2-Methyl-1-butanol Chemical Properties,Uses,Production

Chemical Properties

clear colorless to very slighlty yellow 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.


Solvent, organic synthesis (introduction of active amyl group), lubricants, plasticizers, additives for oils and paints.


The active alcohol from fusel oil. The synthetic product is a racemic mixture of both dextroand levorotatory compounds and therefore not optically active.


Moderate fire and explosion risk. Toxic by ingestion, inhalation, and skin absorption.

Safety Profile

Moderately toxic by skin contact and intraperitoneal routes. Mddly toxic by ingestion. An eye, skin, and mucous membrane irritant. Can cause deafness, delirium, headache, nausea, and vomiting. Flammable liquid when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. Incompatible with H2S3. To fight fire, use alcohol foam, spray, mist, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALCOHOLS.

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.

First aid

Skin contact contributes significantly to overall exposure. If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.


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 butanol with CaO, distil, reflux with magnesium and again fractionally distil it. A small sample of highly purified material is obtained by fractional crystallisation after conversion into a suitable ester such as the trinitrophthalate or the 3-nitrophthalate. The latter is converted to the cinchonine salt in acetone and recrystallised from CHCl3 by adding pentane. The salt is saponified, extracted with ether, and fractionally distilled. [Terry et al. J Chem Eng Data 5 403 1960, Beilstein 1 IV 1666.]


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.
