Chemical and physical properties: A colorless, stabile liquid with a sweetish-menthol smell, not soluble in water, dissolves well in most organic solvents, inflammable

Application of the substance: Diisobutyl ketone is widely used in industrial chemistry and industry. It ensures good solubility of numerous synthetic resins, among others vinyl, acryl, alkyd, polyester and epoxy resins. It can also be used as a solvent in nitrocellulose varnishes, coatings with a high contents of solid parts, and as a pain remover. It is also used as a solvent for adhesives, printing inks and in the cleaning and degreasing processes, as well as a component of dyes and insecticides. Diisobutyl ketone is also used in mining as aids in mining minerals and in extracting gold and rear earth metals from aqueous solutions, for instance for analytic purposes. It is also used as a solvent and aids in the extraction and recristallization process, and as a drug component in the pharmaceutical industry. DIBK is also an important component in the production of diisobutylcarbinol.

Health safety: Inhaling the vapors irritates the respiratory passages. It can also cause coughing, dizziness, stupor, nausea, vomiting and headache. A higher concentration can cause the depression of the central nervous system, coma and blackout. The odor of that substance is recognizable at a concentration considerably lower than that having harmful effects and should be a sufficient warning against overdosing.
