Carboxyl Methyl cellulose
Carboxy methyl cellulose (cmc) lossis cmc thickener yog lub cellulose derivative nrog cov pab pawg carboxymethyl ntawm glucopyranose monomers uas ua rau lub cellulose cellebone. Nws feem ntau siv los ua nws cov ntsev ntsev, sodium carboxymethyl cellulose.
Nws yog synthesized los ntawm cov alkali-catalyzed tshuaj tiv thaiv ntawm cellulose nrog chloroacetic acid. Cov Ncauj Qaum (organic acid) Carboxyl pab pawg render lub cellulose soluble thiab chemically reactive. Lub zog ua haujlwm ntawm CMC yog nyob ntawm cov qib ntawm cov qauv cellulose (piv txwv li cov qauv ntawm cov cellulose ntawm cov kab mob cellulose thiab cov qib ntawm pawg ntawm cov carboxymethyl hloov chaw.
