Description générale

4-Methyl-2-pentanone (Methyl isobutyl ketone (MIBK)) is an organic solvent widely used in various industrial applications. It is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose. It is also used as a denaturant and solvent in cosmetic products.

Application

4-Methyl-2-pentanone is used:
  • To prepare (R)-(-)-4-methyl-2-pentanol via asymmetric hydrogenation in the presence of silica-supported starch-polysulfosiloxane-platinum complex (SiO2-ST-Si-S-Pt).
  • In the preparation of jet-fuel-range alkene [C10 and C11 branched alkanes] via aldol condensation reaction with furfural followed by hydrodeoxygenation reaction.
  • Extracting agent for silver, gold and other rare elements from cyanide solutions.
