Embodiment 1

[0041] 1) Add 50kg of piperonal into the pressure reactor 3 from the upper tank 4 of piperonal, add 250Kg of organic solvent ethanol to the pressure reactor 3 from the upper tank 7 of ethanol, and then add the hand hole 31 from the composite catalyst to the pressure reactor 3Internal dosing with composite catalyst Pd-KF / Al 2 O 3 0.3kg. In this embodiment, the pressure reactor 3 has a volume of 500L.

[0042] 2) Turn on the agitator 32 of the pressure reactor 3, and open the steam valve to raise the temperature of the pressure reactor 3.

[0043] 3) When the pressure reactor 3 is heated to 60-90°C, 19 kg of propionaldehyde is added dropwise from the propionaldehyde high tank 5 to the pressure reactor 3, and the dripping time is controlled at 4-8 hours.

[0044] 4) After the dripping is finished, heat the reaction for 2 to 4 hours. When the content of propionaldehyde is ≤1%, open the circulating cooling water valve to cool the pressure reactor 3 to normal temperature. The cooling wat...

Embodiment 2

[0055] 1) Add 150kg of piperonal into the pressure reactor 3 from the upper tank 4 of piperonal, add 750Kg of organic solvent ethanol to the pressure reactor 3 from the upper tank 7 of ethanol, and then add the hand hole 31 from the composite catalyst to the pressure reactor 3Internal dosing with composite catalyst Pd-KF / Al 2 O 3 1kg. In this step, the pressure reactor 3 has a volume of 1630L.

[0056] 2) Turn on the agitator 32 of the pressure reactor 3, and open the steam valve to raise the temperature of the pressure reactor 3. The steam heats up the pressure reactor 3 through the outer wall.

[0057] 3) When the pressure reaction vessel 3 is heated to 60-90°C, 58 kg of propionaldehyde is added dropwise to the pressure reaction vessel 3 from the propionaldehyde high tank 5, and the dropping time is controlled at 8-10 hours.

[0058] 4) After the dripping is finished, heat preservation and reaction for 3-6 hours. When the content of propionaldehyde is ≤1% by sampling, open the ci...
