Information @ a Glance

  • Aldehydes and ketones are characterized by the the carbonyl functional group (C=O).
  • The compounds occur widely in nature as intermediates in metabolism and biosynthesis.
  • They are also common as chemicals, as solvents, monomers, adhesives, agrichemicals and pharmaceuticals.
  • Reaction of an aldehyde or ketone with hydrazine and base yields an alkane.
  • Phosphoranes add to aldehydes and ketones to give alkenes (the Wittig reaction).
  • The main commercial route to MEK is the dehydrogenation of secondary butanol. Some companies employ sulphuric acid hydration of n-butene to make the secondary butanol.
  • MEK could also become available as a byproduct from a new phenol process being developed by Shell.
  • Olefins higher than 3-C were converted to ketones using aqueous chloropalladate ion as oxidant.
  • Formaldehyde is used in the manufacture of formaldehyde-based resins and plastics used in many industries, but mostly in the wood-products industry.
  • Formaldehyde is also used in a number of industries including agriculture, the building industry (to water- and grease-proof concrete and plaster), medicine-based industries (forensics, hospitals and pathology laboratories), embalming fluid in funeral homes and crematoria, film processing, textile treatments, leather tanning and a wide range of personal care and consumer products.
  • Methyl ethyl ketone is used to produce perfumes, antioxidants and catalyst intermediates.
  • MEK can also be used in rubber-based industrial cements and printing inks.
  • The strongest growth market for MEK is in adhesives, chemical intermediates and printing inks.
  • Global MIBC statistics are difficult to estimate, but overall, MIBC will experience positive growth in lube oil applications and as a flotation frother .
  • MIBK consumption for antiozonants is forecast to grow at an average annual rate of 4–4.5% in Asia and 1–1.5% in the United States and Western Europe.
  • Global MIBK consumption will average growth of 2.5% per year from 2005 to 2010.
