Sodium carboxymethyl cellulose solubility a cikin ruwa

Gabatarwa

Carboxymethyl cellulose (CMC) wani nau'i ne na cellulose wanda aka yi amfani dashi sosai a masana'antu daban-daban, ciki har da abinci, magunguna, takarda, da kuma tufafi.Yana da polymer mai narkewa da ruwa wanda aka samar ta hanyar amsa cellulose tare da sodium monochloroacetate ko sodium dichloroacetate a gaban alkali.CMC fari ne, mara wari, foda mara ɗanɗano wanda ake amfani da shi azaman wakili mai kauri, stabilizer, emulsifier, da wakili mai dakatarwa a cikin samfura daban-daban.Hakanan ana amfani dashi azaman ɗaure a cikin allunan da capsules, kuma azaman mai mai a cikin kera allunan.

Solubility na CMC a cikin ruwa ya dogara da abubuwa da yawa, gami da matakin maye gurbin (DS), nauyin kwayoyin halitta, da pH.Matsayin maye gurbin shine adadin ƙungiyoyin carboxymethyl a kowace naúrar anhydroglucose (AGU) a cikin sarkar polymer, kuma yawanci ana bayyana shi azaman kashi.Mafi girma da DS, mafi yawan hydrophilic CMC kuma mafi narkewa yana cikin ruwa.Nauyin kwayoyin CMC kuma yana shafar narkewar ruwa a cikin ruwa;mafi girma kwayoyin nauyi ayan zama mafi soluble.A ƙarshe, pH na maganin kuma zai iya rinjayar solubility na CMC;mafi girma pH dabi'u ayan ƙara solubility na CMC.

Solubility na CMC a cikin ruwa kuma yana shafar kasancewar wasu abubuwa a cikin maganin.Misali, kasancewar electrolytes kamar sodium chloride na iya rage narkewar CMC a cikin ruwa.Hakazalika, kasancewar kwayoyin kaushi irin su ethanol kuma na iya rage narkewar CMC a cikin ruwa.

Ana iya ƙayyade solubility na CMC a cikin ruwa ta hanyar auna ma'auni na CMC a cikin bayani ta amfani da spectrophotometer.Za'a iya ƙayyade ƙaddamarwar CMC a cikin wani bayani ta hanyar auna ma'auni na maganin a tsawon 260 nm.Abin sha yana daidai da ƙaddamarwar CMC a cikin maganin.

Gabaɗaya, CMC yana narkewa sosai a cikin ruwa.Solubility na CMC a cikin ruwa yana ƙaruwa tare da ƙara darajar canji, nauyin kwayoyin halitta, da pH.Solubility na CMC a cikin ruwa kuma yana shafar kasancewar wasu abubuwa a cikin maganin.

Kammalawa

Carboxymethyl cellulose (CMC) polymer ne mai narkewa da ruwa wanda ake amfani dashi sosai a masana'antu daban-daban.Solubility na CMC a cikin ruwa ya dogara da dalilai da yawa, gami da matakin maye gurbin, nauyin kwayoyin halitta, da pH.Gabaɗaya, CMC yana narkewa sosai a cikin ruwa, kuma mai narkewar sa yana ƙaruwa tare da ƙara matakin maye gurbin, nauyin kwayoyin, da pH.Solubility na CMC a cikin ruwa kuma yana shafar kasancewar wasu abubuwa a cikin maganin.Za'a iya ƙayyade ƙaddamarwar CMC a cikin wani bayani ta hanyar auna ma'auni na maganin a tsawon 260 nm.
