2-ethylhexanol ( 2-EH short ) is a fully synthetic, branched primary alcohol having a characteristic odor. He has little meaning as a solvent. Most of it is chemically processed.

Production

The starting material for the production of propylene is ethylhexanol, the ethene produced in the steam cracking. The propene is reacted with carbon monoxide and hydrogen to butanal ( butyraldehyde ). This in turn is reacted with an aldol condensation to give 2-ethyl- 3-hydroxy- hexanal. After elimination of water and a catalytic hydrogenation, 2-ethylhexanol. Another approach is the reduction of 2- ethylhexanal.

Use

  • In some cases, 2-EH is used as the solvent for non-polar substances.
  • Ethylhexanol is esterified mainly with phthalic acid. The resulting phthalate DEHP used as a plasticizer in plastics.
  • Ethylhexanol is reacted with ethylene oxide and used as a nonionic surfactant.
  • Starting material for 2- ethylhexyl sulfate, which is used for example as a solubilizer.

Safety

When inhaled, cough, dizziness, headache, sore throat and fatigue may occur. Skin and eye irritation may occur.
