Carboxyl Methyl Cellulose
Carboxy methyl cellulose (CMC) ama cmc thickener waa soosaar cellulose leh kooxaha carboxymethyl (-CH2-COOH) oo ku xidhan qaar ka mid ah kooxaha hydroxyl ee monomers glucopyranose ee ka kooban laf dhabarta cellulose.Waxaa inta badan loo isticmaalaa sida milixdeeda sodium, Sodium Carboxymethyl Cellulose.
Waxaa lagu farsameeyaa falcelinta alkali-catalyzed ee cellulose leh chloroacetic acid.Polar (Organic acid) kooxaha karboksylku waxay keenaan cellulose mid milmaya oo kiimiko ahaan falceliya.Sifooyinka shaqeynaya ee CMC waxay ku xiran yihiin heerka beddelka qaab dhismeedka cellulose (ie, intee in le'eg oo ka mid ah kooxaha hydroxyl ayaa ka qayb qaatay falcelinta beddelka), iyo sidoo kale dhererka silsiladda qaab dhismeedka laf dhabarta cellulose iyo heerka ururinta beddelka karboxymethyl.
