Li-derivatives tsa Alkyl Polyglycosides

Matsatsing ana, li-alkyl polyglycosides li fumaneha ka bongata bo lekaneng le ka litšenyehelo tsa tlholisano e le hore tšebeliso ea tsona e le thepa e tala bakeng sa nts'etsopele ea li-surfactants tse ncha tse thehiloeng ho alkyl polyglycosides e tsosa thahasello e kholo. Kahoo, thepa ea li-surfactants ea alkyl polyglycosides, mohlala, foam le ho koloba, e ka fetoloa kamoo ho hlokahalang ka phetoho ea lik'hemik'hale.

Ho na le mefuta e mengata ea lihlahisoa tsa alkyl glycoside ka nucleophilic substitution. Ho phaella tabeng ea ho itšoara ka li-ester kapa ethoxides, li-derivatives tsa ionic alkyl polyglycoside, tse kang sulfate le phosphates, li ka boela tsa etsoa. .

Ho qala ho alkyl polyglycosides e nang le liketane tsa alkyl(R) tsa 8,10,12,14 le 16 liathomo tsa khabone.₈ho C₁₆）le tekanyo e tloaelehileng ea polymerization(DP) ea 1.1 ho isa ho 1.5, lihlopha tse tharo tsa lihlahisoa tsa alkyl polyglycoside li ile tsa lokisoa. E le ho batlisisa phetoho ea thepa ea surfactant ho ile ha hlahisoa li-substituents tsa hydrophilic kapa hydrophobic tse lebisang ho alkyl polyglycoside glycerol ethers. (Setšoantšo sa 1)

Ka lebaka la lihlopha tsa bona tse ngata tsa hydroxyl, alkyl polyglycosides ke limolek'hule tse sebetsang ho feta tekano.⁶ athomo. Le hoja lihlopha tsa mantlha tsa hydroxyl li sebetsa ka thata ho feta lihlopha tsa bobeli tsa hydroxyl, phapang ena ha e lekane maemong a mangata ho finyella karabelo e khethehileng ntle le lihlopha tse sireletsang. boiteko bo boholo ba ho sekaseka. Ho ile ha bontšoa hore motsoako oa khase chromatography le mass spectrometry ke mokhoa o ratoang oa ho hlahloba. Tšimolohong ea lihlahisoa tsa alkyl polyglycoside, ho bonahetse ho sebetsa ho sebelisa alkyl polyglycoside e nang le boleng bo tlase ba DP ea 1.1, ho tse latelang tse bitsoang alkyl monoglycosides. Sena se lebisa mefuteng e sa rarahanang ea lihlahisoa 'me ka lebaka la litlhahlobo tse thata haholo.
