Carboxyl Methyl Cellulose
Carboxy methyl cellulose (CMC) ma ọ bụ cmc thickener bụ mkpụrụ ndụ cellulose nwere otu carboxymethyl (-CH2-COOH) jikọtara na ụfọdụ hydroxyl otu nke glucopyranose monomers nke mebere ọkpụkpụ azụ cellulose.A na-ejikarị ya eme ihe dị ka nnu sodium ya, sodium Carboxymethyl Cellulose.
A na-emepụta ya site na mmeghachi omume alkali-catalyzed nke cellulose na chloroacetic acid.Otu polar (organic acid) nke carboxyl na-eme ka cellulose soluble na kemịkalụ na-emeghachi omume.Njirimara arụ ọrụ nke CMC na-adabere n'ókè nke nnọchi nke usoro cellulose (ya bụ, ole n'ime otu hydroxyl esonyela na mmeghachi omume ngbanwe), yana ogologo ogologo nke ọkpụkpụ azụ cellulose na ogo nke nchịkọta. ndị nnọchi anya carboxymethyl.
