The hydrothermal synthesis reactor is a closed vessel that can decompose insoluble substances. The hydrothermal method is used to achieve material processing. In the container, using water or organic solvents as the medium, through the high temperature and high pressure reaction environment, through the separation and heat treatment to get the target product method. Can be used for atomic absorption spectroscopy and plasma emission analysis in the sample pretreatment; can also be used for small doses of synthetic reaction; can also be used in the tank of strong acid or alkali and high temperature and high pressure closed environment to achieve the purpose of rapid dissolution of difficult to dissolve substances. In the gas phase, liquid phase, plasma spectrometry mass spectrometry, atomic absorption and atomic fluorescence and other chemical analysis methods for sample pretreatment.
Hydrothermal Synthesis Reactor is a powerful assistant for the dissolution of samples in the determination of trace elements and trace elements. 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 kind of high-temperature and high-pressure anticorrosive and high-purity reaction vessel, as well as in organic synthesis, hydrothermal synthesis, crystal growth, or sample degradation and extraction. In the sample pretreatment digestion of heavy metals, agricultural residues, food, sludge, rare earths, aquatic products, organic matter. Therefore, it is widely used in the research and production of petrochemical, biomedical, material science, geological chemistry, environmental science, food science, commodity inspection and other departments.
Hydrothermal synthesis reactor theoretical filling is 60% ~ 80%, in which the ligand solubility is small, the filling degree can be slightly larger, the pressure will also be increased accordingly, but it is not appropriate to fill too much, otherwise the pressure increases to the reactor can not adapt to the degree of time, a series of accidents will occur in the reactor damage, the safety of the operating elements. Of course, if you want to deliberately adjust the pressure in the kettle, in addition to increase the degree of filling, you can also consider the use of solvent water with some organic solvents, or directly a certain proportion of mixed solvents thermal reaction, but pay attention to the operating temperature, do not operate outside the temperature range of the reaction kettle.
