Sifooyinka Kiimikaad ee Alkyl Polyglycosides-dabeecadda wajiga
Nidaamyada binary

Waxqabadka aadka u wanaagsan ee surfactants ayaa asal ahaan sabab u ah saameyno jireed iyo kiimiko oo gaar ah. Tani waxay khusaysaa hal dhinac guryaha interface iyo dhinaca kale habdhaqanka xalka, sida habdhaqanka wajiga. Marka la barbar dhigo ethoxylates aalkolada dufanka leh (alkyl polyglycol ethers), cabirrada physicochemical ee alkyl glycosides ilaa hadda wax yar baa la darsay. Daraasadahaan, alkyl polyglycosides ayaa la ogaaday inay leeyihiin sifooyin muhiim ah, kuwaas oo, xaaladaha qaarkood, ay aad uga duwan yihiin kuwa kale ee aan-ionic ahayn. Natiijooyinka ilaa hadda la helay ayaa lagu soo koobay sidan. Kala duwanaanshaha weyn ee la xidhiidha habdhaqanka ethoxylates khamriga dufanka leh ayaa si gaar ah cajiib u ahaa.

Marka la barbardhigo daraasadaha habaysan ee etoxylates-ka dufanka leh, ilaa hadda dhawr daraasadood oo ku lug leh walxo nadiif ah oo kala duwan ayaa lagu sameeyay habdhaqanka wejiga alkyl Polyglycosides. Marka la barbardhigo natiijooyinka la helay, waxaa muhiim ah in maskaxda lagu hayo in Joogitaanka qaybaha labaad ay saameyn weyn ku leeyihiin faahfaahinta jaantusyada wajiga. Si kastaba ha ahaatee, indho-indhaynta aasaasiga ah ayaa laga samayn karaa habdhaqanka wajiga alkyl glycosides. Habdhaqanka wajiga ee farsamada C8-10 Alkyl polyglycoside(C8-10 APG) ayaa lagu muujiyay (Jaantus1). Heerkulka ka sarreeya 20 ℃, C8-10 APG wuxuu u muuqdaa walaac aad u sarreeya oo ku jira wajiga isotropic kaas oo viscosity-ku si aad ah u kordho. Marxaladda lyotropic-ga birefringent ee texture nematic ayaa lagu sameeyay qiyaastii 95% miisaan ahaan, kaas oo isu beddela qiyaastii 98% miisaan ahaan gobolka laba-waji oo daruuro leh oo dareere ah iyo alkyl polyglycoside adag. Heerkul aad u hooseeya, wejiga crystalline dareeraha lamellar ayaa sidoo kale lagu arkay inta u dhaxaysa 75 iyo 85% miisaan ahaan.
Silsilad gaaban oo saafi ah n-octyl-β-D-glucoside, jaantuska wejiga waxaa si faahfaahsan u baaray Nilsson et al. iyo Sakya et al. wejiyada shaqsiga ah ayaa si dhow loogu sifeeyay Hababka sida NMR iyo xagal yar oo raajada xagasha (SAXS). Jaantuska 2 wuxuu muujinayaa isku xigxiga wajiga. Heerkulka hoose, laba geesood, cubic iyo ugu dambeyntii weji lamellar ah ayaa lagu arkay iyadoo ay sii kordhayso nuxurka dusha sare. Farqiga u dhexeeya C8-10 alkyl polyglycoside wejiga jaantuska (Jaantuska 1) waxa lagu sharxi karaa kala duwanaansho gooyn dhererka silsiladda alkyl iyo tiro kala duwan oo unugyada gulukooska ee molecule (eeg hoos).
