Iipropati ezihlangeneyo ze-alkyl polyglycoside derivatives.

Ukubonakalisa iimpawu ze-alkyl polyglycoside derivatives, ukunyanzeliswa komphezulu / ukuxinana kweegophe zarekhodwa kwaye i-micelle concentrations (cmc) kunye ne-plateau surface tension values ​​ngaphezulu kwe-cmc zamiselwa kuzo. Uxinzelelo oluphakathi kobuso ngokuchasene nemodeli yezinto ezimbini: i-octyl dodecanol kunye ne-decane-ziphandwe njengezinye iiparamitha. Amanani e-cmc afunyenwe kula magophe aboniswe kuMfanekiso 8. idatha ehambelanayo ye-C₁₂ alkyl monoglycoside kunye a_{C 12/14}i-alkyl polyglycoside ifakiwe ukuthelekisa. Inokubonwa ukuba ii-alkyl polyglycoside glycerol ethers kunye ne-carbonates zinexabiso eliphezulu le-cmc kune-alkyl polyglycosides zobude bekhonkco elithelekisekayo ngelixa ixabiso le-cmc ye-monobutyl ethers lingaphantsi kancinci kune-alkyl polyglycosides.

Imilinganiselo yoxinzelelo lwangaphakathi lwenziwe nge-Kri.iss spinning drop tensiometer. Ukulinganisa iimeko eziphathekayo, imilinganiselo yenziwa kumanzi anzima (270 ppm Ca: Mg = 5: ll kwi-surfactant concentration ye-0.15 g / l kunye ne-SO Figure 9 ibonisa ukuthelekiswa koxinzelelo lwe-interfacial C.₁₂I-alkyl polyglycoside derivatives ngokuchasene ne-octyl dodecanol. UC₁₂imono[1]butyl ether inelona xinzelelo luphezulu lobuso kwaye kungoko owona msebenzi usezantsi wokuhlangana ngelixa iC₁₂Imonoglycerol ether ikwinqanaba eliphezulu leC₁₂polybutyl ether. UC₁₂I-alkyl polyglycoside ibandakanywe ukuthelekisa ilele kwinqanaba lezinto ezimbini zokugqibela ze-alkyl polyglycoside derivatives ezikhankanywe. Lilonke, amaxabiso oxinzelelo oluphakathi kobuso ngokuchasene ne-octyl dodecanol aphezulu kakhulu. Oku kuthetha ukuba, kwizicelo ezibonakalayo, kubalulekile ukuqinisekisa ukuba imixube ye-surfactant esetyenzisiweyo ine-synergism ngokubhekiselele kwi-oyile ye-polar.

Iziphumo zovavanyo logwebu njengoMzobo 10.Ukuziphatha okugwetyiweyo kweendlela ezahlukeneyo zealkyl polyglycoside monoglycerol ethers kunye nemonocarbonates zalinganiswa ngokuthelekisa neC.₁₂ialkyl polyglycoside yamaxabiso amabini obulukhuni bamanzi ngokungabikho komhlaba otyebileyo. Imilinganiselo yenziwe ngokuhambelana neDIN 53 902. I-C₁₀kunye noC₁₂I-alkyl polyglycoside monoglycerol ethers ivelise umthamo omkhulu wogwebu kune-C₁₂i-alkyl polyglycoside. Uzinzo lwegwebu lukhulu kakhulu kwimeko yeC₁₂i-monoglycerol ether kunemeko yeC₁₀ iphuma kwi-16°dH. UC₁₄ialkyl polyglycoside monoglycerol ether ayithelekisswa neC₁₀kunye noC₁₂ izinto eziphuma kumandla alo agwebu amagwebu kwaye, lilonke, amaxabiso amabi kuneC₁₂i-alkyl polyglycoside. I-mono-carbonates ezinobude be-alkyl chain n ye-8 kunye ne-12 zahlulwa ngemithamo ye-foam ephantsi kakhulu, njengoko kuya kulindeleka kwi-hydrophobic alkyl polyglycoside derivative.
