Carboxyl Methyl Cellulose
Ko te Carboxy methyl cellulose (CMC) ko te cmc thickener he whakaputanga cellulose me nga roopu carboxymethyl (-CH2-COOH) kua herea ki etahi o nga roopu hydroxyl o nga monomers glucopyranose e hanga ana i te tuara cellulose.He maha nga wa e whakamahia ana hei tote konutai, Sodium Carboxymethyl Cellulose.
Ka whakahiatohia e te tauhohenga alkali-catalyzed o te cellulose me te waikawa chloroacetic.Ko nga roopu carboxyl polar (waikawa waro) ka huri te cellulose ki te wairewa me te hohenga matū.Ko nga ahuatanga mahi o te CMC e whakawhirinaki ana ki te tohu o te whakakapinga o te hanganga cellulose (ara, e hia o nga roopu hydroxyl i whai waahi ki te tauhohenga whakakapi), tae atu ki te roa o te mekameka o te hanganga tuara cellulose me te tohu o te rapoi o nga mea whakakapi carboxymethyl.
