	%X The cellulose was extracted from pomelo peel and an
etherification reaction used for converting cellulose to carboxymethyl
cellulose (CMC). The pomelo peel was refluxed with 0.5 M HCl and 1
M NaOH solution at 90°C for 1 h and 2 h, respectively. The cellulose
was bleached with calcium hypochlorite and used as precursor. The
precursor was soaked in mixed solution between isopropyl alcohol and
40%w/v NaOH for 12 h. After that, chloroacetic acid was added and
reacted at 55°C for 6 h. The optimum condition was 5 g of cellulose:
0.25 mole of NaOH : 0.07 mole of ClCH2COOH with 78.00% of yield.
Moreover, the product had 0.54 of degree of substitution (DS).
