Acetyl Rayon Synthesis Through Acetylation With Anhydrid Acetate As A Liquor Or Fiber
Introduction
Acetyl rayon synthesis is a crucial process in the production of cellulose-based materials, which have a wide range of applications in the textile industry. The process involves the acetylation of cellulose using anhydrid acetic acid as a reactant, with the help of concentrated sulfuric acid as a catalyst. In this study, we aim to investigate the synthesis of acetyl rayon through acetylation with anhydrid acetate, both as a liquor and a fiber, and to determine the optimum conditions for the process.
The Acetylation Process
The acetylation process is a crucial step in the synthesis of acetyl rayon. It involves the reaction of cellulose with anhydrid acetic acid in the presence of concentrated sulfuric acid as a catalyst. The process is carried out in two stages: the initial treatment of rayon with glacial acetic acid, followed by the acetylation stage using anhydrid acetic acid. The reaction is carried out at a temperature of 40 ° C, with a stirring time of 6 hours.
Optimum Conditions for Synthesis
The optimum conditions for the synthesis of tri acetyl rayon were determined by varying the temperature and stirring time. The results showed that the optimum temperature for the synthesis of tri acetyl rayon is 40 ° C, with a stirring time of 6 hours. This resulted in a yield of 52%. In contrast, the optimum temperature for the making of liquor is 70 ° C, with the same stirring time, which resulted in a yield of 100%. These results highlight the importance of controlling temperature and time in the synthesis process to achieve the desired results.
Analysis of FT-IR and DTA Spectroscopy
The results of the analysis of FT-IR and DTA spectroscopy showed that not all hydroxyl groups in the cellulose chain are produced. However, the product produced is in the form of a tri acetyl rayon because there is an unsolved residue in the medium of acetylation. The degree of substitution (DS) obtained is 2.92, with an acetyl content reaching 44.09%. This indicates that although the acetylation process does not fully replace the hydroxyl group, the final product still meets the criteria to be categorized as a tri acetyl rayon.
Analysis of Electron Microscope (SEM)
The analysis of the electron microscope (SEM) shows that the tri acetyl rayon still maintains the shape of the fiber. This is important in the context of its use, because the form of fiber is one of the main characteristics that determines the application of rayon in the textile industry. In addition, FT-IR analysis also indicates the existence of ester rayon in liquor, adding evidence that the product produced has broad potential applications both in the form of fiber and liquor.
Conclusion
In conclusion, the process of acetyl rayon synthesis through acetylation with anhydrid acetate not only succeeded in producing tri acetyl rayon but also shows that control of the synthesis conditions is very crucial. This research opens opportunities for further development in the field of cellulose-based material, which can have a significant impact in the textile industry and other applications. Success in achieving high yield and desired material characteristics indicates the potential commercialization of this product in the future.
