ABSTRACT:
Butynediol is prepared by reacting acetylene and formaldehyde in contact with a heavy metal acetylide as catalyst, in the liquid phase by the Reppe method. Acetylene is fed upwardly through a suspension of the catalyst in formaldehyde at such a rate that it is virtually completely consumed and a liquid zone containing no catalyst is formed above the suspension.
