Iimveliso zeAlkyl Polyglycosides

Kule mihla, ii-alkyl polyglycosides zifumaneka ngobungakanani obaneleyo kwaye ngeendleko zokukhuphisana ukuze ukusetyenziswa kwazo njengemathiriyeli ekrwada kuphuhliswe ii-surfactants ezitsha 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. Kukho iintlobo ezininzi 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 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 ukusabela okukhethiweyo 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.
