Introduction

Fat alcohol sulfation is a crucial process in the production of surfactants and other industrial chemicals. The process involves the reaction of fat alcohols with sulfur trioxide (SO3) in the presence of dimethylformamide (DMF) to produce sulfated compounds. In this study, we investigated the use of the SO3-DMF complex in fat alcohol sulfation with various carbon chain comparisons. The goal was to understand the relationship between the length of the carbon chain and the results of sulfation, as well as the importance of the tensioactive nature of the product produced.

Preparation of the SO3-DMF Complex

The first step in the process was the preparation of the SO3-DMF complex. This was achieved by reacting SO3 gas with DMF at a temperature of 0-4 °C for three hours. The complex was then formed and used in the sulfation process.

Sulfation Process

The sulfation process was carried out at a temperature of 100 °C for five hours in fat alcohols with carbon chains C8, C10, C16, and C18. The results of the sulfation process showed that the yield obtained was 83%, 81%, 68%, and 61% for each carbon chain, respectively.

Analysis of Sulfation Results

Further analysis was carried out using the Du Nouy method to determine the tensioactive nature of the sulfation products. The analysis results showed a variety of values: 35.3 dyne/cm for C8, 30.3 dyne/cm for C10, 29.4 dyne/cm for C16, and 33.6 dyne/cm for C18. In addition, foam stability was also tested and showed interesting variations with a value of 0.2 cm for C8, 0.8 cm for C10, 0.7 cm for C16, and 1 cm for C18.

Discussion

The results obtained from the sulfation process and analysis showed that the shorter carbon chain (C8 and C10) gave better results in terms of yield of sulfation and tensioactive properties. This may be caused by a simpler molecular structure, which allows the sulfation reaction to take place more efficiently. Conversely, in a longer carbon chain (C16 and C18), both yield and tensioactive properties tended to decrease. This shows the steric resistance that can affect the sulfation reaction.

Impact on Applications

Fat alcohol sulfation products have many applications in the industry, including in the manufacture of detergents, cosmetics, and emulsions. Therefore, the selection of the right carbon chain is very important to achieve the desired physical properties of the final product. Surfactant with good tensioactive properties will have a higher ability to reduce water surface tension, which is essential in various industrial applications.

Conclusion

The process of fat alcohol sulfation using the SO3-DMF complex offers the potential to produce high-quality surfactants. This study not only shows the relationship between the length of the carbon chain and the results of sulfation, but also the importance of the tensioactive nature of the product produced. Through optimizing this process, it is hoped that new products can be developed that are more efficient and environmentally friendly.

Future Directions

With a deep understanding of this process, industrial researchers and practitioners can design applications that are more innovative and efficient in the use of alcohol fat sulfation in various fields. Further research is needed to explore the potential of this process in the production of surfactants and other industrial chemicals.
