| 3-Pentanol Usage And Synthesis |
| Chemical Properties | colourless liquid | | Chemical Properties | Amyl alcohols (pentanols) have eight isomers.
All are flammable, colorless liquids, except the isomer 2,2-
dimethyl-1-propanol, which is a crystalline solid. | | Uses | 3-Pentanol is widely used as a flavoring agent. It is biogenic oxygenated volatile organic compound (BOVOC) and is used as a reagent in the synthesis of pure bromopentanes for infrared standards. | | Uses | 3-Pentanol can be used as: - A starting material for the preparation of liquid crystals, 1-ethylpropyl (R)-2-[4-(4′-alkoxybiphenylcarbonyloxy)-phenoxy]propionates by reacting with chiral (S)-lactic acid.
- Solvent/reductant in the catalytic deoxydehydration reaction of C4?C6 sugar alcohols into linear polyene using methyltrioxorhenium as a catalyst.
- A reactant for the synthesis of 3-(4-bromophenyloxy)pentane by reacting with 4-bromophenol via base-catalyzed Mitsunobu reaction.
| | Definition | ChEBI: A secondary alcohol that is pentane substituted at position 3 by a hydroxy group. | | Potential Exposure | (n-isomer); Suspected reprotoxic hazard,
Primary irritant (w/o allergic reaction), (iso-, primary):
Possible risk of forming tumors, Primary irritant (w/o allergic
reaction), (sec-, active primary-, and other isomers)
Primary irritant (w/o allergic reaction). Used as a solvent in
organic synthesis and synthetic flavoring, pharmaceuticals,
corrosion inhibitors; making plastics and other chemicals;
as a flotation agent. The (n-isomer) is used in preparation
of oil additives, plasticizers, synthetic lubricants, and as a
solvent. | | Shipping | UN2811 Pentanols, Hazard Class: 3; Labels: 3-
Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class:
3; Labels: 3-Flammable liquid. | | Purification Methods | Reflux the alcohol with CaO, distil, then reflux it with magnesium and again fractionally distil it. [Beilstein 1 IV 1662.] | | Incompatibilities | Forms an explosive mixture with air.
Contact with strong oxidizers and hydrogen trisulfide may
cause fire and explosions. Incompatible with strong acids.
Violent reaction with alkaline earth metals forming hydrogen,
a flammable gas. | | Waste Disposal | Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator
equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. |
