1. The hydrothermal synthesis autoclave reactorhas good corrosion resistance, no harmful substance overflow, less pollution, and safe use. After heating up and boosting pressure, it can quickly and without loss dissolve samples that are difficult to dissolve under normal conditions and samples containing volatile elements. sample.

2. The hydrothermal synthesis autoclave reactorhas beautiful appearance, reasonable structure, simple operation, shortened analysis time and reliable data. It has polytetrafluoroethylene lining inside, double-layer care, and can resist acid and alkali.

3. The hydrothermal synthesis autoclave reactorhas strong interference ability, adopts needle valve, reciprocating closing form, reliable and durable sealing, and reasonable installation of various valves.

4. The hydrothermal synthesis autoclave reactoralso has the characteristics of high precision and easy operation.

Operation Method of Hydrothermal Synthesis Autoclave Reactor:

1. Pour the reactant into the PTFE bushing or PPL bushing, and ensure that the feeding coefficient is less than 0.8.

2. Make sure the position of the gasket under the kettle body is correct (the raised side is facing down), then put in the PTFE bushing or PPL bushing and the upper gasket, first tighten the kettle cover, and then use the screw to tighten the kettle cover until . Put the hydrothermal synthesis autoclave reactorin the heater, and raise the temperature to the required reaction temperature according to the prescribed heating rate. (less than the specified safe operating temperature).

3. After confirming that the temperature in the kettle is lower than the boiling point of the solvent of the reactant system, the lid of the kettle can be opened for subsequent operations. When the reaction is finished and the temperature is lowered, it is also necessary to operate in strict accordance with the prescribed cooling rate to facilitate safety and the service life of the reactor.

4. After confirming that the temperature in the kettle is lower than the boiling point of the solvent of the reactant system, first use the screw to loosen the lid of the kettle, and then open the lid of the kettle.

5. The hydrothermal synthesis autoclave reactorshould be cleaned in time after each use to avoid corrosion. Special attention should be paid to cleaning the line seals of the kettle body and the kettle cover, and strictly preventing them from being damaged by bumps.

Features of Hydrothermal Synthesis Autoclave Reactor:

1. Safety, from passive temperature control to active pressure control, safety is fully considered in the design.

2. Less solvent consumption and low blank value. The PTFE inner cup ensures no container adsorption, and the acid will not be volatilized and lost during the closed digestion process. It is not necessary to continue to add acid to maintain the capacity of the acid, saving reagents, reducing the interference of impurity elements brought in by reagents, and greatly reducing Analyze blank values.

3. It has high digestion efficiency and strong ability. It can digest many samples that are difficult to digest by traditional methods. It has a wide range of applications and can replace microwave digestion (some samples are not suitable for microwave digestion). It is especially suitable for large-scale sample testing, and generally insoluble samples can be dissolved within 10-30 minutes at 180°C.

4. Improve the accuracy and precision of analysis, reduce work intensity and environmental pollution. The use of a closed digestion tank avoids the loss of volatile components in the sample or during the digestion process, prevents cross-contamination of samples, and is suitable for trace and ultra-pure analysis and detection of volatile elements.

5. Low cost and easy to use. The early and late investment is very little, the operation is easy, the operator hardly needs training before use, and the maintenance is simple.

Precautions for Using Hydrothermal Synthesis Autoclave Reactor:

1. The design pressure data of the hydrothermal synthesis autoclave reactormust be obtained from the manufacturer. Before the experimental reaction, please check the saturated vapor pressure of the solvent used at the required reaction temperature to confirm that it will not exceed the safe pressure before use.

2. Compared with the high-pressure reactor, the structure of the hydrothermal synthesis autoclave reactoris simpler, and there is no overpressure unloading device (except for the explosion-proof pressure relief kettle), so it is strictly forbidden to use it at overtemperature and overpressure to avoid danger!

3. Since the liner of the hydrothermal synthesis autoclave reactoris made of polytetrafluoroethylene, it has the physical characteristics of thermal expansion and contraction. When using it for the first time, the lid of the hydrothermal synthesis autoclave reactorshould not be tightened too tightly, so as to avoid the thermal expansion and extrusion of the inner liner at high temperature. Severe deformation occurs.

4. The thread of the lid and body of the conventional hydrothermal synthesis autoclave reactoris coated with white high-temperature lithium-based grease to prevent the stainless steel thread from locking at high temperature, and no need to wipe.

5. It is strictly forbidden to use the hydrothermal synthesis autoclave reactorfor reactions with one of the following characteristics:

·The boiling point of the solvent is lower than 60°C (such as acetone, dichloromethane, etc.).

·Gas generated during the reaction (ammonia, hydrogen peroxide, etc.).

·Materials are flammable, explosive or extremely toxic.

6. It is strictly forbidden to operate under pressure: After the reaction is over, it is strictly forbidden to quickly cool down the hydrothermal synthesis autoclave reactor(such as putting the kettle directly into the water or cooling it with water), and the operation can only be performed after the kettle body cools down naturally!

7. Pay attention to the order of the upper and lower pressure gaskets of the water heating kettle, and do not put them backwards!

8. If the stainless steel shell of the water heating kettle is not smooth or deformed when the thread is tightened, stop using it immediately and replace it with a new one. It is strictly forbidden to use it again!

9. After the hydrothermal synthesis autoclave reactorhas undergone high temperature and high pressure reaction in the oven, the lid of the kettle is in a loose state, and it can be unscrewed with light force by hand. If the lid of the kettle is locked, it is strictly forbidden to use it again!
