3-METHYL-2-BUTANOL Usage And Synthesis
Chemical PropertiesCLEAR COLOURLESS LIQUID
Chemical PropertiesAmyl alcohols (pentanols) have eight isomers. All are flammable, colorless liquids, except the isomer 2,2- dimethyl-1-propanol, which is a crystalline solid.
Chemical Properties3-Methyl-2-butanol has a fruity, fresh odor.
Uses3-Methyl-2-butanol has been used as a reference for microbially produced, volatile organic compounds (MVOC) in GC-MS analyses.
UsesA flotation agent, a solvent, and in organic synthesis.
DefinitionChEBI: A secondary alcohol that is 2-butanol carrying an additional methyl substituent at position 3.
HazardModerately 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.
ShippingUN2811 Pentanols, Hazard Class: 3; Labels: 3- Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid.
Purification MethodsReflux it with magnesium, then fractionally distil it. [Beilstein 1 IV 1675.]
IncompatibilitiesForms 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 DisposalDissolve 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.
