Carboxyl Methyl Cellulose
ʻO ka carboxy methyl cellulose (CMC) a i ʻole ka cmc mānoanoa he mea ia me nā hui carboxymethyl (-CH2-COOH) i hoʻopaʻa ʻia i kekahi o nā pūʻulu hydroxyl o nā monomers glucopyranose i hana i ka iwi kuamoʻo cellulose.Hoʻohana pinepine ʻia e like me kāna paʻakai sodium, Sodium Carboxymethyl Cellulose.
Hoʻopili ʻia ia e ka hopena alkali-catalyzed o cellulose me ka waikawa chloroacetic.Na nā pūʻulu carboxyl polar (organic acid) e hoʻoheheʻe i ka cellulose a hoʻoheheʻe kemika.ʻO nā waiwai hana o CMC e hilinaʻi ʻia ma ke ʻano o ka hoʻololi ʻana o ka hale cellulose (ʻo ia hoʻi, ʻehia ka nui o nā pūʻulu hydroxyl i komo i ka hoʻololi hoʻololi), a me ka lōʻihi o ke kaulahao o ke ʻano iwi kuamoʻo cellulose a me ke degere o ka hui ʻana. nā mea pani carboxymethyl.
