Azelic Acid Amination via Reduction with Hydrogen Using Nickel Catalysts: A Comprehensive Review

Introduction

Azelic acid amination reaction is a crucial process in the synthesis of amine compounds, which are widely used in various industries, including pharmaceuticals and chemicals. The process involves the formation of amides, followed by reduction with hydrogen using nickel catalysts. In this article, we will discuss the synthesis and characterization process of compounds, product analysis and validation methods, and the importance of this process in the field of organic chemistry.

The Synthesis and Characterization Process of Compounds

The azelic acid amination reaction is a complex process that involves several stages. The first stage is the formation of amides, which is carried out using pressurized ammonia and nickel catalyst at 180 ° C for 5 hours. The results of the amide obtained are then mixed with calcium oxide (CAO) and aluminum oxide (Al2O3) in a pyrex container, and then heated at 300 ° C for 10 minutes in a vacuum condition. This stage aims to eliminate the remnants of water and produce a more stable structure.

The next stage is the extraction of the amide products using n-hexane, which helps to eliminate unwanted compounds and produce purer products. The reduction stage is the most crucial part of this process, where hydrogen is added at high pressure to convert amides into amines. The importance of temperature and pressure control is very crucial at this stage, as it can affect the reaction efficiency and produce unwanted side products.

The final stage is the characterization of the products produced, which is carried out using spectroscopy techniques such as FT-IR and 1H-NMR. The FT-IR method is used to detect the presence of certain functional groups in the compound produced, while the 1H-NMR provides detailed information about the environment of hydrogen atoms in compounds.

Product Analysis and Validation Methods

The testing of the products produced is carried out using spectroscopy techniques such as FT-IR and 1H-NMR. The FT-IR method is used to detect the presence of certain functional groups in the compound produced, such as the shift in the ribbon in the FT-IR spectrum, which can show changes from amide to nitril and then to amines.

On the other hand, 1H-NMR provides detailed information about the environment of hydrogen atoms in compounds, which helps in identifying final structures. The results of the spectroscopy analysis show that the azelic acid amination reaction is an effective method for producing nonana-1,9-diamina.

Importance of Nickel Catalysts

The selection of nickel catalysts has a key role in increasing reaction efficiency. Nickel catalysts are widely known for their ability to speed up the reduction process, resulting in more optimal results in a relatively short time. The use of nickel catalysts also helps to reduce the reaction time and increase the yield of the desired product.

Conclusion

In conclusion, the process of amination of azelic acid through reduction with hydrogen using nickel catalysts is an effective method for producing nonana-1,9-diamina. By understanding each stage in this process, researchers and practitioners can increase the efficiency and results of the desired amine compound synthesis. Further research on the optimization of the condition of the reaction and utilization of alternative catalysts is also an important step for further development in the field of organic chemistry.

Future Directions

Further research on the optimization of the condition of the reaction and utilization of alternative catalysts is also an important step for further development in the field of organic chemistry. The use of alternative catalysts, such as palladium or platinum, may also be explored to improve the efficiency and yield of the desired product.

Additionally, the use of azelic acid amination reaction in the synthesis of other amine compounds may also be explored. The reaction conditions and catalysts used in this process may be adapted to produce other amine compounds with different functional groups.
