100ml hydrothermal synthesis reactorThe safety operating procedures are crucial for ensuring the safety and smooth progress of experiments. Here is a detailed safety operating procedure:

1、 Preparation stage

1. Check the equipment:

Check whether the appearance of the hydrothermal synthesis reactor is intact, without cracks, deformations, or other damages.

Ensure that the kettle cover, sealing ring, and other components are intact and free from aging, cracking, and other phenomena.

Check whether the heating system, temperature control system, pressure gauge and other equipment are working properly to ensure that there are no safety hazards such as leakage and short circuit.

2. Prepare experimental materials:

Prepare the necessary experimental drugs and equipment, and ensure that they are clean, dry, and free of impurities.

Understand the properties and hazards of experimental drugs in order to take appropriate measures in emergency situations.

2、 Operation phase

1. Feeding:

Pour the reactants into the PTFE liner or PPL liner according to the experimental requirements, and ensure that the feeding coefficient is less than 0.8 (or 70% of the total volume, and not more than 80% for explosion-proof kettles).

When adding materials, avoid splashing or spilling to prevent safety accidents.

2. Assembly:

Ensure that the position of the gasket under the kettle body is correct (with the protruding surface facing downwards).

Insert PTFE or PPL liner and upper gasket.

First, gently tighten the kettle lid by hand to ensure a good seal.

Then use screws to tighten the kettle lid until the specified tightening torque is reached. Pay attention to applying even force to avoid damaging the threads.

3. Heating up:

Translate into English100ml hydrothermal synthesis reactorPlace it inside the heater.

Heat up to the required reaction temperature according to the prescribed heating rate, with a recommended heating rate not exceeding 5 ℃/min.

During the heating process, closely monitor temperature changes to avoid creating excessive temperature gradients. Meanwhile, pay attention to the changes in the pressure gauge to ensure that the pressure inside the kettle is within a safe range.

4. Reaction:

When the set reaction temperature is reached, start timing.

Pay close attention to experimental phenomena during the reaction process. If there is any abnormality, the reaction should be stopped immediately and corresponding safety measures should be taken.

Ensure that the reactor is in a well ventilated environment to promptly release any harmful gases produced.

3、 End stage

1. Cooling:

After the reaction is complete, the cooling operation should be carried out according to the prescribed cooling rate, and the cooling rate is also recommended not to exceed 5 ℃/min.

During the cooling process, it is necessary to closely monitor temperature changes and pressure gauge changes to avoid excessive temperature gradients or pressure fluctuations.

After the temperature inside the kettle drops to room temperature (and is lower than the boiling point of the reactant solvent), subsequent operations can be carried out.

2. Disassembly and cleaning:

After confirming that the temperature inside the kettle has dropped to room temperature, first use a screw to unscrew the kettle cover.

Open the kettle lid and remove the liner and gasket for cleaning.

When cleaning, use clean water or mild cleaning agents, and avoid using organic solvents or other flammable substances.

Pay attention to cleaning the sealing parts of the kettle body and kettle cover, and strictly prevent them from being damaged or bumped.

4、 Precautions

1. It is strictly prohibited to use it under excessive temperature and pressure: Set the appropriate maximum operating temperature and pressure range according to the different materials of the kettle body and lining. Using beyond this range may result in equipment damage or safety accidents.

2. Avoid direct sunlight and exposure to wind and rain: During operation, avoid exposing the hydrothermal synthesis reactor to the external environment. Meanwhile, maintain a clean and dry operating environment to prevent dust and moisture from entering the interior of the equipment.

3. Comply with laboratory safety regulations: Strictly follow laboratory safety regulations and operating procedures, wear corresponding protective equipment (such as lab coats, gloves, goggles, etc.) to ensure personal safety.

Following the above safety operating procedures can ensure100ml hydrothermal synthesis reactorSafe and efficient operation during the experimental process.
