Alkyl Polyglycosides derivatives

Niaj hnub no, alkyl polyglycosides muaj nyob rau hauv qhov ntau txaus thiab ntawm cov nqi sib tw kom lawv siv los ua cov khoom siv raw rau kev tsim cov khoom tshwj xeeb surfactants raws li alkyl polyglycosides yog arousing ntau txaus siab. Yog li, cov khoom surfactants ntawm alkyl polyglycosides, piv txwv li ua npuas ncauj thiab ntub dej, tuaj yeem hloov kho raws li kev hloov pauv tshuaj lom neeg.

Derivation ntawm alkyl glycosides yog ib qho kev ua haujlwm dav dav tam sim no.Muaj ntau hom alkyl glycoside derivatives los ntawm kev hloov nucleophilic.Ntxiv rau cov tshuaj esters lossis ethoxides, ionic alkyl polyglycoside derivatives, xws li sulfates thiab phosphates, kuj tuaj yeem sib xyaw ua ke. .

Pib los ntawm alkyl polyglycosides muaj alkyl chains (R) ntawm 8,10,12,14 thiab 16 carbon atoms (C₈rau C₁₆) thiab qhov nruab nrab ntawm polymerization (DP) ntawm 1.1 txog 1.5, peb series ntawm alkyl polyglycoside derivatives tau npaj. Txhawm rau tshawb xyuas qhov kev hloov pauv ntawm cov khoom siv surfactant hydrophilic lossis hydrophobic substituents tau qhia ua rau alkyl polyglycoside glycerol ethers. (Daim duab 1)

Nyob rau hauv kev pom ntawm lawv cov pab pawg hydroxyl ntau, alkyl polyglycosides yog dhau-functionalized molecules.by deb ntawm cov feem ntau alkyl polyglycoside derivatizations yog nqa tawm los ntawm kev hloov tshuaj ntawm cov dawb thawj hydroxyl pawg ntawm C.⁶ atom. Txawm hais tias thawj pawg hydroxyl muaj ntau dua reactive dua li pawg hydroxyl theem nrab, qhov sib txawv no tsis txaus nyob rau hauv feem ntau kom ua tiav cov tshuaj tiv thaiv uas tsis muaj pab pawg tiv thaiv.Raws li, derivatization ntawm alkyl polyglycoside tuaj yeem xav tau los tsim cov khoom sib xyaw uas muaj cov yam ntxwv cuam tshuam. kev siv zog ntau heev. Kev sib xyaw ua ke ntawm cov pa roj chromatography thiab huab hwm coj spectrometry tau pom tias yog txoj kev tsom xam nyiam. Hauv kev sib txuas ntawm alkyl polyglycoside derivatives, nws tau ua pov thawj zoo siv alkyl polyglycoside nrog tus nqi qis DP ntawm 1.1, hauv qab no hu ua alkyl monoglycosides. Qhov no ua rau cov khoom sib tov tsis tshua muaj thiab ua rau muaj kev cuam tshuam tsawg dua.
