CAS No 108-10-1 Methyl Isobutyl Ketone (MIBK) is an organic compound that belongs to the ketones and is an important solvent for the chemical industry. The substance is produced from acetone in a three-step process of aldol condensation, dehydration and hydrogenation via the intermediates diacetone alcohol and mesityl oxide. Natural methyl isobutyl ketone is found in small amounts in numerous plant and animal products.

What is the chemical use of MIBK solvent?
Coatings and Thinners: MIBK solvent is a primary solvent in the formulation of high-solids coatings, nitrocellulose lacquers, vinyl resin coatings, and thinners. Its medium evaporation rate ensures excellent flow, leveling, and blush prevention in the drying film.
Chemical Extraction Agent: MIBK (methyl isobutyl ketone) is widely used as an effective liquid-liquid extraction solvent, particularly in the pharmaceutical industry for purifying drugs and in the chemical industry for extracting high-value compounds like specific organic acids and inorganic salts (e.g., uranium extraction).
Adhesives and Sealants: Due to its strong solvency for acrylics and resins, it is incorporated into various adhesives, printing inks, and protective coatings to control viscosity and application properties.
Solvent for Synthesis: CAS 108-10-1 Methyl isobutyl ketone serves as a reaction solvent in various chemical synthesis processes, including the manufacture of isobutyl ketone peroxide, which is a common catalyst/initiator.
Cleaning and Degreasing: Used as a heavy-duty industrial cleaner and degreaser for specific resins, oils, and equipment where lesser solvents are ineffective.
