Information On Methyl Isobutyl Ketone From Wikipedia

Methyl isobutyl ketone (MIBK) is the organic compound with the formula (CH3)2CHCH2C(O)CH3. This colourless liquid, a ketone, is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose. MIBK is used as a solvent for nitrocellulose, lacquers, and certain polymers and resins.  Read more here.

Precursor to 6PPD 

Another major use is as a precursor to N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylene diamine (6PPD), an antiozonant used in tires. 6PPD is prepared by reductive coupling of MIBK with 4-aminodiphenylamine.

Solvent And Niche Applications 

Unlike the other common ketone solvents, acetone and MEK, MIBK has quite low solubility in water, making it useful for liquid-liquid extraction. It has a similar polarity to ethyl acetate, but greater stability towards aqueous acid and base. It can be used to extract gold, silver and other precious metals from cyanide solutions, such as those found at gold mines, to determine the levels of those dissolved metals. Diisobutyl ketone (DIBK), a related lipophilic ketone, is also used for this purpose. Methyl isobutyl ketone is also used as a denaturing agent for denatured alcohol. When mixed with water or isopropyl alcohol MIBK serves as a developer for PMMA electron beam lithography resist. MIBK is used as a solvent for CS in the preparation of the CS spray used currently by British police forces.

Methyl Isobutyl Ketone Chemical Properties And Reference Resources

Methyl Isobutyl Ketone Uses 

Methyl isobutyl ketone is an important commercial chemical. It is used as a solvent, in the manufacture of many chemicals, in many chemical processes, in paints, and in dry cleaning products. It is also used as a flavoring agent and in food-contact packaging products. EXPOSURE: Workers that use methyl isobutyl ketone may breathe in vapors or have direct skin contact. The general population may be exposed by breathing air, using consumer products such as house paint and eating foods containing methyl isobutyl ketone as a flavoring. If methyl isobutyl ketone is released to the environment, it will be broken down in air. It may be broken down by sunlight. It will move into air from moist soil and water surfaces. It is expected to move through soil. It will be broken down by microorganisms, and is not expected to build up in fish. Read more here.

Methyl Isobutyl Ketone Synthesis

The synthesis of methyl isobutyl ketone (MIBK) can be carried out by the condensation of acetone in the presence of hydrogen over a supported metal catalyst. Previous studies have shown that hydroxyapatite is an excellent catalyst for condensation reactions. Read more here.

What Is Methyl Isobutyl Ketone Used For?

MIBK is used as a chemical intermediate, a solvent for manufacturing paints, rubbers, pharmaceuticals, other chemicals, and industrial cleaners. It is used in the semiconductor industry. MIBK is very efficient at dissolving resins used in paints, inks, lacquers, and other types of surface coatings. Read more here.

Diisobutyl Ketone Eastman™

DIBK (Diisobutyl Ketone) is a slow evaporating, low density solvent that has good activity for many synthetic resins including nitrocellulose, rosin esters, phenolics, hydrocarbons, alkyds, polyesters, and acrylics. It is useful as a retarder solvent to improve flow and minimize humidity blushing. Read more here.

Methyl Isobutyl Carbinol (MIBC)

Methyl isobutyl carbinol (MIBC), an organic chemical compound, is a liquid derivative of acetone with a pungent alcohol odor. It has limited solubility in water, but is miscible with most organic solvents. The main uses of MIBC are as a frother in mineral flotation and in the production of lubricant oil additives.
