As organic solvent; in the surface coating industry; manufacture of smokeless powder; colorless synthetic resins.
Areas of application are production of paints, lacquers, varnishes, paint thinners and removers, adhesives, cements, sealants, magnetic tapes, artificial leather, transparent paper, printing inks, cleaner for electronic equipment, cosmetics, pharmaceuticals; degreasing of metal surfaces; extraction of fats, oils, waxes, natural resins; dewaxing of mineral oils or lube oils. Additionally, it is used as synthetic flavoring agent in foods and pharmaceuticals and as a sterilizer for bacterial spores on surgical instruments, hypodermic needles and syringes, and dental instruments; manufacturing of smokeless powder.
In contrast to its uses as a solvent, use as a chemical feedstock is of minor importance despite the great number of possible reactions; however, condensation with formaldehyde to obtain methyl isopropenyl ketone, autocondensation to form ethyl amyl ketone, and mixed condensation with acetone to obtain methyl amyl ketone are of interest. MEK is used to produce perfumes, antioxidants, catalysts, peroxides, and diacetal. ... The perfume industry reacts MEK with citral to obtain perfume components such as methylpseudoionone. Since 1962 MEK is permitted as an alcohol denaturant in the Federal Republic of Germany (by decree of Bundesmonopolverwaltung in Offenbach).
Solvent in nitrocellulose coatings and vinyl films, "Glyptal" resins, paint removers, cements and adhesives, organic synthesis, manufacture of smokeless powder, cleaning fluids, printing, catalyst carrier, acrylic coatings.
