| titleOfInvention | An alkynol preparing method |
| abstract | An alkynol preparing method is disclosed. The method includes: (1) feeding acetylene into a metal agent to perform a metal exchanging reaction, after the reaction is finished, controlling the pressure of the acetylene to be 0.3-1.5 MPa, performing a unilateral reaction, and obtaining a unilateral acetylide through online infrared monitoring; and (2) maintaining the pressure of the acetylene to be 0.3-1.5 MPa, adding a carbonyl compound into the unilateral acetylide obtained in the step (1), performing an addition reaction, and after the addition reaction is finished, hydrolyzing to obtain the alkynol. In the preparing method, the pressure of the acetylene is maintained in a proper range, so that the ratio of the unilateral acetylide in the unilateral reaction is controlled, and the yield of the finally obtained alkynol is further increased. |
