Carboxyl methyl cellulose
Carxxy methyl cellulose (cmc) ranei cmc thickener ko te celbolose sellboseds carroxymethyl roopu (-ch2-coho) ki etahi o nga roopu hydroxyl o nga mowhiti glucopyran. He maha tonu te wa e whakamahia ana hei tote konutai, te konutai pouaka pouaka pouaka pouaka.
Kei te waihangahia e te urupare a te alkali-catalyzed o cellulose me te waikawa chloroacetic. Ko te polar (waikawa organic) roopu carboxyl e tuku ana i te sellulose soluple me te maheni. Ko nga taonga e mahi ana i te CMC e whakawhirinaki ana ki te tohu o te hanganga cellulose (ara, e hia o nga roopu hydroxyl kua uru ki te paparanga o te Cellebosemethy.
