Ngati zakumwa zoledzeretsa zomwe zimakhala ndi maatomu a kaboni 16 kapena kupitilira apo pa molekyulu zimagwiritsidwa ntchito popanga alkyl polyglycosides, zomwe zimapangidwira zimasungunuka m'madzi pokhapokha pazambiri zotsika kwambiri, nthawi zambiri DP ya 1.2 mpaka 2. Pambuyo pake amatchedwa alkyl osasungunuka m'madzi. polyglycosides.Pakati pa ma alkyl polyglycosides, ma alkyl polyglycosides awa, mawonekedwe a nonpolar ndi omwe amachulukirachulukira chifukwa cha unyolo wautali wa alkyl.Izi sizimagwiritsidwa ntchito ngati surfactants koma zimagwiritsidwa ntchito makamaka ngati emulsifiers popanga zodzikongoletsera.
Zomwe zimachitika shuga ndi dodecanols/tetradecanols zimagwira ntchito kwambiri pakuphatikizika kwa madzi osasungunuka alkyl polyglycosides, monga cetyl/octadecyl polyglycosides.Acid catalyzed reactions imachitika pa kutentha kofanana, kupsinjika, ndi ma molar ratios pakati pa feedstocks.Komabe, chifukwa cha kusungunuka kwawo kochepa, zinthuzi zimakhala zovuta kuziyenga ndikuziyeretsa ngati phala lamadzi.Ndikofunikira kutulutsa zinthu zomwe zili ndi otsika komanso utoto wopepuka mwachindunji pambuyo pa sitepe yochitira, motero kupewa chithandizo china.
Chofunikira kwambiri chomwe sichingafuneke ndi polyglucose. Ndi yachikasu-bulauni ndipo motero imawonongeka kwambiri.Kuphatikiza apo, kupezeka kwa kuchuluka kwa shuga wa polyglucose kumapangitsa kuti zikhale zovuta kuyang'ana momwe zimachitikira ndi distillation, chifukwa polyglucose imakonda kuwola mwachangu kwambiri kutentha kumakwera.Izi zimasokonezanso magwiridwe antchito.
Popeza kuchuluka kwa mapangidwe a polydextrose kumawonjezeka kwambiri kumapeto kwa zomwe zimachitika, zomwe zimachitika zimatha msanga pafupifupi 80% kutembenuka kwa shuga ndikuchepetsa kutentha ndikuchepetsa chothandizira.Kuwonetsetsa kuti chinthucho chili ndi mtundu wofananira komanso wopangidwanso, kusanthula kwapaintaneti kumagwiritsidwa ntchito kutsata kusinthika.Pakutha, glucose osagwiritsidwa ntchito amakhalapo ngati cholimba choyimitsidwa ndipo amatha kuchotsedwa mosavuta ndikusefera kotsatira.Pambuyo pa kuchotsedwa kwa shuga, mankhwalawa amakhala ndi pafupifupi 1-2q ya polydextrose, yomwe imapangidwa ndi madontho abwino kwambiri.Posankha chithandizo choyenera cha fyuluta, polydextrose ikhoza kuchotsedwa kwathunthu mu gawo lachiwiri la kusefera.
Chogulitsa kwambiri cha glycose ndi polydextrose chokhala ndi 15 mpaka 30% ya unyolo wautali (C 16/18) alkyl polyglycosides ndi 85 mpaka 70% ya mowa wamafuta (C16/18-OH) amapezedwa ndi njirayi.Popeza mankhwalawa ali ndi malo osungunuka okwera, nthawi zambiri amagulitsidwa ngati olimba ngati ma flakes kapena pellets.
Kuchuluka kwa zakumwa zoledzeretsa zazitali ndizovomerezeka chifukwa mafuta odzola ambiri amakhala ndi mowa wambiri womwewo.Chifukwa chake, alkyl polyglycosides atha kugwiritsidwa ntchito mwachindunji ngati alkyl polyglycosides/mafuta oledzeretsa.
Mitundu yaposachedwa kwambiri ya alkyl polyglycosides osasungunuka m'madzi imakhala ndi pafupifupi 500% alkyl polyglycosides ndi 500% yamafuta oledzeretsa. Apa, gawo lina la mowa wonyezimira limachotsedwa ndi vacuum distillation ndipo kuwonongeka kwamafuta kumachepetsedwa posunga kutentha ndi nthawi yokhalamo. otsika momwe ndingathere.(Chithunzi 7) Mtundu wa mankhwalawa umakulitsa kwambiri kuchuluka kwa ntchito za alkyl polyglycosides osasungunuka m'madzi.
