Uma uphuzo oludakayo oluqukethe ama-athomu e-carbon angu-16 noma ngaphezulu nge-molecule ngayinye kusetshenziswa 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 engancibiliki emanzini. i-polyglycosides.Phakathi kwalawa ma-alkyl polyglycosides, izici ezingezona ezomhlaba zikhonya ngenxa yeketango elide le-alkyl.Lawa awasetshenziswa njengama-surfactants kodwa asetshenziswa ngokuyinhloko njengama-emulsifiers ekwenziweni kwezimonyo.
Ukusabela okuphawuliwe kweglucose ngama-dodecanols/tetradecanols kusebenza kakhulu ekuhlanganisweni kwe-alkyl polyglycosides engancibiliki emanzini, njenge-cetyl/octadecyl polyglycosides.Ukusabela okubangelwa i-Acid kwenzeka emazingeni okushisa afanayo, izingcindezi, kanye nezilinganiso ze-molar phakathi kwe-feedstocks.Kodwa-ke, ngenxa yokuncibilika kwayo okuphansi, le mikhiqizo ilukhuni kakhulu ukuyicwenga kanye nokwenza i-bleach njengama-pastes asekelwe emanzini.Kubalulekile ukukhiqiza imikhiqizo enokuqukethwe okuphansi nombala okhanyayo ngqo ngemva kwesinyathelo sokusabela, ngaleyo ndlela ugweme ukwelashwa okwengeziwe.
Umkhiqizo ongafunwa obaluleke kakhulu i-polyglucose.Inombala ophuzi ngokunsundu futhi ngaleyo ndlela iwohloka kakhulu umbala.Ukwengeza, ukuba khona kokugxila okuphezulu kwe-polyglucose kwenza kube nzima ukugxilisa ingxube yokusabela ngokukhipha i-distillation, ngoba i-polyglucose ijwayele ukubola ngokushesha kakhulu njengoba izinga lokushisa likhuphuka.Lokhu ekugcineni kuphinde kuthikameze izici zokusebenza.
Njengoba izinga lokwakheka kwe-polydextrose likhuphuka kakhulu ngasekupheleni kokusabela, ukusabela kunqamula ngaphambi kwesikhathi cishe ngo-80% wokuguqulwa kwe-glucose ngokwehlisa izinga lokushisa kanye nokunciphisa i-catalyst.Ukuze kuqinisekiswe ikhwalithi yomkhiqizo ofanayo nophindaphindekayo, ukuhlaziywa kwe-inthanethi kusetshenziselwa ukulandelela ngokunembile ukuguqulwa.Ekunqanyulweni, i-glucose engaphenduliwe ikhona njengesiqinile esimisiwe futhi ingasuswa kalula ngokuhlunga okulandelayo.Ngemuva kokususwa kwe-glucose, umkhiqizo uqukethe cishe i-1-2q ye-polydextrose, efakwe emulsified ngamaconsi amahle kakhulu.Ngokukhetha usizo lokuhlunga olufanele, i-polydextrose ingasuswa ngokuphelele esinyathelweni sesibili sokuhlunga.
Umkhiqizo ongenayo i-glycose ne-polydextrose equkethe i-15 kuya ku-30% ye-alkyl polyglycosides ye-alkyl (C 16/18) kanye no-85 kuya ku-70% wotshwala obunamafutha (C16/18-OH) utholakala ngale nqubo.Njengoba umkhiqizo unendawo ephakeme yokuncibilika, imvamisa ukuthengiswa njengento eqinile ngendlela yama-flakes noma ama-pellets.
Amazinga aphezulu otshwala obunamaketanga amade ayamukeleka ngoba izinto zokugcoba eziningi ziqukethe inani elikhulu lotshwala obufanayo.Ngakho-ke, i-alkyl polyglycosides ingasetshenziswa ngokuqondile njenge-alkyl polyglycosides/fatty alcohols.
Izinhlobo zakamuva ze-alkyl polyglycosides ezingancibiliki emanzini ziqukethe cishe u-500% we-alkyl polyglycosides kanye nama-alcohols anamafutha angu-500%. Kulokhu, ingxenye yotshwala obunamafutha isuswa i-vacuum distillation futhi ukubola okushisayo kucindezela ngokugcina izinga lokushisa nesikhathi sokuhlala. ngaphansi ngangokunokwenzeka.(Umfanekiso 7) Lolu hlobo lomkhiqizo olugxilile lunweba kakhulu ububanzi bokusetshenziswa kwe-alkyl polyglycosides engancibiliki emanzini.
