2-Butyne-1,4-diol Usage And Synthesis
Chemical Propertiesyellow solid
UsesBasic brightener in nickel electroplating baths,also an important intermediate for organic synthesis
Uses2-Butyne-1,4-diol is used to produce butanedioland butenediol, in metal plating andpickling baths, and in making the carbamateherbicide Barban (Carbyne).
DefinitionChEBI: A butynediol that is but-2-yne substituted by hydroxy groups at positions 1 and 4.
General DescriptionWhite to light-brown solid or brownish-yellow aqueous solution. Solid sinks and mixes with water.
Air & Water ReactionsWater soluble.
Reactivity ProfilePure 2-Butyne-1,4-diol is non-explosvie. Small amounts of certain impurities-alkali hydroxides, alkaline earth hydroxides, halides-may cause explosive decomposition upon distillation. 2-Butyne-1,4-diol 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].
HazardToxic by ingestion. May explode on con- tamination with mercury salts, strong acids, and alkaline earth hydroxides and halides at high tem- peratures.
Health Hazard2-Butyne-1,4-diol exhibits moderate to hightoxicity in test animals. It is about 10 timesmore toxic than are the saturated C4 diols.The oral LD50 value in rats is 0.125 mL/kg.It causes irritation to the skin.
Health HazardMay cause dermatitis.
Fire HazardNoncombustible solid, flash point (open cup) 152°C (305.6°F). It is stable at room temperature. But the dry compound explodes in the presence of certain heavy metal salts, such as mercuric chloride. Heating with alkaline solution may result in an explosion.
Safety ProfileA 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.
storage2-Butyne-1,4-diol can be stored in steel,aluminum, nickel, glass, epoxy, and phenolicliner containers. Rubber hose may be usedfor transfer. Avoid contact with heavy metalsalt contaminants.
Purification MethodsCrystallise the diol from EtOAc. [Beilstein 1 IV 2687.]
