1-HEXYN-3-OL Chemical Properties,Uses,Production

Chemical Properties

Light-yellow liquid; strong odor. Slightly soluble in water; miscible with most hydrocarbons, chlorinated solvents, ketones, alcohols, and glycols.

Uses

1-Hexyn-3-ol may be used in the synthesis of racemic 3-hydroxy-2-hexanone. It may also be used in the preparation of 1,2,3-triazoles.

Uses

Corrosion inhibitor against mineral acids, hightemperature oil-well-acidizing inhibitor.

General Description

1-Hexyn-3-ol is a terminal propargylic alcohol. It undergoes microwave-accelerated coupling-isomerization reaction (MACIR) with (hetero)aryl halides to afford the corresponding enone.

Hazard

Toxic by ingestion and inhalation, absorbed by skin. Probably flammable.
