Physicochemical Properties ea Alkyl Polyglycosides-Phase boitšoaro
Mekhoa ea binary
Ts'ebetso e ntle haholo ea li-surfactants e hlile e bakoa ke litlamorao tse ikhethang tsa 'mele le lik'hemik'hale. Sena se sebetsa ka lehlakoreng le leng ho thepa ea sebopeho le ka lehlakoreng le leng ho boitšoaro ka tharollo, joalo ka boitšoaro ba mohato. Ha ho bapisoa le li-ethoxylates tsa joala tse mafura (alkyl polyglycol ethers), likarolo tsa physicochemical tsa alkyl glycosides ha li ithutoe hanyane ho fihlela joale. Lithutong tsena, li-alkyl polyglycosides li fumanoe li na le thepa ea bohlokoa eo, maemong a mang, e fapaneng haholo le li-surfactants tse ling tseo e seng tsa ionic. Liphetho tse fumanoeng ho fihlela joale li akaretsoa ka tsela e latelang. Liphapang tse kholo tse amanang le boitšoaro ba li-ethoxylate tsa joala tse mafura li ne li hlolla ka ho khetheha.
Ha ho bapisoa le liphuputso tse hlophisitsoeng tsa ethoxylates ea joala e mafura, ho fihlela joale ke lithuto tse 'maloa tse amanang le lintho tse fapaneng tsa bohloeki tse entsoeng molemong oa boitšoaro ba alkyl Polyglycosides. Ha ho bapisoa liphetho tse fumanoeng, ke habohlokoa ho hopola hore Boteng ba likarolo tsa bobeli bo na le tšusumetso e kholo lintlheng tsa litšoantšo tsa mekhahlelo. Leha ho le joalo, litebello tsa mantlha li ka etsoa mabapi le boits'oaro ba karolo ea alkyl glycosides.Boitšoaro ba mohato oa tekheniki ea C8-10 Alkyl polyglycoside(C8-10 APG) e bontšitsoe ho (Figure1). Lithempereicharang tse kaholimo ho 20 ℃, C8-10 APG e bonahala e le matšoenyehong a phahameng haholo karolong ea isotropic eo viscosity ea eona e eketsehang haholo. Karolo ea birefringent lyotropic ea nematic texture e thehoa hoo e ka bang 95% ka boima ba 'mele, e fetohang hoo e ka bang 98% ka boima ba' mele sebakeng se koahetsoeng ke leru la mekhahlelo e 'meli ea mokelikeli le alkyl polyglycoside e tiileng. Ka mocheso o batlang o le tlase, karolo ea lamellar liquid crystalline e boetse e bonoa pakeng tsa 75 le 85% ka boima ba 'mele.
Bakeng sa ketane e khuts'oane e hloekileng ea n-octyl-β-D-glucoside, setšoantšo sa mohato se ile sa hlahlojoa ka ho qaqileng ke Nilsson et al. le Sakya et al. mekhahlelo ea motho ka mong e ne e tsebahala haholo ka Mekhoa e joalo ka NMR le ho hasanya ha X-ray e nyane (SAXS). Setšoantšo sa 2 se bontša tatellano ea mekhahlelo. Ka mocheso o tlase, hexagonal, cubic mme qetellong karolo ea lamellar e bonoa ka litaba tse ntseng li eketseha tsa surfactant. Phapang mabapi le Setšoantšo sa C8-10 alkyl polyglycoside phase (setšoantšo sa 1) se ka hlalosoa ka phapang ea bolelele ba ketane ea alkyl le ka Palo e fapaneng ea likarolo tsa tsoekere molek'huleng (sheba ka tlase).
