Abstract
The disclosure discloses a method for an addition reaction of acetylene and a ketone compound. The method includes the following steps: S1, providing a continuous reaction device, wherein the continuous reaction device includes a plurality of bubble tubular reactors being connected with each other through connecting tubes; feeding a raw material solution containing the ketone compound and alkali into the plurality of bubble tubular reactors, and S3, under normal pressure, pumping acetylene from the bottom of the first bubble tubular reactor for the addition reaction. By applying the technical solution of the invention, acetylene reacts with the ketone compound in the plurality of bubble tubular reactors arranged in series, which can ensure the sufficient gas-liquid contact time, and thus making full use of the acetylene gas, improving the utilization rate thereof, effectively reduing the amount of acetylene, reducing costs, and further improving the safety.
