Production system and method for continuously preparing alkynol di-Grignard reagent

The invention discloses a production system and method for continuously preparing an alkynol di-Grignard reagent. The production system comprises a material supply device for continuously supplying a mono-Grignard reagent and an alkynol solution, a tower reactor and a phase separation tank. The mono-Grignard reagent and the alkynol solution from the material supply device are continuously input to the feeding segment of the tower reactor, and are premixed in the feeding segment through a distributor; the mono-Grignard reagent and the alkynol solution flow through a reaction segment under the action of gravity and undergo a reaction; and the alkynol di-Grignard reagent is continuously extracted, and a residual solution is recycled. The method and the method realize continuous production of the alkynol di-Grignard reagent; and a reaction solvent and unreacted raw materials of a reaction system are recycled, so the raw material utilization rate is improved, and the quality of the prepared alkynol di-Grignard reagent is improved.
