Qalabaynta alkyl polyglycoside glycerol ethers

Isku-dubaridka alkyl polyglycoside glycerol ethers waxaa lagu fuliyay saddex hab oo kala duwan (Jaantus2, halkii laga heli lahaa isku-darka alkyl polyglycoside, kaliya alkyl monoglycoside ayaa lagu muujiyay sida educt).Etherification alkyl polyglycoside leh glycerol habka A waxay ku socotaa xaaladaha falcelinta aasaasiga ah.Furitaanka giraanta epoxide ee habka B sidoo kale wuxuu ku dhacaa joogitaanka kicinta aasaasiga ah.Beddelku waa falcelinta glycerol carbonate ee habka C kaas oo ay weheliso baabi'inta CO₂ iyo Kaas oo la filayo inuu ku sii socdo epoxide sida marxaladda dhexe.

Isku darka falcelinta ayaa markaa lagu kululeeyaa 200 ℃ muddo 7 saacadood ah taas oo biyaha la sameeyay ay si joogto ah u nadiifinayaan si ay u daadiyaan dheellitirka inta suurtogalka ah ee dhinaca alaabta.Sida la filayo, alkyl polyglycoside di- iyo ethers triglycerol ayaa la sameeyay marka lagu daro eter monoglycerol.Falcelinta kale ee labaad waa is-condensation of glycerol si ay u sameeyaan oligoglycerols kuwaas oo awood u leh inay la falgalaan alkyl polyglycoside si la mid ah glycerol ah.Waxyaabaha noocan oo kale ah ee oligomers sare waxay noqon karaan kuwo gebi ahaanba la jecel yahay sababtoo ah waxay sii wanaajiyaan hydrophilicity iyo halkan tusaale ahaan milanka biyaha ee alaabta.Etherification ka dib, alaabooyinka waxaa lagu milmi karaa biyo waxaana lagu nadiifin karaa qaab la yaqaan, tusaale ahaan hydrogen peroxide.

Xaaladahan falcelinta, heerka etherification ee alaabtu way ka madax bannaan tahay dhererka silsiladda alkyl ee alkyl polyglycoside ee la isticmaalo.Jaantuska3 waxa uu muujinayaa boqolkiiba waxa ku jira mono-,di- iyo triglycerol ethers ee isku dhafka alaabta ceeriin ee afar dhererka silsiladaha alkyl ee kala duwan.Falcelinta C₁₂ alkyl polyglycoside waxay bixisaa natiijo caadi ah.Marka loo eego chromatogram gaas, mono-, di- iyo ethers triglycerol ayaa lagu sameeyay saamiga qiyaastii 3:2:1.Wadarta guud ee ethers-ka glycerol waa qiyaastii 35%.
