Tips for using small stainless steel reactors in experiments

The stainless steel reactor experiment involves the following steps:

1. **Preparation**: Add 250 ml of water to the reactor, secure the lid, and tighten the screws as instructed.

2. **Pressure Test**: Charge the reactor with nitrogen to 0.7 MPa and monitor the pressure for 30 minutes. If the pressure drops, release the nitrogen, check for leaks, and retighten the screws.

3. **Post-Test Actions**: After the pressure test, release the nitrogen and prepare for the reaction process.

4. **Reaction Process**:

- Power on the system to start stirring and heating.

- Maintain a controlled stirring speed and a heating rate of 100°C/hour.

- Cool the stirring shaft with circulating water.

- Heat the reactor to approximately 160°C, recording the pressure at 10°C intervals.

5. **Post-Experiment Steps**:

- Cool the reactor contents to below 80°C using cooling water.

- Release pressure and open the reactor to clean it thoroughly.

- Turn off the cooling water and power supply to complete the process.

These steps ensure safe and effective operation of the stainless steel reactor.
