Synthesis of Chitosan N-Maleoil through the Amidation Reaction between Chitosan and Maleate Anhydride

Introduction

The synthesis of chitosan N-Maleoil through the amidation reaction between chitosan and maleate anhydride has been a topic of interest in recent years due to its potential applications in various fields, including pharmacy and biomedical. Chitosan, a biodegradable and non-toxic polysaccharide, has been widely used in various applications, including drug delivery, tissue engineering, and wound healing. However, its hydrophilic nature can limit its applications in certain fields. The introduction of maleate anhydride into chitosan can modify its properties, making it more suitable for various applications.

Synthesis of N-Maleoil Chitosan

The synthesis of N-Maleoil chitosan involves the amidation reaction between chitosan and maleate anhydride. In this study, 6 grams of chitosan was reacted with 1.6 grams of maleate anhydride in the presence of solvents such as acetic acid 2%, methanol, and n, n-dimethylliformamide (DMF) with stirring for 20 hours at room temperature. After the reaction process was complete, the solvent was removed using a vacuum filtration followed by washing using ethanol, which produced 7.3 grams of chitosan N-Maleoil.

Analysis of N-Maleoil Chitosan Synthesis

The N-Maleoil Chitosan synthesis process involves two main analysis techniques, namely FT-IR (Fouirier Transform Infrared Spectroscopy) and 1H NMR (Proton Nuclear Magnetic Resonance). Both of these methods are important to confirm the success of synthesis and determine the chemical characteristics of the products produced.

FT-IR Analysis

FT-IR analysis is a technique used to identify the existence of a typical functional group for N-Maleoil chitosan. Through FT-IR analysis, researchers can identify the presence of amid bonds, which is a characteristic of N-Maleoil chitosan. The absorption bands at certain wavelengths indicate the presence of amid bonds, which is an important information to confirm the success of synthesis.

1H NMR Analysis

1H NMR analysis provides more detailed information about the chemical environment of protons in molecules. With this analysis, the degree of substitution can also be determined, which in this case reaches 42.17%. This degree of substitution shows the proportion of maleoil groups that are bound to chitosan, which can affect the functional nature of the resulting N-Maleoil chitosan.

HLB Value

The HLB value (hydrophilic-lipophilic balance) obtained is 11 is also important information. This value illustrates the hydrophobic and hydrophilic balance of modified chitosan. With HLB of 11, N-Maleoil chitosan tends to be more hydrophilic, which is very useful in biomedical applications and drug formulations.

Benefits of N-Maleoil Chitosan

N-Maleoil chitosan produced has a variety of potential applications, especially in the fields of pharmacy and biomedical. The nature of its hydrophilik is better than pure chitosan allows N-Maleoil chitosan to be used as a matrix for drug delivery, nutritional carriers, or materials for the development of controlled drug liberation systems.

Applications in Pharmacy and Biomedical

N-Maleoil chitosan can be used as a matrix for drug delivery, nutritional carriers, or materials for the development of controlled drug liberation systems. Its hydrophilic nature makes it suitable for biomedical applications, such as wound healing, tissue engineering, and drug delivery.
