1,4-Butynediol can be produced in the Reppe synthesis, where formaldehyde and acetylene are the reactants:2 CH2O + HCCH → HOCH2CCCH2OH
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. Applications
1,4-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. It is the major raw material of vitamin B6. It is also used for brightening, preserving, and inhibiting nickel plating. Safety
1,4-Butynediol is corrosive and irritates the skin and eyes.
