[0036] Example 1:
[0037] A variable pressure controllable gas displacement reaction device, comprising a reaction vessel 4, a measuring cylinder 20 and a base 25, the reaction vessel 4 and the measuring cylinder 20 are fixed on the upper surface of the base 25;
[0038] The reaction kettle 4 is made of high pressure resistant materials, and its pressure resistance limit is not less than 5MPa;
[0039] In order to facilitate the external observation of the liquid level change inside the reactor 4, the side wall of the reactor 4 is provided with a vertical observation window 7. The observation window 7 is a transparent pressure-resistant glass plate, which is integrated with the reactor 4 and maintains the entire The tightness and pressure resistance of the reactor 4.
[0040] The upper openings of the reaction kettle 4 and the measuring cylinder 20 are respectively covered with a reaction kettle sealing cover 5 and a measuring cylinder sealing cover 21. Further, the reaction kettle 4...
