Iimveliso zeAlkyl Polyglycosides

Kule mihla, i-alkyl polyglycosides ifumaneka ngobungakanani obaneleyo kwaye ngeendleko zokukhuphisana ukuze ukusetyenziswa kwazo njengemathiriyeli ekrwada kuphuhliswe ii-surfactants ezintsha ezisekelwe kwi-alkyl polyglycosides kuvusa umdla omkhulu. Ke, iipropathi ze-surfactants ze-alkyl polyglycosides, umzekelo igwebu kunye nokumanzisa, zinokutshintshwa njengoko zifunwa yinguqu yeekhemikhali.

Ukukhutshwa kwe-alkyl glycosides ngumsebenzi obandakanyekayo ngokubanzi okwangoku.Zininzi iintlobo ze-alkyl glycoside derivatives ngendlela ye-nucleophilic substitution.Ngaphezu kokusabela nge-esters okanye i-ethoxides, i-ionic alkyl polyglycoside derivatives, njenge-sulfates kunye ne-phosphates, inokuthi yenziwe .

Ukuqala kwi-alkyl polyglycosides ene-alkyl chain(R) ye-8,10,12,14 kunye ne-16 yeathom zekhabhoni.₈ukuya kuC₁₆）kunye neqondo eliphakathi lepolymerization (DP) ye-1.1 ukuya kwi-1.5, uthotho oluthathu lwe-alkyl polyglycoside derivatives lwalungiswa. Ukuze kuphandwe utshintsho kwiipropati ze-surfactant i-hydrophilic okanye i-hydrophobic substituents yaziswa ekhokelela kwi-alkyl polyglycoside glycerol ethers. (Umfanekiso 1)

Ngokujonga uninzi lwamaqela abo e-hydroxyl, i-alkyl polyglycosides ziimolekyuli ezisebenza ngokugqithisileyo. Ukuza kuthi ga ngoku ezona zinto ziphuma kwi-alkyl polyglycoside zenziwa lutshintsho lwekhemikhali yeqela lasimahla le-hydroxyl kwi-C.⁶ athom. Nangona amaqela aphambili e-hydroxyl esebenza ngakumbi kunamaqela e-hydroxyl yesibini, lo mahluko awanelanga kwiimeko ezininzi ukufezekisa impendulo ekhethiweyo ngaphandle kwamaqela okukhusela. umzamo omkhulu wohlalutyo. Ukudibanisa i-chromatography yegesi kunye ne-mass spectrometry ibonakaliswe njengendlela yokuhlalutya ekhethiweyo. Kwi-synthesis ye-alkyl polyglycoside derivatives, ibonakalise isebenzayo ukusebenzisa i-alkyl polyglycoside enexabiso eliphantsi le-DP ye-1.1, kwezi zilandelayo zibizwa ngokuba yi-alkyl monoglycosides. Oku kukhokelela kwimixube yemveliso engantsonkothanga kwaye njengesiphumo sohlahlelo olungantsonkothanga.
