Project at a Glance Contents on the CD ROM
  • Catechol, also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C6H4(OH)2.
  • It is the ortho isomer of the three isomeric benzenediols.
  • This colorless compound occurs naturally in trace amounts. About 20 million kg are produced annually, mainly as a precursor to pesticides, flavors, and fragrances.
  • Catechol occurs as feathery white crystals that are very rapidly soluble in water.
  • Catechol is produced industrially by the hydroxylation of phenol using hydrogen peroxide.
  • Previously, catechol has been produced by hydrolysis of 2-substituted phenols, especially 2-chlorophenol, with hot aqueous solutions containing alkali metal hydroxides.
  • Its methyl ether derivative, guaiacol, converts to catechol via hydrolysis of
    the CH3-O bond as promoted by hydriodic acid.
  • Catechol is the conjugate acid of a chelating agent used widely in coordination
  • Small amounts of catechol occur naturally in fruits and vegetables, along with the
    enzyme polyphenol oxidase (also known as catecholase, or catechol oxidase).
  • Upon mixing the enzyme with the substrate and exposure to oxygen (as when a potato or
    apple is cut and left out), the colorless catechol oxidizes to reddish-brown melanoid pigments, derivatives of benzoquinone.
  • Catechol is used as a black-and-white photographic developer.
  • Pyrocatechol is a natural occuring plant poly phenol that is used as an ingredient for the production of insecticides, perfumes and drugs.
  •  It is further most used in dyestuffs, electroplating, antioxidants and light stabilizers and in organic synthesis.
  • It is also prepared by treating salicyladehyde with hydrogen peroxide or from its monomethyl ether(guaiacol) by treatment with hydrobromic acid.
  • It is one of the central intermediates in aerobic aromatic metabolism.
  • Process for the oxidation of phenol to a mixture of hydroquinone and catechol using hydrogen peroxide as oxidant in the presence of titanium silicate molecules in a multistage fixed bed reactor.
  • As phenolic antioxidants, it has been extensively used in chemical, food and pharmaceutical industry.
  • The extraction efficiency in the presence of magnesium salts in comparison to the extraction efficiencies from the salt-free aqueous solutions increased from 14% in the case of catechol extraction with diethylether.
