2- pentanone, is a chemical compound from the group of ketones. It is in the form of a colorless liquid with acetone -like odor and is isomeric to 3-pentanone and methyl.

Production and representation

2- pentanone can be obtained eg from ethyl acetoacetate. Further, it is formed by oxidation of 2- pentanol.

Properties

The miscibility with water is limited. With increasing temperature, the solubility of 2 -pentanone in water decreases or increases the solubility of water in 2- pentanone.

Use

2 -pentanone is employed as a solvent for organic synthesis, and odorant.

Safety

The vapors of 2- pentanone are 2.97 times heavier than air and, together with this explosive mixture (flash point 7 ° C, ignition temperature 445 ° C).
