Carboxyl Methyl Cellulose
Carboxy methyl cellulose (CMC) los yog cmc thickener yog cellulose derivative nrog carboxymethyl pawg (-CH2-COOH) khi rau qee pawg hydroxyl ntawm glucopyranose monomers uas ua rau cov pob txha cellulose.Nws yog feem ntau siv raws li nws cov ntsev ntsev, Sodium Carboxymethyl Cellulose.
Nws yog synthesized los ntawm alkali-catalyzed cov tshuaj tiv thaiv ntawm cellulose nrog chloroacetic acid.Cov polar (organic acid) carboxyl pawg ua rau cellulose soluble thiab chemically reactive.Cov khoom ua haujlwm ntawm CMC nyob ntawm seb qhov kev hloov pauv ntawm cov qauv cellulose (piv txwv li, pes tsawg ntawm cov pab pawg hydroxyl tau koom nrog hauv kev hloov cov tshuaj tiv thaiv), nrog rau cov saw ntev ntawm cov qauv cellulose qaum thiab qib ntawm pawg. carboxymethyl substituents.
