Mokhoa oa Sehlahisoa:
E fumanoa ka karabelo ea ethylenediamine ka chloroacetic acid, kapa karabelo ea ethylenediamine ka formaldehyde le sodium cyanide.
Likaroloana:
EDTA 4NA ke phofo e tšoeu ea kristale e na le metsi a 4 a kristale, a qhibilihang habonolo ka metsing, tharollo e nang le metsi ke alkaline, e qhibilihang hanyenyane ka har'a li-solvents tse kang ethanol, e ka lahleheloa ke karolo kapa metsi 'ohle a kristale ka mocheso o phahameng.
Lisebelisoa:
EDTA 4NA ke chelator ea tšepe ea tšepe e sebelisoang haholo.
1. E ka sebelisoa indastering ea masela bakeng sa ho daea, ho ntlafatsa mebala, ho ntlafatsa 'mala le ho khanya ha masela a dailoeng.
2. E sebelisoa e le addititive, activator, metal ion masking agent le activator indastering ea rabara ea butadiene.
3. E ka sebelisoa indastering ea acrylic e omeletseng ho felisa tšitiso ea tšepe.
4. EDTA 4NA e ka boela ea sebelisoa ka sesepa sa metsi ho ntlafatsa boleng ba ho hlatsoa le phello ea ho hlatsoa.
5. E sebelisoa e le setlolo sa metsi, se hloekisang metsi, se sebelisetsoang ho hloekisa boleng ba metsi.
6. E sebelisoa e le catalyst ea maiketsetso ea rabara, acrylic polymerization terminator, khatiso le lisebelisoa tsa ho daea, joalo-joalo.
7. E boetse e sebelisoa bakeng sa titration tlhahlobo ea lik'hemik'hale, 'me ka nepo e ka titrate mefuta e sa tšoaneng ea li-ion tsa tšepe.
8. Ho phaella litšebelisong tse ka holimo, EDTA 4NA e ka boela ea sebelisoa meriana, lik'hemik'hale tsa letsatsi le letsatsi, ho etsa pampiri le liindasteri tse ling.
