Ukuba ii-alcohols ezinamafutha aqulethe i-16 okanye ngaphezulu iiathom zekhabhoni nge-athom nganye zisetyenziswa ekudibaneni kwe-alkyl polyglycosides, imveliso ephumayo iyanyibilika emanzini kuphela kwindawo ephantsi kakhulu, ngokuqhelekileyo iDP ye-1.2 ukuya ku-2. Zibizwa apha njengealkyl enganyibilikiyo emanzini. i-polyglycosides.Phakathi kwezi alkyl polyglycosides, iimpawu ze-nonpolar zizongamela ngenxa yekhonkco elide le-alkyl.Ezi azisetyenziswa njenge-surfactants kodwa zisetyenziswa ngokuyintloko njenge-emulsifiers kwi-cosmetic formulations.
Ukusabela okubonwayo kwe-glucose kunye ne-dodecanols / tetradecanols ubukhulu becala busebenza kwi-synthesis ye-alkyl polyglycosides engaxutywanga ngamanzi, njenge-cetyl / octadecyl polyglycosides. Nangona kunjalo, ngenxa ye-solubility ephantsi, ezi mveliso zinzima kakhulu ukuzicokisa kunye ne-bleach njengepastes esekwe emanzini. Kubalulekile ukuvelisa iimveliso ezinomxholo ophantsi kunye nombala okhanyayo ngokuthe ngqo emva kwesinyathelo sokuphendula, ngaloo ndlela ugweme unyango olongezelelweyo.
Eyona mveliso ibalulekileyo engafunwayo yi-polyglucose.Ityheli-brown kwaye ngaloo ndlela iwonakala kakhulu umbala. Ukongeza, ubukho boxinzelelo oluphezulu lwe-polyglucose kwenza kube nzima ukugxila kumxube wokuphendula nge-distillation, kuba i-polyglucose ithande ukubola ngokukhawuleza njengoko amaqondo obushushu enyuka. Oku ekugqibeleni kuchaphazela iimpawu zokusebenza.
Ekubeni izinga lokubunjwa kwe-polydextrose landa kakhulu ekupheleni kokuphendula, ukusabela kuphelisa ngokukhawuleza malunga ne-80% yokuguqulwa kwe-glucose ngokunciphisa ubushushu kunye nokunciphisa i-catalyst. Ukuqinisekisa umgangatho wemveliso efanayo kunye nokuveliswa kwakhona, uhlalutyo lwe-intanethi lusetyenziselwa ukulandelela ngokuchanekileyo ukuguqulwa. Ekupheleni, i-glucose engaphendulwanga ikhona njengesigxina esimisiweyo kwaye inokususwa ngokulula ngokuhluzwa okulandelayo. Emva kokususwa kwe-glucose, imveliso iqulethe malunga ne-1-2q ye-polydextrose, e-emulsified ngamaconsi amahle kakhulu. Ngokukhetha uncedo olufanelekileyo lokucoca, i-polydextrose inokususwa ngokupheleleyo kwinqanaba lesibini lokuhluza.
Imveliso enkulu ye-glycose kunye ne-polydextrose-free equkethe i-15 ukuya kwi-30% ye-chain-chain (C 16/18) i-alkyl polyglycosides kunye ne-85 ukuya kwi-70% yotywala obunamafutha (C16 / 18-OH) ifunyenwe ngale nkqubo. Ekubeni imveliso inendawo ephakamileyo yokunyibilika, ngokuqhelekileyo ithengiswa njengento eqinile ngendlela yeeflakes okanye iipellets.
Amanqanaba aphezulu otywala be-long-chain amkelekile kuba izinto zokuthambisa ezininzi zinezixa ezikhulu zotywala obufanayo. Ke ngoko, ialkyl polyglycosides ingasetyenziswa ngokuthe ngqo njengealkyl polyglycosides/fatty alcohols.
Iintlobo zamva nje ze-alkyl polyglycosides ezinganyibilikiyo ngamanzi ziqulathe malunga ne-500% ye-alkyl polyglycosides kunye ne-500% ye-alcohol enamafutha. Kule meko, inxalenye ye-alcohol enamafutha isuswa yi-vacuum distillation kunye nokubola kwe-thermal kucinezelwe ngokugcina ubushushu kunye nexesha lokuhlala. iphantsi kangangoko. (Umfanekiso 7) Olu hlobo lwemveliso olugxininisiweyo lwandisa kakhulu uluhlu lwezicelo ze-alkyl polyglycosides ezingenamanzi.
