Carboxymethyl cellulose
Ọdịdị:ọcha ma ọ bụ mmiri ara ehi ntụ ntụ
Njirimara anụ ahụ: ọ bụ ihe nrụpụta cellulose nwere otu carboxymethyl (-CH2-COOH) jikọtara ya na ụfọdụ hydroxyl otu nke glucopyranose monomers nke mebere ọkpụkpụ azụ cellulose.A na-akpọkwa ya dị ka CMC, Carboxymethyl.Cellulose sodium, sodium nnu nke Caboxy Methyl Cellulose.CMC bụ otu n'ime ihe dị mkpa solube polyelectrolyte.Ọ nwere ike soluble na mmiri, mmanya na-aba n'anya, ethanol, benzene, chloroform na ihe mgbaze ndị ọzọ.Na-eguzogide mmanụ anụmanụ na ihe oriri na-adịghị eme ya site na ọkụ.
