Mawu Oyamba
2,2'-Bis(trifluoromethyl) -4,4'-diaminobiphenyl, yomwe imadziwikanso kuti BTFMB, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: ufa woyera wa crystalline
- Sasungunuke m'madzi, sungunuka pang'ono mu ether ndi benzene, sungunuka mu zosungunulira organic monga ma alcohols
Gwiritsani ntchito:
- 2,2'-Bis(trifluoromethyl) -4,4'-diaminobiphenyl ndi yofunika organic wapakatikati, makamaka ntchito synthesis wa polima mankhwala ndi ma polima
- Itha kugwiritsidwa ntchito pokonzekera ma polima okhala ndi kukhazikika kwa kutentha kwambiri, zinthu zabwino kwambiri zamagetsi ndi zamakina, monga polyimide, polyetherketone, etc.
- BTFMB itha kugwiritsidwanso ntchito ngati zopangira zopangira, zowonjezera zokutira, zida zamagetsi, ndi zina zambiri.
Njira:
- Kaphatikizidwe ka 2,2'-bis(trifluoromethyl) -4,4'-diaminobiphenyl nthawi zambiri amadutsa munjira zingapo
- Njira yeniyeni imaphatikizapo hydroxymethylation ya methacrylonitrile ndi 4,4'-diaminobiphenyl kuti apeze mankhwala apakatikati, otsatiridwa ndi trifluoromethylation kuti apeze mankhwala omwe akufuna.
Zambiri Zachitetezo:
- 2,2'-Bis(trifluoromethyl) -4,4'-diaminobiphenyl ndi organic pawiri kuti akhoza kukhala poizoni ndi zokwiyitsa.
- Pogwiritsa ntchito ndi kusunga, kukhudzana ndi oxidizing amphamvu ndi ma asidi amphamvu kuyenera kupewedwa
- Pogwira ndi kutaya zinyalala, tsatirani malamulo ndi malamulo amderalo
