Isingeniso
I-2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl, eyaziwa nangokuthi i-BTFMB, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-crystalline powder emhlophe
- Ayincibiliki emanzini, incibilika kancane ku-ether ne-benzene, incibilika kuzincibilikisi zemvelo ezifana notshwala
Sebenzisa:
- I-2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl iyingxenye ebalulekile ye-organic, esetshenziswa kakhulu ekuhlanganiseni kwe-polymer compounds nama-polymers
- Ingasetshenziselwa ukulungisa ama-polymers ngokuzinza kokushisa okuphezulu, izakhiwo ezinhle kakhulu zikagesi nezemishini, njenge-polyimide, i-polyetherketone, njll.
- I-BTFMB ingasetshenziswa futhi njengento eluhlaza yama-catalysts, izithasiselo zokugqoka, izinto ze-electrochemical, njll.
Indlela:
- Ukuhlanganiswa kwe-2,2′-bis(trifluoromethyl)-4,4′-diaminobiphenyl ngokuvamile kuhamba ngokusabela okuyizinyathelo eziningi
- Indlela ethile ihlanganisa i-hydroxymethylation ye-methacrylonitrile ne-4,4'-diaminobiphenyl ukuze uthole umkhiqizo ophakathi, olandelwa yi-trifluoromethylation ukuze uthole umkhiqizo ohlosiwe.
Ulwazi Lokuphepha:
- 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl ingxube yemvelo engase ibe nobuthi futhi icunule.
- Ngesikhathi sokusetshenziswa nokugcinwa, ukuthintana nama-oxidizing agents aqinile nama-acids aqinile kufanele kugwenywe
- Lapho uphatha futhi ulahla imfucuza, thobela imithetho nezimiso zendawo
