Overview

Hydrothermal synthesis autoclave reactor vessel is a closed vessel capable of decomposing insoluble substances. It can be used for pretreatment of dissolved samples in the analysis of atomic absorption spectroscopy and plasma emission; it can also be used for small-dose synthesis reactions; it can also use the strong acid or strong alkali in the tank and the high temperature and high pressure airtight environment to quickly digest insoluble substances. . Sample pretreatment in chemical analysis methods such as gas phase, liquid phase, plasma mass spectrometry, atomic absorption and atomic fluorescence. It is an assistant for digesting samples when determining trace elements and trace elements. It can be used in the determination of heavy metals such as lead, copper, cadmium, zinc, calcium, manganese, iron, mercury, etc. It can also be used as a reaction vessel with high temperature resistance, high pressure resistance, corrosion resistance and high purity, as well as organic synthesis, hydrothermal synthesis, crystal growth or Sample digestion and extraction, etc. Digest heavy metals, pesticide residues, food, sludge, rare earth, aquatic products, organic matter, etc. before sample pretreatment. Therefore, it is widely used in the research and production of petrochemical, biomedical, material science, geochemical, environmental science, food science, commodity inspection and other departments.

Hydrothermal Synthesis Autoclave Reactor Vessel

Hydrothermal synthesis autoclave reactor vessel working principle:

The hydrothermal synthesis autoclave reactor vessel uses aqueous solution as the reaction system under certain temperature and pressure conditions, and uses high temperature and high pressure aqueous solution to dissolve substances that are insoluble or insoluble under atmospheric conditions, or react to form dissolved products of the substance. It is a small reactor commonly used in colleges and universities.

Hydrothermal Synthesis Autoclave Reactor Vessel Structures

How to use hydrothermal synthesis autoclave reactor vessel:

Refer the reactant to the kettle body. When the reactant system is corrosive, it should be placed in a PTFE bushing to ensure that the kettle body is not corroded. Heat up to the required digestion temperature (less than the specified safe use temperature) according to the specified heating rate. When it is cooled down after digestion, it must be operated in strict accordance with the prescribed cooling rate to facilitate safety and the service life of the digestion tank.

After confirming that the intra-abdominal temperature is lower than the boiling point of the solvent of the reactant system, the upper compression wire can be opened for subsequent operations. Clean it in time after each use to avoid rust. Special care should be taken to clean the line seal and prevent it from being bruised or damaged.

Features of hydrothermal synthesis autoclave reactor vessel:

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, and 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 at 180°C within 10 to 30 minutes;

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.

Hydrothermal Synthesis Autoclave Reactor Vessel Features

Notes for hydrothermal synthesis autoclave reactor vessel:

1. The design pressure data of the hydrothermal synthesis autoclave reactor vessel must be obtained from the manufacturer.

2. Compared with high-pressure reactors, hydrothermal synthesis autoclave reactor vessel has a simpler structure and no overpressure unloading device (except for explosion-proof pressure relief vessels), so it is strictly forbidden to use over-temperature and over-pressure to avoid danger!

3. Since the liner of the hydrothermal synthesis autoclave reactor vessel is made of polytetrafluoroethylene, which has the physical characteristics of thermal expansion and contraction, the lid of the hydrothermal kettle should not be tightened too tightly when it is used for the first time, so as to avoid thermal expansion and extrusion of the liner under high temperature resulting in severe deformation.

4. The threads of the hydrothermal synthesis autoclave reactor vessel and the kettle body are coated with white high-temperature lithium-based grease to prevent the stainless steel threads from locking up at high temperatures without wiping.

6. It is strictly forbidden to operate under pressure: after the reaction is over, it is strictly forbidden to quickly drop the temperature of the hydrothermal synthesis autoclave reactor vessel and wait for the kettle body to cool naturally before operating it!

7. Pay attention to the order of the upper and lower pressure gaskets of the hydrothermal synthesis autoclave reactor vessel, and do not reverse them!

8. If the stainless steel casing of the hydrothermal synthesis autoclave reactor vessel is not smooth or deformed when the thread is tightened, stop using it immediately and replace it with a new reactor, and it is strictly forbidden to use it again!

9. After the hydrothermal synthesis autoclave reactor vessel has been reacted under high temperature and high pressure in the oven, the lid of the kettle is in a loose state, and can be unscrewed with light force by hand. If the threads of the kettle lid are locked, it is strictly forbidden to use it again!
