Chemical Description

  • Used as pharmaceutical and dye intermediates.
  • The pesticide mite dead net produced by O-chlorobenzaldehyde can prevent and control mites on drought crops and fruit trees.
  • O-chlorobenzaldehyde oxime can be obtained by oximation of o-chlorobenzaldehyde, and further chlorination can be obtained by o-chlorobenzaldehyde, which are drug intermediates.
  • Methyl isobutyl ketone also known as MIBK,the chemical formula is C6H12O, an organic chemical compound.Colorless transparent liquid, easy to burn, volatile.
  • Mainly used for spray paint, nitro fiber, some fiber ethers, camphor, oil, natural and synthetic rubber solvents.
  • A clear colorless liquid with a pleasant odor. Flash point 73°F. Less dense than water. Vapors heavier than air.
  • Flammable, dangerous fire risk, explosive limits in air 1.4–7.5%. Avoid ingestion and inhala-tion. Upper respiratory tract irritant, dizziness, and headache. Possible carcinogen.
  • Vapor causes irritation of eyes and nose; high concentrations cause anesthesia and depression. Liquid dries out skin and may cause dermatitis; irritates eyes but does not injure them.
  • 4-Methyl-2-pentanone has a pleasant odor. May be prepared by hydrogenation of mesityl oxide over Ni at 160 - 190°C; also by oxidation of methyl isobutyl carbinol.
  • Methyl isobutyl ketone is a colorless liquid with a pleasant, sweet, fruity odor. The odor threshold can be as low as 0.10 ppm. It is 2% soluble in water by weight and with several other organic solvents.
  • The lower explosive limit is 1.2% and the upper explosive limit is 8.0% at 200 °F. Methyl isobutyl ketone may be incompatible with strong oxidizers and potassium tert-butoxide.
  • Methyl isobutyl ketone (hexone, isobutyl methyl ketone, 4-methyl-2-pentanone) is an organic solvent similar in structure and use to methyl butyl ketone.
  • In addition to its use as a solvent for paints, lacquers, and varnishes, methyl isobutyl ketone is used in extraction processes and as a denaturant for rubbing alcohol.
  • Methyl isobutyl ketone is also used as a synthetic flavoring in some varieties of rum, candy, and cheese. Unlike methyl butyl ketone, methyl isobutyl ketone has not been found to occur naturally.
