Method and device for continuous hydrolysis and neutralization of vitamin A intermediate double Grignard condensate

The invention discloses a method and a device for continuous hydrolysis and neutralization of a vitamin A intermediate double Grignard condensate. Steps are as follows: an ether solution and acid water containing the vitamin A intermediate double Grignard condensate are respectively pumped into a tubular reactor, and fully mixed by the tubular reactor for continuous hydrolysis to obtain a hydrolysis liquid; alkaline water is pumped into the tubular reactor by another feeding port of the tubular reactor for continuous neutralization with the hydrolysis liquid in the tubular reactor to obtain a neutralization solution; the neutralization solution is discharged from a product discharging port of the tubular reactor, and is layered into a water phase and an organic phase, the water phase is removed, the organic phase is washed with water to neutral, then an organic solvent is recovered by evaporation, and the vitamin A intermediate double Grignard condensate is obtained. The method has the advantages of high mixi
