Izici zokusebenzelana kwe-alkyl polyglycoside derivatives.

Ukuze kubonakale izici zokuhlanganisa ubuso zokuphuma kokuphuma kwe-alkyl polyglycoside, ukushuba kwendawo/amajika okugxilisa kwarekhodwa futhi ukugxilisa okubalulekile kwe-micelle(cmc) kanye namanani okudonsa phezulu kwethafa ngaphezulu kwe-cmc kwanqunywa kuwo. Ukungezwani kobuso ngokumelene nezinto ezimbili eziyimodeli: i-octyl dodecanol ne-decane-ziphenywe njengamapharamitha engeziwe. Amanani e-cmc atholwe kula majika aboniswa kuMfanekiso 8. idatha ehambisanayo ye-C₁₂ i-alkyl monoglycoside kanye ne-a_{C 12/14}i-alkyl polyglycoside ifakiwe ukuze iqhathaniswe. Kungabonakala ukuthi ama-alkyl polyglycoside glycerol ethers nama-carbonates anamanani aphezulu we-cmc kune-alkyl polyglycosides yobude beketango obuqhathanisekayo kuyilapho amanani e-cmc e-monobutyl ethers athi ukuma aphansi kunalawo e-alkyl polyglycosides.

Izilinganiso zokungezwani phakathi kobuso zenziwe nge-Kri.iss spinning drop tensiometer. Ukulingisa izimo ezingokoqobo, izilinganiso zenziwe emanzini aqinile (270 ppm Ca :Mg= 5: ll ekuhlanganiseni kwe-surfactant ye-0.15 g/l futhi ku-SO Umfanekiso 9 ubonisa ukuqhathanisa ukungezwani kobuso buka-C.₁₂I-alkyl polyglycoside derivatives ngokumelene ne-octyl dodecanol. I-C₁₂I-mono[1]i-butyl ether inokungezwani okuphezulu kakhulu kobuso futhi yingakho umsebenzi wokuhlangana okuphansi kakhulu kuyilapho i-C₁₂I-monoglycerol ether isezingeni eliphakeme le-C₁₂i-polybutyl ether. I-C₁₂I-alkyl polyglycoside efakiwe uma iqhathaniswa ileleveli yokuphuma kokuphuma kwe-alkyl polyglycoside okugcina okukhulunywe ngakho. Sekukonke, amanani we-interface tension ngokumelene ne-octyl dodecanol aphakeme uma kuqhathaniswa. Lokhu kusho ukuthi, ekusebenzeni okungokoqobo, kubalulekile ukuqinisekisa ukuthi izingxube ze-surfactant ezisetshenziswayo zinokusebenzisana maqondana nowoyela we-polar.

Umphumela wokuhlolwa kwegwebu njengoMfanekiso 10.Ukuziphatha okunegwebu kwezinhlobonhlobo ze-alkyl polyglycoside monoglycerol ethers nama-monocarbonates kukalwa ngokuqhathanisa no-C.₁₂i-alkyl polyglycoside yamanani amabili obulukhuni bamanzi lapho ungekho umhlabathi onamafutha. Izilinganiso zenziwe ngokuhambisana ne-DIN 53 902. I-C₁₀kanye no-C₁₂i-alkyl polyglycoside monoglycerol ethers ikhiqize ivolumu yegwebu elikhulu kune-C₁₂i-alkyl polyglycoside. Ukuzinza kwegwebu kukhulu kakhulu esimweni se-C₁₂i-monoglycerol ether kunesimo se-C₁₀ iphuma ku-16°dH. I-C₁₄i-alkyl polyglycoside monoglycerol ether ayiqhathanisi ne-C₁₀kanye no-C₁₂ okuphuma kuyo emandleni ayo agwebu, futhi, sekukonke, amazinga abi kakhulu kune-C₁₂i-alkyl polyglycoside. Ama-mono-carbonate anobude beketango le-alkyl n ka-8 kanye no-12 ahlukaniswa ngamavolumu egwebu aphansi kakhulu, njengoba kungalindeleka kokuphuma kokunye okuphuma ku-hydrophobic alkyl polyglycoside.
