2-Methyl-3-buten-2-ol Chemical Properties,Uses,Production
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.
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.
