Interfacial properties alkyl polyglycoside derivatives.

Kuratidzira maitiro emukati ealkyl polyglycoside derivatives, tension yepasi / concentration curves yakanyorwa uye iyo yakakosha micelle concentrations(cmc) uye iyo plateau surface tension values ​​pamusoro pecmc yakatemwa kubva kwavari. Iko kukakavara kwemeso kunopesana nemhando mbiri yezvinhu: octyl dodecanol uye decane-yakaongororwa semamwe maparamita. Ma cmc anowanikwa kubva kune aya ma curves anoratidzwa muMufananidzo 8. data inoenderana neC₁₂ alkyl monoglycoside uye a_{C 12/14}alkyl polyglycoside inosanganisirwa kuenzanisa. Zvinogona kuonekwa kuti alkyl polyglycoside glycerol ethers nema carbonates ane high cmc values ​​pane alkyl polyglycosides echeni inofananidzwa kureba ukuwo macmc values ​​emonobutyl ethers akati dererei pane ayo ealkyl polyglycosides.

Iyo yepakati tension kuyerwa kwakaitwa neKri.iss spinning inodonha tensiometer. Kutevedzera maitiro anoshanda, zviyero zvakaitwa mumvura yakaoma (270 ppm Ca: Mg = 5: ll pa surfactant concentration ye 0.15 g / l uye paSO Mufananidzo 9 inoratidza kuenzanisa kwehutano hweC.₁₂alkyl polyglycoside derivatives kurwisa octyl dodecanol. Iye C₁₂mono[1]butyl ether ine yakanyanya kupindirana tension uye nekudaro ndiyo yakadzikira yekubata kumeso nepo C.₁₂monoglycerol ether iri padanho reC₁₂polybutyl ether. Iye C₁₂alkyl polyglycoside inosanganisirwa pakuenzanisa nhema padanho rekupedzisira maviri alkyl polyglycoside derivatives akataurwa. Pakazere, iyo interfacial tension values ​​inopesana neoctyl dodecanol yakakwira. Izvi zvinoreva kuti, pamashandisirwo anoshanda, zvakakosha kuve nechokwadi chekuti surfactant misanganiswa inoshandiswa ine synergism kumafuta epolar.

Mhedzisiro yemubvunzo wefuro seMufananidzo 10. Mafungiro ekupupa kweakasiyana alkyl polyglycoside monoglycerol ethers uye monocarbonates akayerwa nekuenzanisa neC.₁₂alkyl polyglycoside yemhando mbiri dzekuoma kwemvura mukushaikwa kwevhu rakakora. Zviyero zvakaitwa zvinoenderana neDIN 53 902. Iyo C₁₀uye C₁₂alkyl polyglycoside monoglycerol ethers yakagadzira furo guru kupfuura C₁₂alkyl polyglycoside. Foam kugadzikana kwakakura zvakanyanya mune yeC₁₂monoglycerol ether kupfuura munyaya yeC₁₀ kubva pa16°dH. Iye C₁₄alkyl polyglycoside monoglycerol ether haienzaniswi neC₁₀uye C₁₂ zvinobva musimba rayo rinopupuma uye, zvakazara, mitengo yakashata kupfuura C₁₂alkyl polyglycoside. Mamono-carbonates ane alkyl cheni kureba n ye8 ne12 anosiyaniswa neakanyanya kuderera furo mavhoriyamu, sezvingatarisirwa kubva kune hydrophobic alkyl polyglycoside derivative.
