1,4-Butynediol is an organic compound that is an alkyne and a diol. This yellow crystalline solid is soluble in water and ethanol. Additional recommended knowledge
Synthesis1,4-Butynediol can be produced in the Reppe synthesis, where formaldehyde and acetylene are the reactants:
Several patented production methods use copper bismuth catalysts coated on an inert material. The normal temperature range for the reaction is 90°C up to 150°C, depending on the pressure used for the reaction which can range from 1 to 20 bar.[2] Applications1,4-Butynediol is a precursor to 1,4-butanediol. It is also used in the manufacture of plant protection agents, pesticides, textile additives, corrosion inhibitors, platicizers, synthetic resins, and polyurethanes.[3] It is the major raw material of vitamin B6.[4] It is also used for brightening, preserving, and inhibiting nickel plating. Safety1,4-Butynediol is corrosive and irritates the skin and eyes.[3] References
