohol, and Isodecyl alcohol.
  • n-Butanol is produced industrially from the petrochemical feedstock propylene. Propylene is hydroformylated to butyraldehyde (oxo process) in the presence of a rhodium-based homogeneous catalyst. The butyraldehyde is then hydrogenated to produce n-butanol.
  • The quantity demanded of n-butyl alcohol in China in 2015 is predicted to be 1,100~1,150 kmt (SRI predicted value is 1,096kmt, generally consistent). Compared with the production capacity of 1,185kmt/yr then, the supply and demand are basically balanced.
  • Oxea is a global manufacturer of Oxo Intermediates and Derivatives such as alcohols, polyols, carboxylic acids, specialty esters and amines.
  • Oxo industry growth continues to be strong, consistent with the broader global chemical industry development.
