Diethyl ketone Chemical Properties,Usage,Production

Chemical Properties

Diethyl Ketone is a colorless liquid with an Acetone-like (nail polish remover) odor. It is used in chemical manufacturing and in medicine.

Definition

Pentan-3-one is a pentanone that is pentane carrying an oxo group at position 3. It has been isolated from Triatoma brasiliensis and Triatoma infestans. It has a role as an animal metabolite.

Uses

Diethylketone (or 3-Pentanone) is a colorless liquid which is mainly used as solvent.

Safety

The TLV value for 3-pentanone is 200 ppm (705 mg/m3).[3] 3-pentanone can be hazardous if it comes in contact with the skin or eyes, and can cause irritation of the skin and redness, watering, and itching of the eyes. This chemical can also cause nervous system or organ damage if ingested. Although considered stable, 3-pentanone is extremely flammable if exposed to flame, sparks, or another source of heat. For safety, it should be stored in a flammable materials cabinet away from heat or sources of ignition, preferably in a cool, well-ventilated area.

References

Diethyl ketone appears as a clear colorless liquid with an acetone-like odor. Flash point 55°F. Less dense than water. Vapors heavier than air.
3-Pentanone (also known as diethyl ketone) is a simple, symmetrical dialkyl ketone. It is a colorless liquid ketone with an odor like that of acetone. It is soluble in about 25 parts water, but miscible with organic solvents.
