**Synthesis of N-9,10 Dihydroxy Stearil Chitosan Through Chitosan Reaction with Oleil Chloride**

Introduction

The development of environmentally friendly materials has become a pressing concern in recent years, as the world grapples with the consequences of pollution and climate change. In this context, the synthesis of N-9,10 dihydroxy stearil chitosan through a reaction between chitosan and oleil chloride has emerged as a promising area of research. This study aims to explore the synthesis of this compound and its potential applications in various industries.

Background

Chitosan, a natural polymer derived from crustacean skin, has been widely used in various applications due to its biodegradable and non-toxic properties. However, its use is often limited by its poor emulsification capabilities. To address this issue, researchers have been exploring ways to modify chitosan to enhance its emulsification properties. One approach is to react chitosan with oleil chloride, a compound that contains a stearil chain, to produce N-9,10 dihydroxy stearil chitosan.

Synthesis of N-9,10 Dihydroxy Stearil Chitosan

The synthesis of N-9,10 dihydroxy stearil chitosan involves a series of steps, starting with the chlorination of oleic acid using PCl5 to produce oleil chloride. The oleil chloride then reacts with the amino group found in chitosan, producing chitosan oleil. The resulting compound undergoes an epoxidation process, which produces new compounds that are expected to have better properties compared to the initial compounds.

Characterization of N-9,10 Dihydroxy Stearil Chitosan

The characterization of N-9,10 dihydroxy stearil chitosan was carried out using Fourier Transform Infrared Spectroscopy (FT-IR). The results showed that the compound exhibits absorption in wave numbers 902.69 cm⁻¹ and 1404.18 cm⁻¹, indicating the presence of a hydroxyl group (C-OH). The peak intensity of the vibration to the wave numbers above 3400 cm⁻¹ also indicates an increase in the concentration of hydroxyl groups (-OH) after the epoxidation process. Additionally, the vibration peak in the 1712 cm⁻¹ wave number indicates the presence of a carbonyl group (C = O), and in the wave number 725 cm⁻¹ there is a bond (CH₂) ₙ, where n ≥ 4, which shows the presence of the stearil chain.

Determination of Hydrophilic Lipophilic Balance (HLB)

The determination of the HLB value of N-9,10 dihydroxy stearil chitosan was carried out using the titration method, which involves measurement of acid numbers and saponification numbers. The results obtained showed the HLB value of 12.8, indicating that the compound acts as an emulsifier with the Dispersion Oil in Water (O/W) system.

Additional Analysis and Explanation

The results of the synthesis of N-9,10 dihydroxy stearil chitosan are very important in the development of environmentally friendly emulsifiers. Chitosan, which comes from crustacean skin, is a natural polymer that is biodegradable, so that its use in the emulsion industry can reduce the environmental impact produced by synthetic compounds. The existence of a hydroxyl group in this compound enhances the nature of polarity, which provides better emulsification capabilities. This trait is very necessary in various applications, ranging from the food industry to pharmacy.

Conclusion

In conclusion, the synthesis of N-9,10 dihydroxy stearil chitosan through the reaction of chitosan and oleil chloride shows great potential in various industrial applications, as well as making a positive contribution in efforts to develop materials that are more sustainable and environmentally friendly. The compound's ability to act as an emulsifier with the O/W system makes it a promising candidate for use in the formulation of drugs, cosmetics, and other products that require high emulsion stability.

Future Directions

Future research directions include the optimization of the synthesis process to improve the yield and purity of the compound, as well as the exploration of its potential applications in various industries. Additionally, the study of the compound's biodegradability and toxicity is essential to ensure its safe use in various applications.
