Synthesis and Characterization of Starch Ether Products Alkoxilated Epoxide Oil Palm Oil with Starch

Introduction

Starch is a versatile and widely used natural polymer that has been extensively modified to produce various starch derivatives with improved functional properties. One of the most common methods of starch modification is the reaction between starch and epoxide of oil palm oil, resulting in the formation of starch ether. In this study, we aimed to synthesize and characterize starch ether products alkoxilated epoxide oil palm oil with starch using various analytical techniques, including FT-IR and SEM spectroscopy.

Analysis of the Functional Cluster Using FT-IR

The analysis of the functional group is a crucial step in the characterization of starch ether. In this study, we used the FT-IR spectrophotometer to analyze the functional group of starch ether. The results of this analysis indicate the presence of the vibration area C = O in the wave number 1743 cm-1, which indicates the formation of ester bonds. This is a significant finding, as the formation of ester bonds is a key characteristic of starch ether. In addition, the emergence of hydrocarbon chain vibrations (CH2) N on the FT-IR spectrum shows that starch has undergone structural modification, which indicates the success of the alkoxilation process.

The FT-IR analysis also revealed the presence of other functional groups, including hydroxyl (-OH) and carbonyl (C=O) groups. These functional groups are responsible for the unique properties of starch ether, including its solubility, viscosity, and reactivity. The presence of these functional groups also indicates that the starch ether has undergone significant structural modification, which is a key characteristic of starch derivatives.

Morphological Characterization with SEM

In addition to the analysis of the functional group, we also used SEM to analyze the surface morphology of starch ether. The observations show that the starch granules have a denser and dense form compared to commercial starch granules. This change indicates a significant interaction between starch and epoxide, which can affect the functional nature of the ether starch.

The SEM analysis also revealed the presence of pores and cavities on the surface of starch ether. These pores and cavities are responsible for the unique properties of starch ether, including its solubility, viscosity, and reactivity. The presence of these pores and cavities also indicates that the starch ether has undergone significant structural modification, which is a key characteristic of starch derivatives.

Determination of the Degree of Substitution

In addition to structural and morphological analysis, this research also determines the degree of substitution of the resulting starch ether. The results show that the degree of substitution reached 77.25%. This figure shows a high level of success in the process of alkoxilation, and has the potential to improve the functional nature of starch ether as an additional material in various applications, including the food and pharmaceutical industry.

The degree of substitution is a critical parameter in the characterization of starch ether. It indicates the extent to which the starch has undergone structural modification, and is responsible for the unique properties of starch ether. A high degree of substitution indicates that the starch ether has undergone significant structural modification, which is a key characteristic of starch derivatives.

Conclusion

The synthesis of the starch ether from the alkoxilation of palm oil olein oil epoxide produces products with different characteristics of commercial starch. The results of FT-IR analysis showed the formation of ester bonds, while SEM observations showed more dense morphology. The high degree of substitution shows the success of its synthesis and potential for broader applications. This research not only expands the understanding of starch modification, but also opens opportunities for the development of more innovative starch-based products.

Future Directions

The results of this study have significant implications for the development of starch-based products. The starch ether produced in this study has unique properties that make it suitable for use in various applications, including the food and pharmaceutical industry. The high degree of substitution and the presence of ester bonds indicate that the starch ether has undergone significant structural modification, which is a key characteristic of starch derivatives.

In the future, we plan to explore the potential of starch ether in various applications, including the development of biodegradable plastics, biocomposites, and biolubricants. We also plan to investigate the effects of different reaction conditions on the properties of starch ether, and to develop new methods for the synthesis of starch ether.

Materials and Methods

The materials used in this study include commercial starch, epoxide of oil palm oil, and various analytical reagents. The synthesis of starch ether was carried out using a two-step process, involving the reaction between starch and epoxide of oil palm oil. The resulting starch ether was then analyzed using various analytical techniques, including FT-IR and SEM spectroscopy.
