1,1,1,3,3,3-Hexafluoroisopropyl Methacrylate (yokhazikika ndi MEHQ)

Hexafluoroisopropyl methacrylate (HFIP-M) ndi madzi opanda mtundu komanso owonekera, ndipo acidity yake imakhudza kwambiri mtundu wake.Njira yodziwira acidity ya hexafluoroisopropyl methacrylate yafufuzidwa kudzera muzoyesera, ndipo njira zitatu zimagwiritsidwa ntchito Njira zomwe zimagwiritsidwa ntchito kawirikawiri kuti mudziwe acidity: 1) Gwiritsani ntchito njira ya potentiometric kuti muwonetse mapeto a titration, ndikugwiritsa ntchito potentiometer yodziwikiratu mu titration;2) Gwiritsani ntchito chizindikiro kuti muwone kumapeto kwa titration;3) Choyamba wachotsa asidi mu chitsanzo ndi madzi kapena zimalimbikitsa sodium kolorayidi amadzimadzi njira Lowani madzi gawo, ndiyeno kuyeza acidity mu njira amadzimadzi ndi alkali titration.Poyerekeza ndi njira zitatu zomwe tafotokozazi, zotsatira zake zimasonyeza kuti: Njira 1 ili ndi mphuno yakuthwa ya titration, ndipo imapewa kulakwitsa kwa mapeto a chiweruzo cha titration;Gwiritsani ntchito Njira 2 kuyesa Pakati pa zizindikiro zitatu, methyl red ili ndi kusintha kowoneka bwino kwa mtundu kumapeto kwa titration, ndipo zotsatira zake zimagwirizana ndi zotsatira zomwe zimatsimikiziridwa ndi njira ya potentiometric titration;mayeso a njira 3 akuwonetsa kuti kugwiritsa ntchito njira yothira sodium kolorayidi monga chotsitsa kumatha kusintha kwambiri kulekana Mogwira mtima, koma zotsatira zoyezera pambuyo pa kulekana ndizochepa, ndipo njira yogwiritsira ntchito njirayi ndi yayitali komanso yovuta.
