Rubutun alkyl polyglycoside glycerol ethers

Ana yin kira na alkyl polyglycoside glycerol ethers ta hanyoyi daban-daban guda uku (Figure2, maimakon cakuda alkyl polyglycoside, kawai alkyl monoglycoside an nuna shi azaman educt).Etherification na alkyl polyglycoside tare da glycerol ta hanyar A yana samuwa a ƙarƙashin yanayin amsawa na asali.Buɗe zobe na epoxide ta hanyar B shima yana faruwa a gaban abubuwan haɓakawa na asali.Wani madadin shine amsawa tare da glycerol carbonate ta hanyar C wanda ke tare da kawar da CO₂ kuma wanda Mai yiwuwa yana samuwa ta hanyar epoxide a matsayin matsakaicin mataki.

A dauki cakuda da ake sa'an nan mai tsanani 200 ℃ a kan tsawon 7 hours a lokacin da ruwan kafa da aka ci gaba distilled kashe don kawar da ma'auni kamar yadda ya zuwa yanzu iya zuwa samfurin gefen.Kamar yadda aka zata, alkyl polyglycoside di- da triglycerol ethers an kafa su ban da monoglycerol ether.Wani abin da ya faru na biyu shine ƙaddamar da kai na glycerol don samar da oligoglycerol waɗanda ke da ikon amsawa tare da alkyl polyglycoside daidai da glycerol.Irin wannan babban abun ciki na oligomers mafi girma na iya zama kyawawa gabaɗaya saboda suna ƙara haɓaka hydrophilicity kuma saboda haka misali mai narkewar ruwa na samfuran.Bayan etherification, samfurori za a iya narkar da su a cikin ruwa da kuma bleached a cikin hanyar da aka sani, misali tare da hydrogen peroxide.

A ƙarƙashin waɗannan halayen halayen, matakin etherification na samfuran ya kasance mai zaman kansa daga tsayin sarkar alkyl na alkyl polyglycoside da aka yi amfani da shi.Hoto3 yana nuna adadin abubuwan da ke cikin mono-, di- da triglycerol ethers a cikin cakuda ɗanyen samfurin don tsayin sarkar alkyl huɗu daban-daban.Ra'ayin C₁₂ alkyl polyglycoside yana samar da sakamako na al'ada.Bisa ga chromatogram gas, mono-, di- da triglycerol ethers an kafa su a cikin rabo na kusan 3: 2: 1.Jimlar abun ciki na glycerol ethers yana kusa da 35%.
