Carboxyl Methyl Cellulose
Carboxy methyl cellulose (CMC) ko cmc thickener ne na cellulose samu tare da carboxymethyl kungiyoyin (-CH2-COOH) daure zuwa wasu daga cikin hydroxyl kungiyoyin na glucopyranose monomers cewa hada cellulose kashin baya.Ana amfani da shi azaman gishirin sodium, sodium Carboxymethyl Cellulose.
An haɗa shi ta hanyar alkali-catalyzed dauki na cellulose tare da chloroacetic acid.Ƙungiyar polar (Organic acid) ƙungiyoyin carboxyl suna sa cellulose mai narkewa da amsawa ta hanyar sinadarai.Abubuwan da ke aiki na CMC sun dogara ne akan matakin maye gurbin tsarin cellulose (watau nawa ne ƙungiyoyin hydroxyl suka shiga cikin maye gurbin), da kuma tsawon sarkar tsarin kashin baya na cellulose da matakin tari. Carboxymethyl maye gurbin.
