Sodium carboxymethyl cellulose solubility mumvura

Nhanganyaya

Carboxymethyl cellulose (CMC) imhando ye cellulose derivative iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira chikafu, mishonga, mapepa, uye machira. Iyo polymer inonyungudika mumvura inogadzirwa nekuita selulosi ne sodium monochloroacetate kana sodium dichloroacetate pamberi pe alkali. CMC ichena, isinganhuwi, hupfu husina kunaka hunoshandiswa sechinhu chakakora, stabilizer, emulsifier, uye kumisa mumiriri mune zvigadzirwa zvakasiyana. Inoshandiswawo sebhainda mumapiritsi uye capsules, uye semafuta mukugadzirwa kwemapiritsi.

Kunyungudika kweCMC mumvura kunoenderana nezvakati wandei, kusanganisira dhigirii rekutsiva (DS), uremu hwemamorekuru, uye pH. Iyo dhigirii yekutsiva ndiyo nhamba yemapoka ecarboxymethyl pane anhydroglucose unit (AGU) mu polymer cheni, uye inowanzo ratidzwa sechikamu. Iyo yakakwirira yeDS, iyo inowedzera hydrophilic iyo CMC uye yakanyanya kunyungudika iri mumvura. Iyo molecular uremu hweCMC inokanganisawo kunyungudika kwayo mumvura; huremu hwemamorekuru hwepamusoro hunowanzoita soluble zvakanyanya. Chekupedzisira, iyo pH yemhinduro inogona zvakare kukanganisa kunyungudika kweCMC; yakakwirira pH maitiro anowedzera kuwedzera kunyungudika kweCMC.

Kunyungudika kweCMC mumvura kunokanganisawo nekuvapo kwezvimwe zvinhu mumhinduro. Semuenzaniso, kuvepo kwema electrolyte akadai sodium chloride kunogona kuderedza kunyungudika kweCMC mumvura. Saizvozvo, kuvapo kweorganic solvents senge ethanol kunogona zvakare kuderedza kunyungudika kweCMC mumvura.

Kunyungudika kweCMC mumvura kunogona kutariswa nekuyera huwandu hweCMC mune mhinduro uchishandisa spectrophotometer. Iko kusungirirwa kweCMC mune mhinduro inogona kutariswa nekuyera kunyura kwemhinduro pane wavelength ye260 nm. Iyo yekunyudza inoenderana nekusangana kweCMC mune mhinduro.

Kazhinji, CMC inonyanya kunyungudika mumvura. Kunyungudika kweCMC mumvura kunowedzera nekuwedzera dhigirii rekutsiva, uremu hwemamorekuru, uye pH. Kunyungudika kweCMC mumvura kunokanganisawo nekuvapo kwezvimwe zvinhu mumhinduro.

Mhedziso

Carboxymethyl cellulose (CMC) i polymer inonyungudika nemvura iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana. Kunyungudika kweCMC mumvura kunoenderana nezvakati wandei, kusanganisira dhigirii rekutsiva, huremu hwemamorekuru, uye pH. Kazhinji, CMC inonyanya kunyungudika mumvura, uye kunyungudika kwayo kunowedzera nekuwedzera dhigirii rekutsiva, uremu hwemamorekuru, uye pH. Kunyungudika kweCMC mumvura kunokanganisawo nekuvapo kwezvimwe zvinhu mumhinduro. Iko kusungirirwa kweCMC mune mhinduro inogona kutariswa nekuyera kunyura kwemhinduro pane wavelength ye260 nm.
