Methylethylketone (butanone) — - a chemical compound of a class of ketones, colourless easily flying liquid with the smell reminding an acetone smell - Possesses all chemical properties characteristic of aliphatic ketones, is used as solvent and raw materials in organic synthesis.
Methylethylketone (MEK) in laboratory is received dehydrogenation by two-butanola. To identify MEK, make the special product of seven-carbazones which is a methylethylketone derivative. Temperature of melting makes about 148 degrees. In the world production, more than a vosmist of thousands of tons of MEK is annually carried out. Dva-butenon it is necessary to store in rooms which have rather good system of ventilation allowing to carry out collecting, and also return of MEK vapors.
At concentration of MEK of 1 milligrams on liter within five minutes of impact on the person, substance causes notable irritation of mucous membranes of a throat, nose, an eye. At concentration of 300 milligrams on liter – influence is simply intolerable. Admissible concentration of methylethylketone is equal about 200 milligrams on cubic meter.
Apply C4H8O methylethylketone as:
- solvent of perkhlorvinilovy, nitrocellulose, polyacrylic paints and varnishes and glues, typographical paints, dewaxings of lubricant oils and deoiling of paraffin (removal of mix of oil and low-melting paraffin) -
- intermediate product in production of peroxide of methylethylketone (a hardener of polyester pitches), vtor-butylamine, methylethylketone (antioxidant), etc.
