Rubutun alkyl polyglycoside butyl ethers

Abubuwan da ake buƙata akai-akai na alkyl polyglycosides suna haɓaka kumfa. Koyaya, a cikin aikace-aikace da yawa, ana ɗaukar wannan fasalin a zahiri mara amfani. Sabili da haka, akwai kuma sha'awar haɓaka abubuwan haɓakar alkyl polyglycoside waɗanda ke haɗa aikin tsaftacewa mai kyau tare da ɗan ƙaramin kumfa. Yin la'akari da wannan burin, an haɗa alkyl polyglycoside butyl ether. An sani a cikin wallafe-wallafen cewa za a iya rufe alkyl glycosides tare da alkyl halides ko dimethyl sulfate a cikin maganin ruwa na alkaline.

A kan ma'auni na masana'antu, amsawa a cikin maganin ruwa yana da hasara saboda ba za a iya samun samfurori marasa ruwa ba tare da ƙarin matakan aiki ba. Saboda haka, an samar da tsarin da ba shi da ruwa, wanda aka zayyana a hoto na 6. An fara shigar da alkyl polyglycoside a cikin reactor tare da wuce haddi na butyl chloride kuma mai tsanani zuwa 80 ℃. Ana farawa da amsa ta hanyar ƙara potassium hydroxide a matsayin mai kara kuzari. Bayan an gama abin, an ba da cakudawar dauki, ana tace hazo na potassium chloride kuma an kashe wuce haddi na butyl chloride. Samfurin ya ƙunshi nau'ikan alkyl polyglycosides da alkyl polyglycoside butyl ethers. Bisa ga binciken GC, rabon alkyl monoglycoside, alkyl mono-glycoside monobutyl ether da alkyl monoglycoside polybutyl ether shine 1: 3: 1.5.

Hanyar amsawa don etherification na C₁₂An nuna alkyl polyglycoside a cikin Hoto 7. Abubuwan da ke cikin monoglycoside yana raguwa daga kusan 70% zuwa ƙasa da 20%. A lokaci guda, darajar ga monoether ya tashi zuwa 50%. Mafi yawan ether na monobutyl, mafi yawan ethers za a iya samu daga gare ta. Sai bayan sa'o'i 24 ne aka sami wani gagarumin samuwar polybutyl ethers. Kamar yadda aka zata, abun ciki na polyethers yana ƙaruwa tare da ƙara lokacin amsawa. Koyaya, ƙimar 20% ba ta wuce ba. Matsakaicin matakin etherification shine 1 ~ 3 butyl a kowace naúrar alkyl glycoside. Tasirin amsawar C₁₂Alkyl glycoside ya kasance mafi kyau. A cikin yanayin N = 8 ko 16 alkyl polyglycoside butyl ether, sakamakon ya lalace.

Daga waɗannan misalan guda uku a bayyane yake cewa abubuwan da aka samo daga alkyl glycosides suna samuwa a shirye. Amfanin amfani na musamman da aka yi hasashe ya dogara ne akan kayan aikin saman na waɗannan abubuwan.
