Nhanganyaya
2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl, inozivikanwawo seBTFMB, inhengo yemubatanidzwa. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
- Kuonekwa: White crystalline powder
-Isinganyungudika mumvura, inonyungudika zvishoma muether uye benzene, inonyungudika muorganic solvents senge madoro
Shandisa:
- 2,2'-Bis(trifluoromethyl) -4,4′-diaminobiphenyl yakakosha yepakati pepakati, inonyanya kushandiswa mukugadzirwa kwepolymer komisheni nemapolima.
- Inogona kushandiswa kugadzira mapolymer ane yakanyanya kugadzikana tembiricha, yakanakisa magetsi uye michina zvivakwa, senge polyimide, polyetherketone, nezvimwe.
- BTFMB inogona zvakare kushandiswa seyakagadzirwa zvinhu zvinokonzeresa, coating additives, electrochemical zvinhu, nezvimwe.
Nzira:
- Iyo synthesis ye2,2'-bis(trifluoromethyl) -4,4'-diaminobiphenyl inowanzoenda kuburikidza neakawanda-nhanho kuita.
- Iyo chaiyo nzira inosanganisira hydroxymethylation ye methacrylonitrile ne 4,4'-diaminobiphenyl kuti iwane chigadzirwa chepakati, ichiteverwa ne trifluoromethylation kuti iwane chinangwa chigadzirwa.
Zvekuchengetedza
- 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl is an organic compound inogona kuva chepfu uye inogumbura.
- Panguva yekushandiswa nekuchengetedza, kusangana neakasimba oxidizing agents uye yakasimba acids inofanira kudziviswa
- Pakubata nekurasa tsvina, tevedzera mitemo nemirairo yenzvimbo
