Methyl Isobutyl Ketone (MIBK)


Chemical Formula : C6H12O                  CAS Registry Number : 108-10-1


Methyl isobutyl ketone (MIBK) is the organic compound with the formula (CH3)2CHCH2C(O)CH3. This colourless liquid, a ketone, is widely used as a solvent.



Methyl isobutyl ketone is manufactured from acetone via a three-step process. Firstly acetone undergoes an aldol condensation diacetone alcohol, which readily dehydrates to give mesityl oxide. Mesityl oxide can then be hydrogenated to give MIBK:


Chemical Structure


MIBK is a natural choice in formulating nitrocellulose lacquers, acrylic, epoxy, polyurethane and vinyl resin coatings. MIBK may be used as a universal thinner for e.g. spray applications. As an extractant, this medium-boiling ketone finds use in the manufacture of antibiotics and in the dewaxing and deoiling of petroleum products. Other applications include its use as a component of synthetic rubber cements, adhesives, printing inks, as a carrier for crop protection formulations and as an ethyl alcohol denaturant. It is widely used in the manufacture of dry cleaning preparations, germicides, fungicides, textile coatings, leather finishes, electroplating solutions, pharmaceuticals, cosmetics and magnetic tapes.
