有丙酮气味。易溶于乙醇和乙醚，极微溶于水。易燃。中等毒，半数致死量（大鼠，经口）148mg/kg。有刺激性。 溶剂。有机合成。塑料工业。 3-Methyl-2-butanone (Methyl isopropyl ketone, MIPK, isopropyl methyl ketone), an aliphatic ketone, is a volatile organic compound. Photodegradation of MIPK in gas-phase has been reported. Asymmetric hydrogenation of MIPK with high enantioselectivity in the presence of Rh-PennPhos (rhodium-P,P′-1,2-phenylenebis(endo-2,5-dialkyl-7-phosphabicyclo[2.2.1]heptane) complex has been reported. 3-Methyl-2-butanone may be used to prepare (R)-3-methyl-2-butanol via asymmetric hydrogenation in the presence of a wool-Pd complex.
