Synthesis and Characterization of High-Purity Food Grade Carboxymethyl Celluloses from Different Parts of Maize Waste
Preparation of carboxymethylcellulose: Preparation of CMC sample consists of two reactions which are alkalization and carboxymethylation reaction. Alkalization reaction begins after introduction of NaOH into 10 g of pure cellulose and mixing of ethanol and isopropanol solution under mechanical stirring for an hour. Then, carboxymethylation reaction start once the sodium monochloroacetate (SMCA) is added while the reaction continuously stirs at 400 rpm. Reaction temperature and reaction time are controlled in this reaction. The mixture then filtered and suspended in 200 mL of methanol overnight.

Williamson etherification is mostly applied in industries due to its low toxicity, wide availability, easy handling and its economic efficiency. Carboxymethyl cellulose or CMC is modified cellulose which is prepared by etherification of the hydroxyl groups with sodium monochloroacetate (SMCA) in the presence of aqueous alkali (). CMC is important for its water soluble properties where vast applications are applied in food industry, cosmetics, pharmaceuticals, detergents, textiles, paper, drugs and as well as oil well drilling operation. The conversion of cellulose to carboxymethyl cellulose provides variety of usage due to its excellent characteristics. Among categories of applications of CMC that are in dissolved and dispersed forms are water binder, adhesives, film former, wet tact, binder, suspending aid and thickener ().
