Abstract

The aim of this study was to synthesize and characterize carboxymethyl

cellulose (CMC) from Phoenix dactylifera L. )date palm( leaves by

etherification reaction using sodium mono chloroacetic acid (MCAA) and

sodium hydroxide. The optimum reaction parameters were found to be 55

⁰C, 30% sodium concentration, 3g MCAA/1g cellulose and 4 hours reaction

time to give 0.77 as the highest degree of substitution (DS). FTIR shows that

successful isolation of cellulose and the synthesized CMC has shown the

characteristic peaks at 1726, 1602 and 1419 cm-1 that are attributed to carboxymethyl substituent. The CMC product is water soluble.
