- Catechol, also known as pyrocatechol
or 1,2-dihydroxybenzene, is an organic compound with the molecular
- It is the ortho isomer of the three
- This colorless compound occurs
naturally in trace amounts. About 20 million kg are produced
annually, mainly as a precursor to pesticides, flavors, and
- 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
- 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
- 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
- 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
- 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.
