Carboxyl Methyl Cellulose
I-Carboxy methyl cellulose (CMC) okanye i-cmc thickener yi-cellulose derivative enamaqela e-carboxymethyl (-CH2-COOH) ebotshelelwe kwamanye amaqela e-hydroxyl e-glucopyranose monomers enza i-cellulose backbone.Ihlala isetyenziswa njengetyuwa yesodium, iSodium Carboxymethyl Cellulose.
Yenziwa yi-alkali-catalyzed reaction of cellulose kunye ne-chloroacetic acid.Amaqela e-polar (organic acid) e-carboxyl anika i-cellulose ukunyibilika kunye nokusebenza kweekhemikhali.Iimpawu ezisebenzayo ze-CMC zixhomekeke kwiqondo lokutshintshwa kwesakhiwo se-cellulose (oko kukuthi, mangaphi amaqela e-hydroxyl athathe inxaxheba ekuphenduleni ukutshintshwa), kunye nobude bekhonkco lesakhiwo se-cellulose backbone kunye neqondo lokuhlanganisana. izinto ezithatha indawo ye-carboxymethyl.
