Sebopeho sa sodium carboxymethyl cellulose

Selelekela

Carboxymethyl cellulose (CMC) ke mofuta oa derivative ea cellulose e nkiloeng ho cellulose ke carboxymethylation. Ke phofo e tšoeu, e sa nkheng, e sa latsoeheng e sebelisoang haholo lijong, meriana, litlolo le liindasteri tse ling. CMC ke polymer e qhibilihang ka metsing e nang le mefuta e mengata ea ts'ebeliso ka lebaka la thepa ea eona e ikhethang. E sebelisoa e le ntho e tiisang matla, stabilizer, emulsifier le e emisang. CMC e boetse e sebelisoa e le colloid e sireletsang ha ho etsoa pampiri le masela.

Sebopeho

Sebopeho sa carboxymethyl cellulose (CMC) se entsoe ka ketane e lekanang ea limolek'hule tsa tsoekere tse hokahantsoeng ka li-bond tsa glycosidic. Limolek'hule tsa glucose li hokahane ho tse ling ka athomo e le 'ngoe ea oksijene, ho etsa ketane e melang. Ketane ea mela e ntan'o ba carboxymethylated, e bolelang hore sehlopha sa carboxymethyl (CH2COOH) se kopantsoe le sehlopha sa hydroxyl (OH) sa molek'hule ea tsoekere. Ts'ebetso ena ea carboxymethylation e fella ka molek'hule ea carboxymethyl cellulose e qosoang hampe.

Sebopeho sa carboxymethyl cellulose se ka emeloa ke foromo e latelang:

(C6H10O5)n-CH2COOH

moo n ke tekanyo ea ho fetola (DS) ea sehlopha sa carboxymethyl. Tekanyo ea ho nka sebaka ke palo ea lihlopha tsa carboxymethyl ka molek'hule ea tsoekere. Ha tekanyo ea phetisetso e phahame, e phahamisa viscosity ea tharollo ea CMC.

Thepa Carboxymethyl cellulose e na le lisebelisoa tse ngata tse ikhethang tse etsang hore e be molemo lits'ebetsong tse fapaneng. Ke polymer e qhibilihang ka metsing e tsitsitseng haholo mekhoeng ea metsi. Hape ha e na chefo, ha e tenehe ebile ha e na allergenic. CMC e boetse e hanyetsana le ho senyeha ha likokoana-hloko 'me ha e amehe ke pH kapa mocheso. CMC ke setenya se matla 'me se ka sebelisoa ho tenya mefuta e mengata ea lino, ho kenyeletsoa lijo, meriana le litlolo. E boetse e sebelisoa e le emulsifier, stabilizer, le moemeli ea emisang. CMC e boetse e sebelisoa e le colloid e sireletsang ha ho etsoa pampiri le masela. Qetello Carboxymethyl cellulose (CMC) ke mofuta oa derivative ea cellulose e nkiloeng ho cellulose ke carboxymethylation. Ke phofo e tšoeu, e sa nkheng, e sa latsoeheng e sebelisoang haholo lijong, meriana, litlolo le liindasteri tse ling. CMC e entsoe ka letoto la limolek'hule tsa tsoekere tse hokahantsoeng ka libond tsa glycosidic le carboxymethylated. E na le lintho tse ngata tse ikhethang tse etsang hore e be molemo mefuteng e fapaneng ea ts'ebeliso. CMC ke ntho e matla e tiisang matla 'me e ka sebelisoa e le emulsifier, stabilizer, le e emisang.
