Kaphatikizidwe ka alkyl polyglycoside glycerol ethers

Kaphatikizidwe ka alkyl polyglycoside glycerol ethers kunachitika ndi njira zitatu zosiyana (Chithunzi 2, mmalo mwa osakaniza alkyl polyglycoside, alkyl monoglycoside okha akuwonetsedwa ngati educt).The etherification ya alkyl polyglycoside ndi glycerol ndi njira A imapitirira pansi pa zomwe zimachitika.Kutsegula kwa mphete ya epoksidi ndi njira B kumachitikanso pamaso pa zoyambitsa zoyambira.Njira ina ndi momwe glycerol carbonate imachitira ndi njira C yomwe imatsagana ndi kuchotsedwa kwa CO₂ ndi zomwe Mwachiwonekere zimapitilira kudzera pa epoxide ngati gawo lapakati.

Zomwe zimasakanikirana zimatenthedwa ndi 200 ℃ kwa nthawi ya maola 7 pomwe madzi opangidwawo amasungunuka mosalekeza kuti asamutse chigwirizanocho momwe angathere ku mbali ya mankhwala.Monga momwe zimayembekezeredwa, ma alkyl polyglycoside di- ndi triglycerol ethers amapangidwa kuwonjezera pa ether monoglycerol.Chinthu chinanso chachiwiri ndicho kudzipangira glycerol kupanga oligoglycerol omwe amatha kuchita ndi alkyl polyglycoside mofanana ndi glycerol.Zomwe zili pamwambazi za oligomers zitha kukhala zofunika kwambiri chifukwa zimapititsa patsogolo hydrophilicity motero mwachitsanzo kusungunuka kwamadzi kwazinthuzo.Pambuyo pa etherification, mankhwalawo amatha kusungunuka m'madzi ndikutsuka m'njira yodziwika bwino, mwachitsanzo ndi hydrogen peroxide.

Pansi pazimenezi, kuchuluka kwa etherification kwazinthu sikudalira kutalika kwa unyolo wa alkili polyglycoside yomwe imagwiritsidwa ntchito.Chithunzi 3 chikuwonetsa kuchuluka kwa ma etha a mono-,di- ndi triglycerol mumsanganizo wazinthu zosakayikitsa zautali wosiyanasiyana wa alkili.Zotsatira za C₁₂ alkyl polyglycoside imapereka zotsatira zofananira.Malinga ndi chromatogram ya gasi, mono-,di- ndi triglycerol ethers amapangidwa mu chiŵerengero cha pafupifupi 3:2:1.Zomwe zili mu glycerol ethers ndi pafupifupi 35%.
