Organic solvent purification system, also known as solvent purification system, is a device used to improve the purity of organic solvents. It removes water, oxygen and other impurities from solvents through a series of physical and chemical processes. The following are the working principles and applicable solvent types of organic solvent purification systems:
Organic solvent purification system/Working principle of solvent purification system:
1. Low pressure purification technology:
The organic solvent purification system/solvent purification system adopts low-pressure purification technology to ensure the safety and stability of the solvent during the purification process. The low-pressure environment reduces the volatilization of solvents, thereby reducing the risk of fire and explosion, while also protecting the safety of operators.
2. Inert gas protection mechanism:
By using inert gases such as nitrogen or argon to press the solvent from the reservoir into the purification column, the organic solvent purification system/solvent purification system ensures that the solvent does not react with oxygen and moisture in the air during the transfer process. This protective mechanism is crucial as it prevents oxidation and hydrolysis of the solvent, maintaining its chemical stability and purity.
3. Deep deoxygenation process:
When the solvent passes through the deaerator, the oxygen in it comes into contact with the deaerator (usually copper or other metal oxide catalysts), undergoes a chemical reaction, generates stable metal oxides, and thus achieves deep deoxidation.
4. Efficient adsorption purification:
The deoxygenated solvent enters the adsorber containing activated aluminum or other highly efficient adsorbents. These adsorbents can capture moisture and other substances (such as sulfides and acidic substances) in the solvent, thereby further purifying the solvent. This step is crucial to ensure that the solvent does not introduce impurities during subsequent use.
5. Continuous supply of high-purity solvents:
The design of organic solvent purification system/solvent purification system allows for continuous supply of high-purity organic solvents, which is particularly important for experiments and industrial production processes that require long-term operation. Continuous supply ensures the continuity of experiments and production stability, while also reducing time and cost losses caused by solvent replacement.
6. Safe operation design:
The design of organic solvent purification system/solvent purification system fully considers the safety of operation. It avoids the use of heated distilled sodium blocks for water removal or special reagents, which may pose safety risks in traditional solvent purification processes.
Organic solvent purification system/solvent purification system is suitable for various organic solvents, including but not limited to:
1. Hydrocarbon solvents: such as n-hexane, cyclohexane, heptane, etc.
2. Halogenated hydrocarbons: such as dichloromethane, chloroform, bromoethane, etc.
3. Alcohols: such as methanol, ethanol, isopropanol, etc.
4. Ketones: such as acetone, butanone, cyclohexanone, etc.
5. Esters: such as ethyl acetate, butyl acetate, etc.
6. Ethers: such as ether, tetrahydrofuran, etc.
7. Aromatic hydrocarbons: such as benzene, toluene, xylene, etc.
8. Polar solvents: such as dimethyl sulfoxide (DMSO), dimethylformamide (DMF), etc.
9. Other special solvents: such as pyridine, quinoline, etc.
These solvents are widely used in fields such as chemical synthesis, analytical chemistry, drug preparation and materials science, with high purity requirements. Organic solvent purification systems/solvent purification systems can provide high-purity solvents that meet these application requirements while ensuring operational safety and efficiency.
