PROPARGYL ALCOHOL
Propargyl alcohol, or 2-propyn-1-ol, is an organic compound with the formula C3H4O.
It is the simplest stable alcohol containing an alkyne functional group.
Propargyl alcohol is a colorless viscous liquid that is miscible with water and most polar organic solvents.
Propargyl alcohol appears as a clear colorless liquid with a geranium-like odor. Flash point 97°F. Vapors are heavier than air. Used to make other chemicals, as a corrosion inhibitor and a soil fumigant.
Reactions and applications
Propargyl alcohol polymerizes with heating or treatment with base. It is used as a corrosion inhibitor, a metal complex solution, a solvent stabilizer and an electroplating brightener additive.
It is also used as an intermediate in organic synthesis.
Secondary and tertiary substituted propargylic alcohols undergo catalyzed rearrangement reactions to form α,β-unsaturated carbonyl compounds via the Meyer–Schuster rearrangement and others.
It can be oxidized to propynal or propargylic acid.
Preparation
Propargyl alcohol is produced by the copper-catalysed addition of formaldehyde to acetylene as a by-product of the industrial synthesis of but-2-yne-1,4-diol.
It can also be prepared by dehydrochlorination of 3-chloro-2-propen-1-ol by NaOH.
Propargyl alcohol is a flammable liquid, toxic by inhalation, highly toxic by ingestion, toxic by skin absorption, and corrosive
IUPAC name: Prop-2-yn-1-ol. Other names: propynol, 2-propynol, 2-propyn-1-ol, prop-2-yn-1-ol, hydroxymethylacetylene.
