Carboxyl Methyl cellulose
Carboxy methyl cellulose (CMC) kapena cmc thickener ndi chochokera ku cellulose yokhala ndi magulu a carboxymethyl (-CH2-COOH) omangika kumagulu ena a hydroxyl a glucopyranose monomers omwe amapanga cellulose msana.Nthawi zambiri amagwiritsidwa ntchito ngati mchere wake wa sodium, Sodium Carboxymethyl cellulose.
Amapangidwa ndi alkali-catalyzed reaction ya cellulose ndi chloroacetic acid.Magulu a polar (organic acid) a carboxyl amapangitsa cellulose kusungunuka komanso kuchitapo kanthu.Zomwe zimagwira ntchito za CMC zimadalira kuchuluka kwa m'malo mwa cellulose (mwachitsanzo, ndi magulu angati a hydroxyl omwe adatengapo gawo pakulowa m'malo), komanso kutalika kwa unyolo wa cellulose msana ndi kuchuluka kwa masango. zotsalira za carboxymethyl.
