Introduction

The process of esterification of oleic acid with glycerol using a 1,2-dimethyl-1,1,1,2,2-tetrafnelsulfonatodisilana catalyst has been successfully employed to produce monooleilglycerol (MG) and dioleilglycerol (DG). This reaction is a crucial step in the synthesis of these compounds, which have various applications in the food, cosmetics, and pharmaceutical industries. The esterification reaction is carried out in stainless steel autoclaves with variations in the ratio of oleic acid molars to glycerol (2:1, 1:1, and 1:2) and temperatures (120°C and 140°C) for 10 hours. The products produced are then characterized using infrared spectroscopy (FT-IR) and gas chromatography (GC).

The use of a catalyst in the esterification reaction is essential to enhance the reaction rate and selectivity. In this study, the 1,2-dimethyl-1,1,1,2,2-tetrafnelsulfonatodisilana catalyst was used to facilitate the reaction between oleic acid and glycerol. The catalyst plays a crucial role in the esterification reaction by lowering the activation energy required for the reaction to occur.

Results and Discussion

The results of the esterification reaction showed that the molar and temperature ratio had a significant effect on the results of MG and DG synthesis. In the molar ratio of oleic acid to glycerol 2:1 and a temperature of 140°C, MG 3.34% and DG 72.09% were produced. In the molar ratio 1:1 and a temperature of 120°C, MG 5.76% and 70.17% were produced. Whereas in the molar ratio 1:2 and a temperature of 120°C, MG was produced 18.37% and DG 79.78%.

The results indicate that an increase in the molar ratio of glycerol to oleic acid and a decrease in reaction temperature can increase the percentage of MG produced. This can be explained through the mechanism of esterification reactions involving the reaction between oleic acid carboxyl groups and glycerol hydroxyl groups. With a higher glycerol molar ratio, there are more hydroxyl groups available to react with oleic acid, thereby increasing the chances of forming MG. Decreased reaction temperature can also increase selectivity to the formation of MG. Lower temperatures can reduce the rate of secondary esterification reactions that can produce DG.

Analysis

The analysis of the results showed that the esterification reaction is highly dependent on the molar ratio of oleic acid to glycerol and the reaction temperature. The results indicate that an increase in the molar ratio of glycerol to oleic acid and a decrease in reaction temperature can increase the percentage of MG produced. This can be explained through the mechanism of esterification reactions involving the reaction between oleic acid carboxyl groups and glycerol hydroxyl groups.

Conclusion

This study shows that the process of oleic acid esterification with glycerol using a 1,2-dimethyl-1,1,1,2,2-tetrafnelsulfonatodisilana catalyst can produce MG and DG with varying results depending on the molar ratio and reaction temperature. The results obtained can be used as a basis for optimizing the MG and DG synthesis process with higher results.
