In this study, the synthesis of carboxymethyl cellulose (CMC) from nonusable invasive weed Senna didymobotrya was possible through response surface methodology (RSM)–guided alkalization and etherification methods. The RSM method indicates that maximum CMC yield obtained, 0.85 gm or 85.6%, achieved when 1 6 mol anhydrous glucose unit (AGU) reacted with 3.24 KOH/AGU 1.1 2.05 monochloroacetic acid (MCA)/AGU at 60°C a total reaction time 2 h. This finding opens new avenue for saving chemicals while producing industrial chemicals. analysis also significant valid. is because factors factor interactions used in were ( p < 0.05) precise adequate precision (30.7) found much higher than expected value 4. alkalization, etherification, temperature. degree substitution synthesized 2.5 comparable commercial (2.9). viscosity measurement both materials showed non‐Newtonian pseudoplastic behavior. 331.64 cP 227.08 cP. more viscous CMC.
