Mobile, liquid; distills between 114 & 117 deg C /NF Grade/
Bulk density: 6.68 lb/gal at 20 deg C
Liquid water interfacial tension: 15.7 dynes/cm = 0.0157 N/m at 22.7 deg C. Vapors heavier than air
Water/air, blood/air, oil (olive oil)/air, oil/water, and oil/blood partition (or solubility) coefficients of methyl isobutyl ketone were measured by vial-equilibration in combination with gas chromatography. Partition coefficients for methyl isobutyl ketone: water/air: 79; blood/air: 90; oil/air: 926. The blood/air partition coefficients for ketones are almost in the same range as the water/air, irrespective of the oil/air partition coefficients.
Henry's Law constant = 1.38X10-4 atm-cu m/mol at 25 deg C (est)
Hydroxyl radical reaction rate constant = 1.30X10-11 cu cm/molec-sec at 25 deg C (est)
