| | 3-METHYL-2-BUTANOL Usage And Synthesis |
| Chemical Properties | CLEAR 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. | | Chemical Properties | 3-Methyl-2-butanol has a fruity, fresh odor. | | Uses | 3-Methyl-2-butanol has been used as a reference for microbially produced, volatile organic compounds (MVOC) in GC-MS analyses. | | Uses | A flotation agent, a solvent, and in organic synthesis. | | Definition | ChEBI: A secondary alcohol that is 2-butanol carrying an additional methyl substituent at position 3. | | Hazard | Moderately toxic. | | 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 it with magnesium, then fractionally distil it. [Beilstein 1 IV 1675.] | | 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. |
