ethyl ketone (MEK) is a colorless liquid with a sharp, sweet odor.
Methyl ethyl ketone (also known as 2-butanone) is a man-made chemical
that is also found in nature.
ethyl ketone is a flammable liquid. It is partially soluble in water,
and soluble in most other organic solvents. It will float on water while
it rapidly dissolves in it.
nature, MEK is made by some trees. It is also found in small amounts in
some fruits and vegetables. Manmade MEK is released into the air from
car and truck exhausts.
Process and Technology
main commercial route to MEK is the dehydrogenation of secondary
can also be made as a by-product in butane-based acetic acid
Ethyl Ketone (MEK) worldwide is, primarily, produced with n
butene/2-butene as the raw material via sec butyl Alcohol (SBA) route as
90-95% of SBA produced is utilized for manufacture of MEK.
modern MEK manufacturing unit shall comprise of the following key
sections :- Hydration of n-butenes to produce Sec Butyl Alcohol.,
Catalytic Dehydrogenation of SBA to produce Methyl Ethyl Ketone.
newer technology involves the direct oxidation of n-butene in solution
using palladium and cupric chlorides as catalysts.
ethyl ketone is used as a solvent for lacquers, adhesives; for cleaning
materials to be electroplated; for degreasing; in rubber and rubber
cement, printing inks, paints, wood stains, varnishes and paint removers
and in cleaning solutions; as a catalyst; and as a carrier.
used in shoe factories, printing plants and plastics factories. It is
also used in making sporting goods.
applications include solvent extraction in several industrial sector ,
the production of synthetic leather and transparent paper and use as a
favored for applications in coatings that utilize highly polar resins
such as epoxies, urethanes, cellulosics and vinyls.
functions as a dewaxing agent during the refining of lubricating oils.
use of MEK in adhesives, chemical intermediates and printing inks
represents strongest segments of growth all growing at rates
between 2 and 3 percent annually.
consumption to grow at an average rate of 3.5%/year during the 2005 –
2010 period to reach 1.3m tonnes in 2010.
strongest growth market for MEK is in adhesives, chemical intermediates
and printing inks.
projected that MEK demand will grow at an average rate of 6-7%/year to
reach about 300,000-320,000 tonnes/year
