Ethyl cellulose solubility ka ethanol
Ethyl cellulose ke polymer ea maiketsetso e sebelisoang hangata liindastering tse fapaneng, ho kenyeletsoa meriana, lijo le tlhokomelo ea motho. E 'ngoe ea lintho tse ka sehloohong tsa ethyl cellulose ke ho qhibiliha ha eona ho li-solvents tse fapaneng, tse bohlokoa bakeng sa ts'ebeliso ea eona e fapaneng. Ethanol ke e 'ngoe ea lihlapolli tse ka sebelisoang ho qhibilihisa ethyl cellulose.
Ho qhibiliha ha ethyl cellulose ka ethanol ho itšetlehile ka lintlha tse fapaneng tse kang tekanyo ea ethylation, boima ba molek'hule ea polymer, le mocheso oa motsoako. Ka kakaretso, ethyl cellulose e nang le tekanyo e phahameng ea ethylation e qhibiliha haholoanyane ka ethanol ha e bapisoa le ba nang le tekanyo e tlaase ea ethylation. Boima ba molek'hule ea polymer le bona bo phetha karolo, kaha li-polymers tse phahameng tsa boima ba limolek'hule li ka hloka hore ho be le ethanol e ngata kapa nako e telele ho qhibiliha.
Mocheso oa motsoako o boetse o ama ho qhibiliha ha ethyl cellulose ka ethanol. Lithempereichara tse phahameng li ka eketsa ho qhibiliha ha polymer ka lebaka la matla a matla a kinetic a limolek'hule tse qhibilihisang, tse ka thusang ho senya liketane tsa polymer le ho nolofatsa mokhoa oa ho qhibiliha. Leha ho le joalo, mocheso ha oa lokela ho feta moeli o itseng kaha o ka etsa hore polymer e fokotsehe kapa e lahleheloe ke botšepehi ba eona.
Ka kakaretso, ethyl cellulose e nkoa e le e qhibilihang haholoanyane ka har'a ethanol ha e bapisoa le metsoako e meng e tloaelehileng e kang metsi, methanol le acetone. Ethanol ke motsoako oa polar, 'me polarity ea eona e ka thusa ho senya maqhama a haedrojene pakeng tsa liketane tsa polymer, e leng ho lumellang hore polymer e qhale.
