Methods of cleaning miniature high-pressure reactor:
1. Charge the reaction solvent from the exhaust valve into the kettle, clean off most of the residues, inject water and a half kettle for stirring for 10 minutes, at this time before you can open the kettle cover, the high-pressure reaction kettle inner wall cleaning;
2. When cleaning, the kettle cover and sampling valve must be cleaned, and at the same time, the kettle should be slightly filled with nitrogen when there is water in the kettle;
3. The reactor that is not used for a while, it is better to add 70% volume of clean anhydrous ethanol to soak in the reactor, and you can not tighten the screws.
4. After the autoclave is cleaned, the party can facilitate the next use.
Knowledge point extension:
The autoclave belongs to the precision equipment, through the sealing ring adopts the conical surface contact sealing form, by tightening the main bolt to make them press each other to achieve the purpose of sealing. The sealing cone surface must be particularly cared for to avoid all kinds of collision and lead to its damage. When installing the cover, first place the kettle kettle body, and then the kettle cover according to the fixed position, carefully installed in the kettle body, in tightening the main bolt, must be diagonal, symmetrical and gradually tightened in several times, the force should be uniform, do not allow the kettle cover to tilt to one side, in order to achieve a good sealing effect, do not exceed the tightening torque, in order to prevent the sealing surface is squeezed or accelerated wear and tear.
