摘要:
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.
摘要(中):
本发明涉及一种安全运输乙炔形式的乙炔作为乙炔前体的新方法。 新方法包括三个步骤。 在第一步中,α-炔醇的合成通过使乙炔与(a)羰基化合物反应来进行。 第二步包括以安全的方式运输所得的α-炔醇,而这种运输的安全要求不如乙炔那么高,因为α-炔醇通常被分类为危险品类3 在第三步中,α-炔醇可以被切割,并且可以在裂解反应中获得乙炔和羰基化合物,并且可以分离得到用于进一步应用的纯产物。
