"Sugarcane leaves are an abundant agricultural waste with the potential for use as a source of cellulose. Cellulose from sugarcane leaves was converted to carboxymethyl cellulose (CMC) by carboxymethylation using sodium hydroxide and monochloroacetic acid in isopropyl alcohol. The yield of CMC was 212.16%. A degree of substitution (DS) equivalent to 0.79 was obtained during the conversion, indicating that the product was water-soluble. Fourier transform infrared (FT-IR) spectroscopy confirmed

Melting temperature (Tm) and degradation temperature (Td) of the sample were 116.6 °C and 270.4 °C, respectively, while the residual mass of 36.49% at 800 °C indicated the presence of a non-volatile component fraction. CMC morphology showed a non-circular form with small particles. Results indicated the potential of sugarcane leaves for production of commercial grade CMC."
