Karakterisasi Karboksimetil Selulosa (CMC) dari Eceng Gondok (Eichornia crassipes (Mart) Solms)
ABSTRACT: Carboxy Methyl
Cellulose (CMC), a compound made made of eceng gondok has been implied for its
characteristic by a constructive wet system, with media such as methanol,
propanol and water. Four consecutive phases involving alkalization,
carboxymethylization, neutralization and drainage were used in the making
process of CMC. The first two process were prepared by reacting NaOH and
ClCH2COONa with NaOH 22; 32.5; 39.2; 45.9 g and 20; 26; 32; 38 g ClCH2COONa
respectively. Added acetic acid was used in the neutralization process, whilst
drainage only involved heating in the oven. The overall result for each
characteristic substitution degree, acidity; viscosity; contens of water
consentration of NaCl and purity 0.4 - 0.85, 6.10 - 8.49, 3 - 10 cP, 3.57 -
19.4 %, 12.9 - 22.4 % and 77.96 - 87.09 % respectively. Based on the obtained
characteristic, could be concluded that CMC is considered as a technical
quality and can also be used as filler constituent in adhesive.
