Kaphatikizidwe ka alkyl polyglycoside butyl ethers

Katundu wofunikira pafupipafupi wa alkyl polyglycosides ndiwowonjezera kutulutsa.Komabe, m'mapulogalamu ambiri, izi zimawonedwa ngati zosathandiza.Chifukwa chake, palinso chidwi chopanga zotumphukira za alkyl polyglycoside zomwe zimaphatikiza kuyeretsa kwabwino komanso kachitidwe kakang'ono ka thovu.Poganizira cholinga ichi, alkyl polyglycoside butyl ether adapangidwa.Zimadziwika m'mabuku kuti alkyl glycosides amatha kukhala ndi alkyl halides kapena dimethyl sulfate muzosakaniza zamchere zamchere.

Pazinthu zamafakitale, zomwe zimachitika mumadzi amadzimadzi zimakhala zovuta chifukwa zinthu zopanda madzi sizingapeŵedwe popanda njira zina zogwirira ntchito.Chifukwa chake, njira yopanda madzi idapangidwa, yomwe yafotokozedwa mu Chithunzi 6. Alkyl polyglycoside imalowetsedwa mu riyakitala ndi kuchuluka kwa butyl chloride ndikutenthedwa mpaka 80 ℃.Zomwe zimachitika zimayambitsidwa ndi kuwonjezera potassium hydroxide monga chothandizira.Mukamaliza kuchitapo kanthu, zomwe zimasakanikirana zimachepetsedwa, potassium chloride precipitate imasefedwa ndipo owonjezera butyl chloride amachotsedwa.Mankhwalawa amapangidwa ndi ma alkyl polyglycosides osiyanasiyana ndi ma alkyl polyglycoside butyl ethers.Malinga ndi kusanthula kwa GC, chiŵerengero cha alkyl monoglycoside, alkyl mono-glycoside monobutyl ether ndi alkyl monoglycoside polybutyl ether ndi 1:3:1.5.

Zotsatira za etherification ya C₁₂alkyl polyglycoside akuwonetsedwa mu Chithunzi 7. Zomwe zili mu monoglycoside zimatsika kuchokera kuzungulira 70% kufika kuchepera 20%.Nthawi yomweyo, mtengo wa monoether umakwera mpaka 50%.Monobutyl ether yochulukirapo imapezeka, ma ether a polybutyl amatha kupangidwa kuchokera pamenepo.Pokhapokha pambuyo pa 24hours pali kupanga kwakukulu kwa polybutyl ethers.Monga zikuyembekezeredwa, zomwe zili mu polyethers zimawonjezeka ndi nthawi yowonjezereka.Komabe, mtengo wa 20% sunapitirire.Digiri yapakati ya etherification ndi 1 ~ 3 butyl pa alkyl glycoside unit.Zotsatira za C₁₂alkyl glycoside anali abwino kwambiri.Pankhani ya N =8 kapena 16 alkyl polyglycoside butyl ether, zotsatira zake zidawonongeka.

Kuchokera pazitsanzo zitatuzi zikuwonekeratu kuti zotumphukira za alkyl glycosides zimapezeka mosavuta.Zogwiritsidwa ntchito mwapadera zomwe zikuganiziridwa zimadaliranso ntchito zapamtunda za zotumphukira izi.
