Introduction

The optimization of the weight of sodium monochloroacetate and the synthesis of carboxymethyl cellulose (CMC) from empty palm oil bunches (Elaeis Guineensis Jack) is a crucial aspect of utilizing agricultural waste and producing high-quality CMC products. The empty palm oil bunches are a significant source of cellulose, which can be converted into CMC through a series of chemical reactions. This study aims to investigate the optimization of the weight of sodium monochloroacetate and the synthesis of CMC from empty palm oil bunches.

Materials and Methods

The first phase of this study involves the isolation of α-cellulose powder from empty palm oil bunches. The α-cellulose powder is then used as the raw material for the synthesis of CMC. The CMC synthesis process involves the addition of α-cellulose to a solution of 40% NaOH and variations in the weight of sodium monochloroacetate (5, 6, 7, 8, and 9 grams). The reaction is carried out at 60 °C with the use of glacial acetic acid to neutralize the pH. The characterization of α-cellulose and CMC is conducted using Fourier Transform Infra-red (FTIR) spectroscopy, while the degree of substitution and viscosity are analyzed using the acid-base titration method and the Otswald viscometer, respectively.

Results and Discussion

The results of FTIR analysis showed the presence of OH group absorption peaks at 3425 cm-1, CO at 1072 cm-1, and C = O at 1573 cm-1, which indicates the presence of the desired chemical structure in CMC. The analysis of the degree of substitution conducted on the variation of the weight of sodium monochloroacetate to α-cellulose produces a ratio of 5: 5, 5: 6, 5: 7, 5: 8, and 5: 9. The optimal result of the CMC synthesis reaction occurs in the addition of 7 grams of sodium monochloroacetate with a reaction time for 3 hours, producing CMC with a substitution degree of 0.84. This degree of substitution shows the potential of CMC produced for use in various applications, including the food industry and daily products.

Further Analysis

Cellulose carboxymethyl (CMC) is one of the cellulose derivatives that has special properties, such as good solubility in water and the ability to increase the viscosity of the solution. CMC is widely used as a thickener, emulsion stabilizer, and binding agent in various products, both in the food, pharmaceutical, and cosmetic industries. Optimizing the condition of CMC synthesis from oil palm empty bunches is important, especially in an effort to utilize large potential agricultural waste.

The use of sodium monochloroacetate as an alkylation agent in CMC synthesis gives useful results, because it can improve the functional nature of cellulose. Setting the weight of sodium monochloroacetate and the right synthesis time is the key to getting the best quality CMC products. With a degree of substitution of 0.84, CMC produced in this study shows the potential to be applied in food products, where strict regulations regarding the safety and efficiency of food additives are the main concern.

Conclusion

The conclusion of this study shows that optimization in CMC synthesis can not only improve product quality, but also contribute to reducing waste through better local resource use. In addition, the results of this study can be the basis for further research to develop CMC products with wider and more sustainable applications.
