The double jacketed glass reactor is a standing instrument in the laboratory, which can be stirred and reacted under negative pressure. It has obvious advantages in reaction experiments such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation.
Double-layer glass design is adopted, and high-temperature or low-temperature liquid can be passed into the middle of the interlayer to provide reaction temperature for the experimental materials in the reactor body, so the double jacketed glass reactor can be used for both high-temperature and low-temperature reactions.
The double jacketed glass reactor has good overall sealing performance, and is sealed with PTFE material and special rubber composite sealing ring. It is an equipment for biopharmaceuticals, fine chemicals, and new material synthesis.
Because it is a double jacketed glass reactor precision equipment, the usual use and maintenance are also very important. Today, Jordan will show you what we can do to make the double jacketed glass reactor more efficient?
1. The power supply voltage connected to the double jacketed glass reactor must be higher than the total power of the whole machine according to regulations.
2. When the double jacketed glass reactor is idling, the speed should not be too fast.
3. The installation position of the double jacketed glass reactor is very important. When the ambient temperature is high or the humidity is high, the service life of the electric box will be greatly affected.
4. We usually need to pay attention to keep the governor dry during use.
5. The power connection of the double jacketed glass reactor must have good stability and grounding device.
6. When operating the double jacketed glass reactor, care must be taken to avoid damage to the glass caused by hard objects on the body.
7. Be careful when connecting the double jacketed glass reactor to the circulating water vacuum pump equipment, so as not to damage the glass parts by excessive force.
8. When using high-temperature circulating fluid, the circulating pump must be turned on first to raise the temperature slowly.
9. After the experiment is over, the materials in the double jacketed glass reactor need to be cleaned to avoid contamination of the next experiment.
Proper use of double jacketed glass reactor
1. First, check whether the power supply voltage is consistent with the voltage required on the machine nameplate.
2. Slowly feed the material into the kettle through the feeding port.
3. Set the set speed and start the stirring motor.
4. According to the needs of the reaction, open the supporting vacuum device.
5. According to the needs of the reaction, turn on the matching heating or refrigeration cycle device to meet the temperature control requirements.
6. After the reaction is completed, turn off the heating or cooling function according to the actual situation, and turn off the circulation device when the temperature of the material in the kettle is close to room temperature.
Note: After the temperature-controlled product circulation device is closed, the valve in the circulation pipeline cannot be closed; in order to avoid the glass parts being broken due to thermal expansion and contraction of the liquid.
7. Close the vacuum device.
8. Set the speed to the minimum value and stop stirring.
9. Turn off the power of the controller.
10. Discharge from the discharge port of the discharge valve. After discharging, please remove the discharge valve in time and clean it carefully.
11. Reinstall the discharge valve.
Proper cleaning of double jacketed glass reactor
When cleaning the double jacketed glass reactor body, it is not only time-consuming and labor-intensive, but also not suitable for cleaning.
For instruments with high cleanliness requirements, potassium dichromate lotion can be used to soak and rinse with water, but potassium dichromate is easy to turn green and will pollute the environment. You can also prepare some industrial ethanol, which can be used for drying sodium wire and as laundry detergent. In addition, you can mix an appropriate amount of washing powder water, add some sodium hydroxide, soak the double jacketed glass reactor in the lotion, and then heat it for a while to release the dirty water in the double jacketed glass reactor. Just rinse with water.
When using a double jacketed glass reactor, be sure to close the valve of the refrigerant inlet pipe, drain the residual refrigerant in the reactor and the interlayer, then add the test material, and turn on the agitator. When the desired temperature is reached, first turn off the steam valve and the electric power supply, and then turn off the agitator. After processing, drain the remaining condensed water in the kettle body and the jacket, rinse with warm water, brush off the material, then clean the inner wall of the container with 40-50°C alkaline water, and clean it with clean water.
Chemical cleaning: cleaning with chemical solvents that react with the dirt. This method has obvious effects, but the disadvantage is that the operation is complicated. It is necessary to clarify the components of the dirt on the equipment, and then sample it for analysis, do experiments, and then pass a certain amount of time. Detergent, see if it will react with the equipment, etc., and then go further. If the dosage can be well grasped, the cleaning time will be short and the cleaning effect will be high.
Regular maintenance of double jacketed glass reactor
1. The power supply must be cut off before inspection and maintenance to avoid electric shock or fire.
2. After each use, gently wipe off the dirt on the surface of the machine with a soft cloth to keep it dry and clean.
3. It is recommended to loosen each interface regularly to avoid damage caused by long-term locking of the connecting parts.
4. After use, wait for the machine to stop before turning off the switch.
5. It is forbidden to tighten the PTFE switch with excessive force to prevent damage to the glass. After use, loosen the PTFE switch properly to relax it.
6. Regularly clean the sealing ring. Take off the sealing ring, wipe off all the dirt with a soft cloth, reset the sealing ring, and keep the shaft and the sealing ring lubricated.
7. The electrical part must not enter the water, and it is strictly forbidden to be damp.
The above content is the key factor for how to make the double jacketed glass reactor more efficient. Have you gained a lot after reading it?
