Ukukhiqizwa kwe-alkyl polyglycosides engancibiliki emanzini
Uma uphuzo oludakayo oluqukethe ama-athomu e-carbon angu-16 noma ngaphezulu nge-molecule ngayinye lusetshenziswa ekuhlanganiseni kwe-alkyl polyglycosides, umkhiqizo owumphumela uncibilika emanzini lapho kugxilwe khona okuphansi kakhulu, ngokuvamile okuyi-DP ka-1.2 kuya ku-2. Ngemva kwalokhu kubizwa ngokuthi i-alkyl polyglycosides enganyibiliki emanzini.Amon...Funda kabanzi -
Izidingo zokukhiqizwa kwezimboni zama-alkyl polyglycosides ancibilikayo emanzini
Izidingo zokuklama zesitshalo sokukhiqiza i-alkyl glycoside ezisekelwe ku-Fisher synthesis zincike kakhulu ohlotsheni lwe-carbohydrate esetshenzisiwe kanye nobude beketanga lotshwala obusetshenzisiwe.Ukukhiqizwa kwama-alkyl glycosides ancibilika emanzini asekelwe ku-octanol/decanol kanye ne-dodecanol/tetradecanol kwethulwa okokuqala...Funda kabanzi -
Izinqubo ze-synthesis zokukhiqizwa kwe-alkyl polyglycosides
Ngokuyisisekelo, inqubo yokusabela yawo wonke ama-carbohydrate ahlanganiswe nguFischer nge-alkyl glycosides ingancishiswa ibe izinhlobo ezimbili zezinqubo, okungukuthi, ukuhlanganiswa okuqondile kanye ne-transacetalization. Kuzo zombili izimo, ukusabela kungase kuqhubeke ngamaqoqo noma ngokuqhubekayo. Ngaphansi kokuhlanganiswa okuqondile, i-carbohydrate ...Funda kabanzi -
Ubuchwepheshe Nokukhiqiza kwe-Alkyl Polyglycosides-Degree of polymerization
Ngokusebenzisa i-polyfunctionality yama-carbohydrate, ukusabela kwe-acid catalyzed Fischer kwenziwa ukuze kukhiqizwe ingxube ye-oligomer lapho ngokwesilinganiso iyunithi ye-glycation engaphezu kweyodwa inamathiselwe ku-microsphere yotshwala. Isilinganiso senani lamayunithi e-glycose axhunywe eqenjini lotshwala lichazwa njenge...Funda kabanzi -
Ubuchwepheshe Nokukhiqizwa kwe-Alkyl Polyglycosides-Izinto ezingavuthiwe zokukhiqiza
Kunezindlela eziningana zokulungiselela i-alkyl polyglycosides noma i-alkyl polyglucosides izingxube. Izindlela ezihlukahlukene zokwenziwa zisukela emigwaqweni yokwenziwa ye-stereotactic esebenzisa amaqembu okuzivikela (okwenza inhlanganisela ikhethe kakhulu) kuya emigwaqweni yokwenziwa engakhethi (ukuxuba ama-isomer nama-oligomers).Funda kabanzi -
Umlando we-Alkyl Polyglycosides - Chemistry
