Reppe chemistry

Walter Reppe discovered that in the presence of metal catalysts, acetylene can react to give a wide range of industrially significant chemicals.

• With alcohols, hydrogen cyanide, hydrogen chloride, or carboxylic acids to give vinyl compounds:

• With aldehydes to give ethynyl diols.

1,4-Butynediol is produced industrially in this way from formaldehyde and acetylene.

• With carbon monoxide to give acrylic acid, or acrylic esters, which can be used to produce acrylic glass.

• Cyclicization to give benzene and cyclooctatetraene:
