Products Description of 4-Methyl-2-pentanone CAS#108-10-1

4-Methyl-2-pentanone (methyl isobutyl ketone) reagent is widely used as a solvent in chemical and pharmaceutical industries, separation and recovery of nuclear fission products, and scientific research experiments. The content of 4-methyl-2-pentanone sold on the market is ≤99%, and it contains a small amount of impurities such as alcohol, acidic substances and water. 4-Methyl-2-pentanone is used as a solvent for nitrocellulose, lacquer, and certain polymers and resins. It is also a reactant for the synthesis of 2-(1-hydroxy-3-methylbutyne)-1h-indene-1,3(2H)-dione.

Product Application of 4-Methyl-2-pentanone CAS#108-10-1

Used as medicine and dye intermediate. The pesticide mite produced with o-chlorobenzaldehyde can prevent and control mites on dry crops and fruit trees. The oximation of o-chlorobenzaldehyde can obtain o-chlorobenzaldehyde oxime, and further chlorination can obtain o-chlorobenzaldehyde oxime, both of which are pharmaceutical intermediates.

This product is an excellent medium-boiling point solvent. It is used as a mineral processing agent, a solvent for oil dewaxing, a color film coloring agent, and also as a solvent for tetracycline, pyrethroids and DDT, adhesives, rubber glue, and aircraft and model cloth paint. It is also an effective separation agent for some inorganic salts, and can separate plutonium from uranium, niobium from tantalum, and zirconium from hafnium. Its peroxide is a very important initiator in the polymerization reaction of polyester resins. It is also used in the organic synthesis industry. It can also be used as an anticoagulant and diluent for ethylene resins.
