3-METHYL-2-BUTANOL Chemical Properties,Uses,Production

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.
