4,4′-DIAMINOBIPHENYL-2,2′-DICARBOXYLIC ACID cas:17557-76-5

Incazelo emfushane:

I-4,4'-diaminobiphenyl-2,2'-dicarboxylic acid, eyaziwa nangokuthi i-DABDA, iyinhlanganisela yamakhemikhali ene-molecular formula C16H14N2O4.I-white crystalline powder encibilika kakhulu kuzincibilikisi zemvelo ezifana ne-ethanol, i-acetone, ne-methanol.I-DABDA inezinto zamakhemikhali ezihlukile eziyenza ifanelekele ubuningi bezicelo.

Le nhlanganisela yamakhemikhali ithola ukusetshenziswa okubanzi emkhakheni wokucwaninga nokuthuthukiswa kwe-polymer.Ngenxa yokuqina kwayo okushisayo okuphezulu kanye nezakhiwo ezinhle zemishini, i-DABDA ivame ukusetshenziswa njengebhlokhi yokwakha ekuhlanganisweni kwama-polymers athuthukile.Lawa ma-polymer anezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi okokunamathela, okokunamathelisa, nezivikeli zikagesi.

Ngaphezu kwalokho, i-DABDA ikhombisa izakhiwo ezinhle kakhulu ze-electrochemical, iyenza ibe yikhandidethi elifanele lokuthuthukiswa kwamadivayisi kagesi asebenza kahle kakhulu.Isetshenziswa kabanzi ekwenzeni ama-electrode ama-supercapacitor namabhethri e-lithium-ion.Ngokusebenza kwayo okukhethekile nokuzinza, i-DABDA inikela ekusebenzeni okuphelele nasekuphileni kwalezi zinhlelo zokugcina amandla.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-4,4'-diaminobiphenyl-2,2'-dicarboxylic acid yethu ikhiqizwa ngokucophelela ukuze kuqinisekiswe izinga eliphezulu lokuhlanzeka nekhwalithi.Iqoqo ngalinye lihlolwa kanzima futhi lihlaziywe ukuze lihambisane namazinga omhlaba.Siyaziqhenya ngokuletha umkhiqizo oweqa okulindelwe ngamakhasimende futhi ohlangabezana nezidingo zezimboni ezahlukahlukene.

Imiyalo yokuphepha nokuphatha:

- Gwema ukuthintana ngqo kwesikhumba kanye nokuhogela uthuli noma umhwamuko.Izinto zokuzivikela ezifanele kufanele zigqokwe lapho kusingathwa lesi sithako.

- Gcina endaweni epholile neyomile kude nelanga eliqondile nezinto ezingahambelani.

- Landela izinqubo ezifanele zokulahla ngokuhambisana nemithetho yendawo.
