Butyl Glycol

  • Ethylene glycol is a clear, colourless liquid with a syrupy consistency.
  • Ethylene glycol can be made industrially by reacting water with ethylene oxide
  • Ethylene glycol is used as an antifreeze, engine coolant and in the manufacture of polyester fibres and plasticisers
  • Butyl Glycol is also a starting material in the production of plasticisers by the reaction of phthalic anhydride.
  • Butyl glycol is produced by reacting ethylene oxide and normal butanol (n-butanol) using a catalyst. If the ratio of ethylene oxide to n-butanol is greater than one then di- and tri- ethylene glycol monoethers are also produced.
