| Iikhowudi zoMngcipheko | I-R22 – Iyingozi xa iginyiwe I-R45 – Isenokubangela umhlaza R50/53 – Ityhefu kakhulu kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. R36 – Iyandicaphukisa emehlweni I-R25 – Inetyhefu xa iginyiwe R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. |
| Inkcazelo yoKhuseleko | S22 – Musa ukuphefumla uthuli. S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S37 – Nxiba iiglavu ezifanelekileyo. |

Intshayelelo
I-2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl, eyaziwa ngokuba yi-BTFMB, yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Umgubo omhlophe wekristale
-Ayinyibiliki emanzini, ayinyibiliki kancinane kwi-ether kunye nebenzene, inyibilika kwizinyibilikisi zendalo ezifana neealkoholi.
Sebenzisa:
- 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl yinto ebalulekileyo ye-organic intermediate, isetyenziswa ikakhulu ekudityanisweni kweekhompawundi zepolymer kunye neepolima
- Ingasetyenziselwa ukulungiselela iipolymers kunye nozinzo oluphezulu lobushushu, iimpawu ezibalaseleyo zombane kunye nezomatshini, njenge-polyimide, i-polyetherketone, njl.
-I-BTFMB inokusetyenziswa njengesixhobo ekrwada kwi-catalysts, izongezo zokwaleka, izinto ze-electrochemical, njl.
Indlela:
-I-synthesis ye-2,2′-bis(trifluoromethyl)-4,4′-diaminobiphenyl ngokubanzi ihamba ngeendlela ezininzi zokusabela
- Indlela ethile ibandakanya i-hydroxymethylation ye-methacrylonitrile kunye ne-4,4'-diaminobiphenyl ukufumana imveliso ephakathi, ilandelwa yi-trifluoromethylation ukufumana imveliso ejoliswe kuyo.
Ulwazi ngoKhuseleko:
- 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl yi-organic compound enokuba yityhefu kwaye iyacaphukisa.
- Ngexesha lokusetyenziswa kunye nokugcinwa, ukudibanisa kunye ne-oxidizing agents ezinamandla kunye ne-acids eqinile kufuneka kugwenywe
- Xa uphatha kwaye ulahla inkunkuma, thobela imithetho kunye nemimiselo yendawo
