by ADMIN 117 views

Introduction

The synthesis of surfactants is a crucial process in the chemical industry, with applications in various fields such as cleaning products, personal care, and pharmaceuticals. Surfactants are molecules that have both hydrophobic and hydrophilic properties, allowing them to interact with both water and oil. In this study, we aim to synthesize 2- (dodesiloxi) 1-propanol through lauril alcohol eternal using propylene oxide as a surfactant material. This process involves the reaction of lauril alcohol with propylene oxide in the presence of a catalyst, resulting in the formation of a surfactant with unique properties.

Materials and Methods

The synthesis of 2- (dodesiloxi) 1-propanol was carried out using lauril alcohol as the main ingredient, which was reacted with propylene oxide in the presence of a catalyst. The molar ratio of lauril alcohol to propylene oxide was varied from 1:1 to 1:5, and the reaction was carried out at temperatures between 150-160 °C for two hours with constant stirring. The resulting product was characterized using structural analysis with FT-IR spectrophotometer, quantitative analysis with gas chromatography (GC), and determination of the HLB (Hydrophile-Lipophile Balance) value and foam height.

Results and Discussion

The results of the eternification reaction show that with an increase in the ratio of alcohol lauril to propylene oxide, the percentage of formation of 2- (dodesiloxi) 1-propanol also increases. The percentage of products obtained respectively was 18.36%; 22.40%; 23.13%; 25.79%; and 42.94%. This indicates that the more propylene oxide is used, the higher the yield of the surfactant.

In addition, the HLB value obtained from each product is 14.26; 13.91; 13.73; 13.69; and 13.36, which shows that the more propylene oxide is used, the smaller HLB value. This indicates that the surfactant produced is more effective, as surfactants with lower HLB values have better ability to reduce surface tension.

The height of the foam formed also increases along with the increase in the ratio of alcohol lauril with propylene oxide, with a height value of consecutive foam is 0; 0.11; 0.17; 0.23; and 0.31. This shows that the surfactant produced is getting better in producing foam.

Characterization of the Reaction Product

The characterization of the reaction product was carried out through structural analysis using the FT-IR spectrophotometer. The results show a significant change in the peak of vibration, especially in wave numbers (ῡ) = 1064 cm-1 widening. This indicates the formation of an ether group in compound 2- (dodesiloxi) 1-propanol. This peak is a strong evidence that the eternification reaction was successfully carried out, indicating a chemical transformation that produces products with new characteristics.

Conclusion

In conclusion, the synthesis of 2- (dodesiloxi) 1-propanol through lauril alcohol eternal using propylene oxide as a surfactant material is a successful process. The results show that the more propylene oxide is used, the higher the yield of the surfactant and the more effective it is in reducing surface tension. This study provides important information about the physical and chemical characteristics of the surfactant produced, which can be a reference for the development of surfactant products in the chemical industry and other applications that require surfactant.

Future Directions

This study provides a foundation for further research on the synthesis of surfactants using lauril alcohol eternal and propylene oxide. Future studies can focus on optimizing the reaction conditions to improve the yield and properties of the surfactant. Additionally, the study of the applications of the surfactant produced in various fields such as cleaning products, personal care, and pharmaceuticals can provide valuable insights into its potential uses.
