Folasaga
2,2′-Bis(trifluoromethyl) -4,4′-diaminobiphenyl, e taʻua foʻi o le BTFMB, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:
Tulaga lelei:
- Fa'aaliga: Pa'epa'e tioata pa'epa'e
- E le mafai ona solu i le vai, e mafai ona solu i le ether ma le benzene, e mafai ona solu i solu fa'aletino pei ole ava malosi.
Fa'aaogā:
- 2,2'-Bis (trifluoromethyl) -4,4'-diaminobiphenyl o se mea taua faʻale-aganuʻu, e masani ona faʻaaogaina i le tuʻufaʻatasia o polymer compounds ma polymers.
- E mafai ona faʻaaogaina e saunia ai polymers ma le maualuga o le vevela, sili atu le eletise ma mea faʻainisinia, pei ole polyimide, polyetherketone, ma isi.
- BTFMB e mafai foi ona faʻaaogaina e avea o se mea mataʻutia mo catalysts, faʻapipiʻi faʻapipiʻi, mea eletise, ma isi.
Metotia:
- O le tuʻufaʻatasiga o le 2,2′-bis(trifluoromethyl) -4,4′-diaminobiphenyl e masani ona alu i le tele o laʻasaga tali.
- O le auala faʻapitoa e aofia ai le hydroxymethylation o le methacrylonitrile ma le 4,4′-diaminobiphenyl e maua ai se oloa vavalalata, sosoo ai ma le trifluoromethylation e maua ai le oloa faʻatatau.
Fa'amatalaga Saogalemu:
- 2,2'-Bis(trifluoromethyl) -4,4'-diaminobiphenyl o se faʻalapotopotoga faʻapitoa e ono oona ma faʻafefe.
- A'o fa'aoga ma teuina, e tatau ona 'alofia le fa'afeso'ota'i ma vaila'au fa'ama'i malolosi ma vaila'au malolosi
- Pe a tagofia ma lafoai otaota, tausisia tulafono ma tulafono faatonutonu a le lotoifale
