[Safety Profile]

A poison by ingestion. A skin sensitizer upon long or repeated contact. Moderately explosive. When heated to decomposition it emits acrid smoke and fumes and may explode. Explosive reaction with traces of alkaltes, alkali earth hydroxides, halide salts, strong acids, mercury salts + strong acids. See also ACETYLENE COMTOUNDS.

Hazard InformationBack Directory
[General Description]

White to light-brown solid or brownish-yellow aqueous solution. Solid sinks and mixes with water.
[Reactivity Profile]

Pure BUTYNEDIOL(110-65-6) is non-explosvie. Small amounts of certain impurities-alkali hydroxides, alkaline earth hydroxides, halides-may cause explosive decomposition upon distillation. BUTYNEDIOL(110-65-6) should not be treated with basic catalysts in the absence of a solvent at room temperature, and its stability is less with elevated temperatures. In strong acids, contamination with mercury salts can also result in violent decomposition [NFPA 491M 1991].
[Air & Water Reactions]

Water soluble.
[Hazard]

Toxic by ingestion. May explode on con- tamination with mercury salts, strong acids, and alkaline earth hydroxides and halides at high tem- peratures.
[Health Hazard]

May cause dermatitis.
