1,1,1,3,3,3-Hexafluoroisopropyl Methacrylate (iqiniswe ne-MEHQ)

I-Hexafluoroisopropyl methacrylate (HFIP-M) iwuketshezi olungenambala futhi olusobala, futhi ubumuncu bayo bunomthelela obalulekile kukhwalithi yalo.Indlela yokunquma i-acidity ye-hexafluoroisopropyl methacrylate iye yahlolwa ngokuhlolwa, futhi izindlela ezintathu zisetshenziswa Izindlela ezivame ukusetshenziswa ukuze kunqunywe i-acidity: 1) Sebenzisa indlela ye-potentiometric ukuze ubonise iphuzu lokugcina le-titration, futhi usebenzise i-potentiometer ezenzakalelayo ku-titration;2) Sebenzisa inkomba ukuze uhlole ngokubona iphuzu lokugcina le-titration;3) Okokuqala khipha i-asidi kusampula ngamanzi noma i-saturated sodium chloride aqueous solution Faka isigaba samanzi, bese ukala ubumuncu esixukwini esinamanzi nge-alkali titration.Uma kuqhathaniswa nezindlela ezintathu ezingenhla, imiphumela ibonisa ukuthi: Indlela yoku-1 inejika elibukhali le-titration, futhi igwema iphutha lokwahlulela kwephuzu lokugcina le-titration manual;Sebenzisa Indlela yesi-2 ukuhlola Phakathi kwezinkomba ezintathu, i-methyl ebomvu inokushintsha kombala okusobala kakhulu ekupheleni kwe-titration, futhi imiphumela ihambisana nemiphumela enqunywe indlela ye-potentiometric titration;ukuhlolwa kwendlela ye-3 kubonisa ukuthi ukusetshenziswa kwesisombululo se-sodium chloride egcwele njenge-extractant kungathuthukisa kakhulu ukuhlukaniswa Kuyasebenza, kodwa umphumela wokulinganisa ngemva kokuhlukana uphansi, futhi inqubo yokusebenza yale ndlela yinde futhi inzima.
