Solubility ea sodium carboxymethyl cellulose ka metsing

Selelekela

Carboxymethyl cellulose (CMC) ke mofuta oa derivative ea cellulose e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, pampiri le masela.Ke polymer e qhibilihang ka metsing e hlahisoang ka ho arabela selulose ka sodium monochloroacetate kapa sodium dichloroacetate ka pel'a alkali.CMC ke phofo e tšoeu, e sa nkhang hamonate, e sa latsoeheng e sebelisoang e le ntho e teteaneng, stabilizer, emulsifier le e emisang lihlahisoa tse fapaneng.E boetse e sebelisoa e le se tlamella matlapa le li-capsules, hape e le setlolo ha ho etsoa matlapa.

Ho qhibiliha ha CMC metsing ho ipapisitse le lintlha tse 'maloa, ho kenyelletsa tekanyo ea ho fetola (DS), boima ba limolek'hule, le pH.Tekanyo ea ho nka sebaka ke palo ea lihlopha tsa carboxymethyl ka unit ea anhydroglucose (AGU) ka har'a ketane ea polymer, 'me hangata e hlahisoa e le peresente.Ha DS e phahame, CMC e na le hydrophilic haholoanyane 'me e qhibiliha haholoanyane metsing.Boima ba limolek'hule tsa CMC bo boetse bo ama ho qhibiliha ha eona metsing;boima ba limolek'hule bo phahameng bo atisa ho qhibiliha haholoanyane.Qetellong, pH ea tharollo e ka boela ea ama ho qhibiliha ha CMC;boleng ba pH bo phahameng bo atisa ho eketsa ho qhibiliha ha CMC.

Ho qhibiliha ha CMC metsing ho boetse ho angoa ke boteng ba lintho tse ling ka tharollo.Mohlala, boteng ba li-electrolyte joalo ka sodium chloride bo ka fokotsa ho qhibiliha ha CMC metsing.Ka mokhoa o ts'oanang, boteng ba metsoako ea tlhaho e kang ethanol le eona e ka fokotsa ho qhibiliha ha CMC metsing.

Ho qhibiliha ha CMC metsing ho ka khethoa ka ho lekanya khatello ea CMC ka tharollo ho sebelisa spectrophotometer.Botebo ba CMC ka tharollo bo ka khethoa ka ho lekanya ho monya ha tharollo ka bolelele ba 260 nm.Monyetla o lekana le khatello ea CMC tharollong.

Ka kakaretso, CMC e qhibiliha haholo metsing.The solubility ea CMC ka metsing e eketseha ka tekanyo e ntseng e eketseha ea ho fetola, boima ba limolek'hule, le pH.Ho qhibiliha ha CMC metsing ho boetse ho angoa ke boteng ba lintho tse ling ka tharollo.

Qetello

Carboxymethyl cellulose (CMC) ke polima e qhibilihang ka metsing e sebelisoang haholo liindastering tse fapaneng.The solubility ea CMC metsing itšetlehile ka lintlha tse 'maloa, ho akarelletsa le tekanyo ea ho fetola, boima ba limolek'hule, le pH.Ka kakaretso, CMC e qhibiliha haholo metsing, 'me ho qhibiliha ha eona ho eketseha ka tekanyo e ntseng e eketseha ea sebaka, boima ba limolek'hule le pH.Ho qhibiliha ha CMC metsing ho boetse ho angoa ke boteng ba lintho tse ling ka tharollo.Botebo ba CMC ka tharollo bo ka khethoa ka ho lekanya ho monya ha tharollo ka bolelele ba 260 nm.
