Physicochemical Properties yeAlkyl Polyglycosides-Phase maitiro
Binary systems
Kuita kwakanaka kwema surfactants kunonyanya kukonzerwa nemhedzisiro yemuviri uye kemikari. Izvi zvinoshanda kune rimwe divi kune interface zvivakwa uye kune rimwe divi kune maitiro mune mhinduro, senge chikamu maitiro. Kuenzaniswa nemafuta edoro ethoxylates (alkyl polyglycol ethers), iyo physicochemical parameters yealkyl glycosides yakambodzidzwa zvishoma kusvika zvino. Mune zvidzidzo izvi, alkyl polyglycosides yakawanikwa iine zvinhu zvakakosha izvo, mune dzimwe nguva, zvakasiyana zvakanyanya kubva kune vamwe vasiri-ionic surfactants. Migumisiro yakawanikwa kusvika ikozvino inopfupiswa sezvinotevera. Misiyano yakakosha yakabatana nemafambiro emafuta edoro ethoxylates yainyanya kushamisa.
Zvichienzaniswa nezvidzidzo zvakarongeka zvemafuta edoro ethoxylates, kusvika ikozvino zvidzidzo zvishomanana Zvinosanganisira zvinhu zvekuchena kwakasiyana zvakaitwa muchikamu chemaitiro ealkyl Polyglycosides. Kana uchienzanisa migumisiro yakawanikwa, zvakakosha kuyeuka kuti Kuvapo kwezvikamu zvechipiri kune simba guru pane zvinyorwa zvezvikamu zvezvikamu. Zvakadaro, zvakango cherechedzwa zvinogona kuitwa nezve chikamu hunhu hwealkyl glycosides.Mafambiro echikamu chehunyanzvi C8-10 Alkyl polyglycoside(C8-10 APG) inoratidzwa mu (Mufananidzo1). Pane tembiricha iri pamusoro pe20 ℃, iyo C8-10 APG inoratidzika kusvika kune yakanyanya kunetseka muchikamu cheisotropic icho viscosity inowedzera zvakanyanya. A birefringent lyotropic phase ye nematic texture inoumbwa inosvika 95% nehuremu, iyo inoshanduka inosvika 98% nehuremu kuita makore ane zvikamu zviviri zvemvura uye yakasimba alkyl polyglycoside. Pakudziya kwakadzikira, lamellar liquid crystalline phase inoonekwa zvakare pakati pe75 ne85% nehuremu.
Kune yakachena pfupi-cheni n-octyl-β-D-glucoside, chikamu dhayagiramu yakaongororwa zvakadzama naNilsson et al. uye Sakya et al. zvikamu zvega zvega zvakanyatsoratidzwa neNzira dzakadai seNMR uye duku angle X-ray scattering (SAXS). Mufananidzo 2 unoratidza kutevedzana kwechikamu. Pakudziya kwakadzika, hexagonal, cubic uye pakupedzisira chikamu chelamellar chinoonekwa nekuwedzera surfactant yemukati. Misiyano inoenderana neC8-10 alkyl polyglycoside phase Diagram (Mufananidzo 1) inogona kutsanangurwa nemusiyano alkyl chain chain cuts uye neNhamba yakasiyana yeglucose units mumorekuru (ona pazasi).
