Imikhiqizo ye-Alkyl Polyglycosides

Kulezi zinsuku, ama-alkyl polyglycosides atholakala ngenani elanele nangezindleko ezincintisanayo ukuze ukusetshenziswa kwawo njengempahla eluhlaza ukuze kuthuthukiswe ama-surfactants amasha asekelwe ku-alkyl polyglycosides kuvusa isithakazelo esikhulu. Ngakho-ke, izakhiwo zama-surfactants ze-alkyl polyglycosides, isibonelo igwebu nokumanzisa, zingashintshwa njengoba kudingwa ukuguqulwa kwamakhemikhali.

Ukukhishwa kwe-alkyl glycosides kuwumsebenzi owenziwa kabanzi njengamanje.Kunezinhlobo eziningi zokuphuma kwe-alkyl glycoside ngokushintshwa kwe-nucleophilic.Ngaphezu kokusabela nge-ester noma i-ethoxides, okuphuma ku-ionic alkyl polyglycoside, njengama-sulfate nama-phosphates, kungabuye kwenziwe. .

Kusukela ku-alkyl polyglycosides enamaketanga e-alkyl(R) angama-8,10,12,14 kanye nama-athomu ekhabhoni ayi-16.₈kuye C₁₆） kanye nesilinganiso sedigri ye-polymerization(DP) ye-1.1 kuya ku-1.5, uchungechunge oluthathu lokuphuma kokuphuma kwe-alkyl polyglycoside lwalungiswa. Ukuze kuphenywe uguquko lwezakhiwo ze-surfactant kwafakwa esikhundleni se-hydrophilic noma se-hydrophobic okuholela kuma-alkyl polyglycoside glycerol ethers. (Umfanekiso 1)

Ngenxa yamaqembu awo amaningi e-hydroxyl, ama-alkyl polyglycosides angama-molecule asebenza ngokweqile.⁶ i-athomu. Nakuba amaqembu e-hydroxyl eyinhloko esebenza kakhulu kunamaqembu e-hydroxyl yesibili, lo mehluko awanele ezimweni eziningi ukufeza ukusabela okukhethiwe ngaphandle kwamaqembu avikelayo. Ngokuvumelana nalokho, ukukhishwa kwe-alkyl polyglycoside kungalindeleka njalo ukuthi kukhiqize ingxube yomkhiqizo okubandakanya ukuhlukaniswa kwezinhlamvu. umzamo omkhulu wokuhlaziya. Inhlanganisela ye-gas chromatography kanye ne-mass spectrometry yaboniswa njengendlela yokuhlaziya ekhethwayo. Ekuhlanganisweni kokuphuma kokuphuma kwe-alkyl polyglycoside, kubonakale kuphumelela ukusebenzisa i-alkyl polyglycoside enenani eliphansi le-DP elingu-1.1, kulokhu okulandelayo okubizwa ngokuthi i-alkyl monoglycosides. Lokhu kuholela ekuhlanganiseni okuncane komkhiqizo okuyinkimbinkimbi futhi njengomphumela wokuhlaziya okunzima kakhulu.
