2-Methyl-3-buten-2-ol Usage And Synthesis

Chemical Properties

Clear colourless to very slightly yellow liquid.
Powerful, oily-herbaceous, somewhat earthy, fungus-like odor of considerable radiance. Poor tenacity.

Uses

2-Methyl-3-buten-2-ol was used to study the kinetics of the gas-phase reaction of OH radicals with 3-methyl-2-butenal.

Uses

2-Methyl-3-buten-2-ol may be used as an analytical reference standard for the determination of the analyte in Humulus Lupulus L. (Hop) and pine-mushroom extracts by chromatography techniques.

Definition

ChEBI: 3-hydroxy-3-methylbut-1-ene is a tertiary alcohol that is 3-methylbut-1-ene carrying a hydroxy substituent at position 3. It has a role as a fragrance, a pheromone, a plant metabolite and an animal metabolite. It is a tertiary alcohol and an olefinic compound. It derives from a hydride of a 3-methylbut-1-ene.

Application

This unsaturated alcohol has found a little use in perfume compositions, mainly in the reconstruction of Lavender and Lavandin oils, etc.
It is occasionally used as a powerful additive in soap and detergent perfumes, but it needs skilful blending and firm fixation in order to control its odor to an acceptable level.

Production Methods

2-Methyl-3-buten-2-ol can be produced from Vinyl magnesium bromide and Acetone by Grignard reaction.

General Description

Colorless liquid.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

An unsaturated aliphatic/alcohol. The unsaturated aliphatic hydrocarbons are generally much more reactive than the alkanes, which are saturated aliphatic hydrocarbons. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Health Hazard

Harmful if inhaled or swallowed. Material is irritating to mucous membrane and upper respiratory tract.

Fire Hazard

Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back.
