Kardanil Methyl Ether Synthesis: Optimization of Cardanol Echery Reaction Time from Cashew Seed Skin

Introduction

The increasing demand for sustainable and eco-friendly industrial raw materials has led to the exploration of natural resources as potential alternatives. One such resource is the cashew seed skin (Anacardium occidentale L.), which contains cardanol, a valuable compound with a wide range of applications. In this study, we investigate the synthesis of kardanil methyl ether through cardanol echery reactions with methyl iodide, with a focus on optimizing the reflux time to maximize the yield of the desired product.

Cardanol Isolation from Cashew Seed Skin

Cardanol is isolated from cashew seed skin through a series of steps involving the addition of acetone, Ca(OH)2, 25% NH4OH, N-Hexane: Ethyl acetate (98: 2), washing with 2.5% NaOH, 5% HCl, distilled water, and finally adding Na2SO4 anhydrrate. The resulting cardanol has a yield of 74.39 g (74.39% of the initial weight of CNSL) with characteristics including a molecular weight of 1,2863 mgkoh/g, iodine number 215.6535 G I2/100 g, viscosity 38.7 CP, density 0.8266 g/m, and pH 6.14.

Kardanil Methyl Ether Synthesis

Kardanil methyl ether synthesis is carried out through etherification reactions between cardanol and methyl iodide in the presence of K2CO3 and acetone. The reaction is conducted under reflux conditions for varying times (7 hours, 8 hours, and 9 hours) to examine the effect of reflux time on the yield of kardanil methyl ether. The results show that the maximum yield of kardanil methyl ether is obtained at a reflux time of 8 hours, with a yield of 12,084 g.

Characterization of Cardanol and Kardanil Methyl Ether

The isolated cardanol and kardanil methyl ether are characterized using FT-IR and GC-MS spectrophotometers. FT-IR analysis reveals the formation of cardanil and cardanil methyl ether, marked by the difference in the peak of the C-O group stretch and vibrations of the C-O-C group in the wave number 1300-1000 cm-1. GC-MS analysis shows the proportion of cardanol obtained at 63.28%, while the proportion of cardanil methyl ether with variations of reflux time (7 hours, 8 hours, and 9 hours) obtained 30.18%, 30.29%, and 22.09% respectively.

Optimization of Reflux Time

The results of the analysis show that the maximum methyl ether cardanil proportion is obtained in the condition of the molar of cardanol: methyl iodide (1: 3), K2CO3 17.3 g, acetone 50 ml, with a reflux time of 8 hours. This study demonstrates that the reflux time has a significant effect on the results of cardanil methyl ether synthesis, and an optimal reflux time of 8 hours is required to produce maximum methyl ether proportion.

Conclusion

This study provides important information for the optimization of the cardanil methyl ether synthesis process by utilizing natural resources, namely cashew seed skin. The results show that the reflux time has a significant effect on the yield of kardanil methyl ether, and an optimal reflux time of 8 hours is required to produce maximum methyl ether proportion. The development of cardanil methyl ether synthesis with optimal reflux time can increase the efficiency of the production process and provide added value to the utilization of cashew seed skin as a source of industrial raw materials.

Future Directions

The findings of this study can be applied to the development of new industrial processes that utilize natural resources as raw materials. Further research is needed to explore the potential applications of kardanil methyl ether in various industries, such as the production of resins, lubricants, and additives. Additionally, the optimization of the cardanil methyl ether synthesis process can be further improved by investigating the effects of other reaction conditions, such as temperature and pressure.
