ABSTRACT:
The present invention relates to a new method for a safe transport of ethyne in form of α-alkynols as precursors for ethyne. The new method comprises three steps. In a first step the synthesis of the α-alkynol(s) is performed by reacting ethyne with (a) carbonyl compound(s). The second step comprises the transport of the resulting α-alkynol(s) in a safe manner, whereas the safety requirements for this transport are not as high as for ethyne because α-alkynol(s) are normally classified for transportation as hazardous class 3. In the third step the α-alkynol(s) can be cleaved and the ethyne and the carbonyl compound(s) can be obtained in the cleavage reaction and can be separated to yield pure products for further applications.
