Introduction to hydrothermal synthesis reactor
Hydrothermal synthesis reaction kettle, also known as polymerization reaction kettle, digestion tank, high-pressure digestion tank, high-pressure tank, reaction kettle, pressure dissolution bomb, digestion tank, hydrothermal synthesis kettle, experimental reaction kettle.
A hydrothermal synthesis reactor is a closed container capable of decomposing insoluble substances. Can be used for sample pretreatment in atomic absorption spectroscopy and plasma emission analysis; It can also be used for low-dose synthetic reactions; The purpose of rapidly dissolving insoluble substances can also be achieved by using a sealed environment with strong acid or alkali inside the tank and high temperature and high pressure. Sample pretreatment is performed in chemical analysis methods such as gas phase, liquid phase, plasma chromatography-mass spectrometry, atomic absorption, and atomic fluorescence. It is a powerful assistant for the determination of trace elements and the digestion of samples during trace element analysis. It can be applied in the determination of heavy metals such as lead, copper, cadmium, zinc, calcium, manganese, iron, mercury, etc. It can also be used as a high-temperature, high-pressure, corrosion-resistant, high-purity reaction vessel, as well as in organic synthesis, hydrothermal synthesis, crystal growth, or sample digestion and extraction. Dissolve heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc. before sample preparation. Therefore, it is widely used in research and production in departments such as petrochemicals, biomedicine, materials science, geochemistry, environmental science, food science, and commodity inspection.
1. Characteristics of hydrothermal synthesis reactor
1. Good corrosion resistance, no harmful substances overflow, reduced pollution, and safe use.
2. After heating and boosting, it can quickly and non destructively dissolve samples that are difficult to dissolve under conventional conditions and samples containing volatile elements.
3. Beautiful appearance, reasonable structure, simple operation, shortened analysis time, and reliable data.
4. There is a polytetrafluoroethylene lining inside, which provides care and is resistant to acid, alkali, and other substances.
5. Can replace platinum crucibles to solve the problem of sample dissolution for trace element analysis in high-purity alumina. The high-pressure digestion tank used in the oven, also known as the dissolution apparatus, pressure dissolution bomb, hydrothermal synthesis reactor, digestion tank, or polytetrafluoroethylene high-pressure tank, is a device that utilizes a strong acid or strong alkali and a high-temperature, high-pressure, and sealed environment inside the tank to achieve rapid digestion of insoluble substances. It is a powerful assistant for the determination of trace elements and the digestion of samples during trace element analysis. Sample pretreatment for digestion of heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc.
2. Operation method of hydrothermal synthesis reactor
◆ Before use, soak the PTFE inner cup in acid solution (due to experimental requirements) for a period of time to clean the attachments on the surface of the PTFE cup.
Pour the reactants into a PTFE liner or PPL liner, and ensure that the feeding coefficient is less than 80%.
Ensure that the position of the gasket under the kettle body is correct (with the protrusion facing downwards), then place the PTFE liner or PPL liner and upper gasket, tighten the kettle cover first, and then use screws to tighten the kettle cover until it is tight.
Place the hydrothermal synthesis reactor in the heater and heat it up to the desired reaction temperature at the specified heating rate. (Below the specified safe operating temperature).
After confirming that the temperature inside the abdomen is lower than the boiling point of the reactant solvent, the kettle lid can be opened for subsequent operations. When the reaction is completed and cooled down, it is also necessary to strictly follow the prescribed cooling rate (less than 5 ℃) for safety and the service life of the reaction kettle.
After confirming that the temperature inside the abdomen is lower than the boiling point of the reactant solvent, first use a screw to unscrew the kettle cover, and then open the kettle cover.
The hydrothermal synthesis reactor should be cleaned promptly after each use to prevent rusting. Special attention should be paid to cleaning the sealing parts of the kettle body and kettle cover line, and strict precautions should be taken to prevent them from being damaged or bumped.
3. Material of hydrothermal synthesis reactor
The kettle body is made of high-quality 304 stainless steel, sealed with circular mortise and tenon grooves, and sturdy with manual screw Has good sealing performance, high safety factor, consumes less acidic solvents, and is easy to use!
The inner liner material is polytetrafluoroethylene (PTFE, abbreviated as F4), and its characteristics are:
1. High temperature resistance: operating temperature range from 0 to+200 ℃;
2. Corrosion resistance: resistant to strong acids, strong alkalis, aqua regia, and various organic solvents;
3. Insulation resistance: The dielectric performance is independent of temperature and frequency;
4. High lubrication: The lowest friction coefficient in solid materials;
5. Non adhesive: does not adhere to any substance; Strong self lubrication: The friction coefficient in solid materials is 0.04
6. Non toxic: physiologically inert, can be implanted into the human body; Resistant to aging and can be used in the atmosphere for a long time
7. Pollution prevention: The blank value of metal elements is low, the lead content is less than 10-11 g/ml, and the uranium content is less than 10-12 g/ml;

4. Precautions and protective measures:
1. When in use, it is strictly prohibited to use it beyond the maximum operating temperature and pressure. The maximum working pressure is 3MPa (gauge pressure).
2. The maximum capacity of the reaction cup is 80%. If the gas production rate of the reactants is high, it is recommended to perform cold nitrification overnight, especially when using perchloric acid, hydrogen peroxide, etc!
3. The quality of the oven should be good, and the actual temperature control of the oven should reach plus or minus 2 degrees. It is important to pay attention to the temperature overshoot of the oven. Note: Some ovens may experience a temperature overshoot of up to 20 degrees, which is more pronounced at high temperatures. It is recommended to set the temperature in sections.
4. When the oven starts to heat up, no one is allowed in the room to prevent explosion and injury! Only enter after cooling to room temperature, and necessary safety precautions should be taken when taking out the can, such as facial protection, hand protection, respiratory protection, etc.
