Introduction
In chemical research and industrial production, the reactor is an indispensable laboratory and production equipment. Among them, hydrothermal synthesis reactor and jacketed glass reactor are two common reactor types. They have their own characteristics and are suitable for different reaction conditions and needs. This paper aims to discuss the differences between hydrothermal synthesis reactor and jacketed glass reactor in structure, function, application scenarios and performance characteristics, in order to provide useful reference for experimentators and production personnel.
Hydrothermal synthesis reactor overview
Hydrothermal synthesis reactor, also known as polymerization reactor, high-pressure digestion tank, hydrothermal reactor, etc., is a closed container that uses strong acid or alkali in the tank and a high temperature and high pressure closed environment for chemical reaction.
It is mainly used for the synthesis reaction of small doses, and the rapid digestion of insoluble substances through high temperature and high pressure environment.
Hydrothermal synthesis reactor is widely used in sample pretreatment, organic synthesis, hydrothermal synthesis, crystal growth, sample digestion and extraction in atomic absorption spectrometry and plasma emission analysis. Hydrothermal synthesis reactor plays an important role in the research and production of petrochemical, biomedical, material science, geological chemistry, environmental science, food science, commodity inspection and other departments.
Jacketed glass reactor overview
Jacketed glass reactor is a commonly used reactor product. Its structure design and parameter configuration can realize the functions of heating, evaporation, cooling and low and high speed mixing required by industry.
Jacketed glass reactor adopts double glass design, the inner layer can be put into the reaction solvent to do stirring reaction, and the interlayer can be passed on different cold and hot sources (such as freezing liquid, hot water or hot oil) for circulation heating or cooling reaction. The jacketed glass reactor has the characteristics of variable frequency speed regulation, AC induction motor drive, constant speed, no brush, no spark, safety and stability.
In addition, the glass sandwich interface can be heated by hot oil, low temperature reaction by freezing liquid, and can also react at room temperature, and the reaction heat can be quickly taken away by tap water. Jacketed glass reactor is an ideal pilot and production equipment for modern fine chemical plants, biopharmaceuticals and new material synthesis.
The difference between hydrothermal synthesis reactor and jacketed glass reactor
Structure and material
Hydrothermal synthesis reactor is usually made of stainless steel and equipped with polytetrafluoroethylene bushing to enhance acid and alkali resistance. Its compact structure and simple design require high sealing performance to ensure no leakage in high temperature and high pressure environments. The jacketed glass reactor adopts double glass design, and the jacket is formed between the inner and outer layers, which can pass into different cold and hot sources for temperature control. The jacketed glass reactor is made of glass, which has good chemical stability and transparency, and is easy to observe the reaction process.
Function and application
Hydrothermal synthesis reactor is mainly used for chemical reactions and digestion of insoluble substances under high temperature and pressure. Its sealing performance is strong, can maintain the stability of the reaction system under high temperature and high pressure environment, and achieve rapid digestion of insoluble substances. At the same time, hydrothermal synthesis reactor can also be used for small dose synthesis reaction and sample pretreatment. The jacketed glass reactor is mainly used for stirring reaction under set constant temperature conditions, and can carry out reflux and distillation of reaction solution. Jacketed glass reactor is suitable for chemical reactions in the range of room temperature to high temperature, and has a wide range of applications, such as fine chemical plants, biopharmaceuticals and new material synthesis.
Heating and cooling methods
Hydrothermal synthesis reactor is usually heated by electric heating or steam heating, and the reaction temperature is controlled by controlling the heating power and heating time. In the cooling process, the hydrothermal synthesis reactor needs to be cooled according to the specified cooling rate to avoid damage to the reactor due to excessive temperature difference. The jacketed glass reactor is heated or cooled by intercalating into different hot and cold sources. Its heating and cooling methods are flexible and can be adjusted according to experimental requirements.
Operation and maintenance
Hydrothermal synthesis reactor in the operation process should strictly follow the safety operation procedures to ensure the stability and safety of the reaction system. In the process of use, it is necessary to regularly check and replace the wearing parts such as polytetrafluoroethylene bushing to ensure the performance and life of the reactor. Jacketed glass reactors also need to follow safe operating procedures during operation, but because they are made of glass, special attention needs to be paid to avoid collisions and scratches. In terms of maintenance, jacketed glass reactors need regular cleaning and inspection of the sealing performance of the glass sandwich to ensure its normal operation and service life.
The cooling method is flexible and diverse, the transparency is good, and the reaction process is easy to observe. In practical applications, the experimentalists and production personnel should select the appropriate reactor type according to the specific needs and conditions to ensure the smooth progress of the experiment and production. At the same time, for different types of reactors, safety operation procedures and maintenance requirements should be strictly followed to extend their service life and ensure the safety of experiments and production.
Conclusion
Hydrothermal synthesis reactor and jacketed glass reactor play an indispensable role in chemical research and industrial production. Hydrothermal synthesis reactor, with its stable performance under high temperature and high pressure and strong digestion capacity, has excellent performance in material synthesis and sample pretreatment. Jacketed glass reactors, with their excellent transparency and flexible heating and cooling methods, play an important role in experiments that require observation of the reaction process or precise temperature control. Whether it is laboratory research or industrial production, the correct selection and use of these two reactors can bring higher efficiency and better results for experiments and production.
To sum up, hydrothermal synthesis reactor and jacketed glass reactor each have their own unique advantages and application scenarios, and it is very important to choose the reactor suitable for their own needs to improve the experiment and production efficiency.
