3-Pentanone Chemical Properties,Uses,Production
Chemical Properties
3-Pentanone (also known as diethyl ketone) is a member of the class of compounds known as ketones. 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.3-pentanone is an acetone and ethereal tasting compound and can be found in a number of food items such as strawberry guava, ceylon cinnamon, beech nut, and pak choy, which makes 3-pentanone a potential biomarker for the consumption of these food products.
Uses
3-Pentanone may be used to evaluate excess molar volumes of its binary mixtures with 1-chloroalkanes at 298.15K and atmospheric pressure.
Uses
Diethyl ketone is used as a solvent, inmedicine, and in organic synthesis.
Uses
3-Pentanone is mainly used as a solvent in paint and a precursor to vitamin E. It is used as a reagent to synthesize ethyl 2-cyano-3,3-diethylacrylate by Knoevenagel condensation. It also shows anticonvulsant effect in several types of mouse seizure models. It serves as an intermediate in the manufacture of pharmaceuticals.
Definition
ChEBI: A pentanone that is pentane carrying an oxo group at position 3. It has been isolated from Triatoma brasiliensis and Triatoma infestans.
General Description
A clear colorless liquid with an acetone-like odor. Flash point 55°F. Less dense than water. Vapors heavier than air.
Air & Water Reactions
Highly flammable. Slightly soluble in water
Reactivity Profile
3-Pentanone is incompatible with the following: Strong oxidizers, alkalis, mineral acids, (hydrogen peroxide + nitric acid) .
Health Hazard
Diethyl ketone is a mild narcotic compoundas well as an irritant. Its acute toxicity is lessthan that of methyl propyl ketone. Exposureto 80,000 ppm for 4 hours was fatal to rats.
LD50 value, oral (rats): 2140 mg/kg.
Health Hazard
Liquid causes eye burn. Vapor irritates eyes, nose and throat; can cause headache, dizziness, nausea, weakness, and loss of consciousness.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Flammability and Explosibility
Highly flammable
Safety Profile
Moderately toxic by routes. A skin and eye irritant. Mutation data reported. Dangerous fre hazard when exposed to heat or flame; can react vigorously with oxidzing materials. To fight fire, use alcohol foam, foam, CO2, dry chemical. Reacts with hydrogen peroxide + nitric acid to form a shockand heat sensitive explosive peroxide. When heated to decomposition it emits acrid smoke and irritating fumes. See also KETONES.
Synthesis
Ketonic decarboxylation route
3-Pentanone is produced by ketonic decarboxylation of propanoic acid using metal oxide catalysts:
2 CH3CH2CO2H → (CH3CH2)2CO + CO2 + H2O
in the laboratory, the reaction can be conducted in a tube furnace.
Other way to make 3-pentanone: Acetone + very strong base and then + methylating agent -> butanone. Butanone + very strong base, then + methylating agent -> mixture of 3-methylbutanone and 3-pentanone.

Purification Methods
Dry it with anhydrous CaSO4 or CuSO4, and distil from P2O5 under N2 or under reduced pressure. Further purification is by conversion to the semicarbazone (recrystallise to constant m 139o, from EtOH) which, after drying in vacuo over CaCl2 and paraffin wax, is refluxed for 30minutes with excess oxalic acid, then steam distilled and salted out with K2CO3. Dry with Na2SO4 and distil [Cowan et al. J Chem Soc 171 1940]. [Beilstein 1 IV 3279.]
Waste Disposal
Incineration; molten salt treatment.
