Uses and applications

What the substance is used for, by industry and function

Pure 2-ethylphenol ... is used as a starting material for photochemicals.

Industrial uses: Corrosion inhibitor, Cleaning agent, Fragrance, Surfactant (surface active agent), Solvent.

Consumer uses: Solvent, Fragrance, Cleaning agent.

Functional uses

  • Flavouring and nutrient
  • Fragrance

How it is made

Prepn: ...heating ethylene & phenol with phosphoric acid @ 200 °c, by heating ethanol & phenol over thoria + alumina @ 350 °c, from phenol, ethylene chlorohydrin & sodium.

2-Ethylphenol is produced industrially by ortho-alkylation of phenol with ethylene in high pressure autoclaves at 320-340 °C and 20 Mpa in the presence of 1-2% aluminum phenolate. If a molar ratio of phenol-ethylene of ca. 1:2 is used, the yield (related to converted phenol) is ca. 32% 2-ethylphenol ... after 6 hour reaction time.
