Abstract (en)
[origin: DE19635703A1] The invention concerns a process for preparing alkyne diols or mixtures of alkyne diols with alkyne monools by reacting acetylene with more than equimolar amounts of ketones and/or aldehydes in the presence of an alkaline compound, the alkaline compound being used in a molar amount which is less than half the molar amount of the ketone and/or aldehyde to be reacted, in the presence of ammonia and/or at least one reactive primary amine.
