Karakterisasi Kimia CMC (Carboxymethyl Cellulose) Umbi Ganyong

Carboxymethyl Cellulose (CMC) a compound made from starch of tubers ganyong flour with added methanol, propanol and water. Four process involving alkalization process, karboksimetilasi, neutralization in the making CMC. Carboxymethylization alkazation proess Alkazation is reaction between cellulose soda solution (alkaline) to become alkaline (cellulose soluble solution). rection sodium chloro acetate form (Na.CMC) which froms viscous solution. Neutralization last prcess manufacture Two processes were first by reacting 22 g NaOH 20 ClCH2COONa respectively. Acetic acid used during heating oven. The overall results for each degree substitution; pH; viscosity; water content; NaCl concentration; purity; Redemen cellulose: Rendemen CMC ganyong; 0.81; 8; 7 cP; 5% 2.01%; 97.99%; 2%; 98.5% research that has been tested FTIR spectra test can be seen picture there are similarities peaks appears indicating canna generated this study have same chemical molecules commercially food codex at 732 cm-1 while peak commercial 725 carboxyl group -CH. Based on obtained, it concluded good quality as filler make bond stronger.
