Product Introduction

 

The working principle of a hydrothermal reactor involves creating a controlled environment of temperature and pressure to facilitate chemical reactions in a water-based solvent. Here is a description of its working principle:

◆ Loading: The reactants and the appropriate solvent are loaded into the reaction vessel of the hydrothermal  reactor. The vessel is then sealed tightly to ensure no leakage during the reaction.

◆ Heating: The heating system of the reactor is activated, and heat is applied to raise the temperature inside the vessel. The temperature is carefully controlled based on the requirements of the specific reaction.

 

hydrothermal synthesis reactor structure

 

◆ Pressurization: As the temperature increases, the pressure inside the reactor also rises. This can be achieved either by directly heating the solvent or by adding a gas or liquid that generates pressure upon heating.

◆ Reaction: With the desired temperature and pressure set, the chemical reaction takes place within the reactor. The high temperature and pressure conditions promote reaction rates and allow for unique reaction pathways, resulting in the desired product formation.

◆ Cooling and Depressurization: Once the reaction is complete, the heating is turned off, and the reactor is allowed to cool down. Cooling can be accomplished naturally or by using a cooling system. After cooling, the pressure inside the reactor is gradually released, either by manual venting or through a pressure relief valve.

◆ Product Collection: After depressurization, the reaction mixture is collected for further analysis or purification. The products obtained from the hydrothermal synthesis are typically characterized by their unique morphology, structure, and composition due to the specific reaction conditions.

Operation Method

hydrothermal synthesis reactor operation

During the operation of a hydrothermal synthesis reactor, it is important to observe certain precautions to ensure safe and efficient use. Here are some important considerations:

► Safety Measures

* Wear appropriate personal protective equipment (PPE) such as gloves, lab coat, and safety goggles throughout the experiment.

* Ensure proper ventilation in the laboratory to prevent the buildup of potentially hazardous gases.

*Handle hot surfaces and pressurized vessels with caution, using appropriate heat-resistant gloves and safety precautions.

► Reactant Selection

* Choose suitable reactants and solvents with consideration for their compatibility with the reactor material and the desired reaction conditions.

* Avoid using highly reactive or explosive materials that may pose a safety risk.

► Loading and Sealing

* Carefully load the reactants into the reactor vessel, following the recommended guidelines and avoiding overfilling.

* Ensure proper sealing of the reactor to prevent leakage or loss of pressure during the reaction.

► Temperature and Pressure Control

* Set the temperature and pressure parameters within the recommended range for the specific reaction.

* Use a reliable and calibrated temperature controller to maintain accurate and stable temperature conditions.

* Regularly monitor and record the temperature and pressure during the reaction.

► Cooling and Depressurization

* Allow sufficient time for the teflon lined autoclave 100 ml to cool down before opening to avoid potential thermal hazards.

* Gradually release the pressure inside the teflon lined stainless autoclave using appropriate methods, such as venting or using a pressure relief valve.

► Post-Reaction Handling

* After the reaction, handle the autoclave for hydrothermal synthesis and the reaction mixture carefully to avoid spills or accidents.

* Dispose of the reaction mixture and any waste materials following appropriate procedures and regulations.

► Maintenance and Cleaning

* Regularly inspect the reactor for any signs of damage or wear and perform maintenance as needed.

* Thoroughly clean the reactor after each use, using appropriate cleaning agents and procedures recommended for the lining material.

Reaction process monitoring

 

Comprehensive and meticulous monitoring is required during the reaction process in a hydrothermal synthesis reactor to ensure the reaction proceeds safely and efficiently and to obtain the desired products. The following is an introduction from aspects such as monitoring parameters, monitoring methods, and handling of abnormal situations:

Monitoring parameters
Hydrothermal Synthesis Reactor | Shaanxi Achieve chem-tech
01

Temperature

Temperature is one of the key parameters in hydrothermal synthesis reactions, directly affecting the reaction rate and the properties of the products. For instance, when synthesizing certain crystalline materials, even minor changes in temperature may lead to alterations in the crystal structure. Therefore, it is necessary to precisely control the reaction temperature and monitor its fluctuation in real time. Generally, the temperature fluctuation should be controlled within a small range, such as within ±1℃.

02

Pressure

Pressure has a significant impact on the solubility and reactivity of the reacting substances. Appropriate pressure helps to increase the reaction yield and product purity. In hydrothermal synthesis reactions, the pressure is usually high. It is necessary to closely monitor the pressure changes to ensure that the pressure fluctuates within a safe range.

03

Liquid level

The level of the liquid in the reactor will affect the concentration of the reactants and the extent of the reaction. Too low a liquid level may lead to insufficient reactants, affecting the reaction effect. If the liquid level is too high, it may increase the pressure in the reactor, posing a safety hazard. Therefore, it is necessary to monitor the liquid level in real time to ensure that it is within the appropriate range.

04

pH value

For some reactions that are sensitive to acidity or alkalinity, the monitoring of pH value is of vital importance. The change of pH value may affect the activity of reactants and the generation of products. For instance, in some biological mineralization reactions, even a slight change in pH value may lead to significant alterations in the morphology and structure of the products.

Monitoring method
 
 
Sensor monitoring

Install temperature sensors, pressure sensors, liquid level sensors, pH sensors, etc., to collect relevant parameters during the reaction process in real time and transmit the data to the monitoring system. These sensors feature high precision and reliability, and are capable of accurately reflecting the actual conditions inside the reactor.

 
Online analysis technology

By using online spectral analysis, online chromatographic analysis and other technologies, the composition and concentration of substances in the reaction system are monitored in real time. For instance, through online infrared spectroscopy analysis, the consumption of reactants and the generation of products can be understood in real time.

 
Image monitoring

Real-time image monitoring of the reaction conditions inside the reactor is conducted using cameras to observe the state changes of reactants, such as whether there is precipitation formation or crystal growth.

 
 
 
 
Handling of abnormal situations
01.

Abnormal temperature

If the temperature is too high, it may trigger side reactions or cause damage to the reactor. At this time, heating should be stopped immediately and cooling measures should be taken, such as introducing cooling water or turning on the cooling fan. If the temperature is too low, the reaction rate may slow down. The heating power can be appropriately increased, but it is necessary to avoid excessive temperature fluctuations.

02.

Abnormal pressure

When the pressure exceeds the safety threshold, the pressure relief valve should be opened immediately to release the pressure, and at the same time, check whether there is any leakage or other faults in the reactor. If the pressure is too low, it may affect the progress of the reaction. It is necessary to check whether the intake system is normal and adjust the intake volume appropriately.

03.

Abnormal liquid level

When the liquid level is too high, the feeding should be stopped and the liquid drain valve should be opened to discharge the excess liquid. When the liquid level is too low, the reactants need to be replenished in time, but it is necessary to avoid adding too quickly to prevent excessive fluctuations in the liquid level.

04.

Abnormal pH value

According to the reaction requirements, add acid or base in a timely manner to adjust the pH value and restore it to an appropriate range. During the adjustment process, it should be added slowly and the changes in pH value should be closely monitored.
