Intshayelelo
I-1,3-Bis(trifluoromethyl)benzene yikhompawundi ephilayo. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala okanye oluqinileyo.
- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo, phantse ezinganyibiliki emanzini.
- Ubutyhefu: Inetyhefu ethile.
Sebenzisa:
I-1,3-Bis(trifluoromethyl)benzene inezicelo ezibalulekileyo kwi-organic synthesis:
- Njenge-reagent: isetyenziswa kwi-trifluoromethylation reactions kwi-organic synthesis reactions.
Indlela:
Kukho iindlela ezimbini eziphambili zokulungiselela i-1,3-bis(trifluoromethyl)benzene:
- I-Fluorination reaction: I-1,3-bis(trifluoromethyl)benzene ifunyenwe ngokusabela kwe-benzene kunye ne-trifluoromethane catalyzed yi-chromium chloride (CrCl3).
-Iodization reaction: I-1,3-bis(trifluoromethyl)benzene ilungiswa ngokusabela nge-trifluoromethane kubukho be-iodide yentsimbi (FeI2) nge-1,3-bis(iodomethyl)benzene.
Ulwazi ngoKhuseleko:
I-1,3-Bis(trifluoromethyl)benzene yikhompawundi ephilayo, kwaye la manyathelo okhuseleko alandelayo kufuneka athathelwe ingqalelo xa uyisebenzisa:
- Ubutyhefu: Ikhompawundi inetyhefu ethile kwaye kufuneka ithintelwe ekudibaneni nolusu, ukuphefumla, okanye ukungeniswa.
- Umngcipheko womlilo: I-1,3-bis(trifluoromethyl)benzene yinto enokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo namaqondo obushushu aphezulu, kwaye igcinwe kwindawo epholileyo, nengena umoya.
- Ukhuseleko lomntu: Iiglavu ezifanelekileyo zokukhusela, iiglasi kunye nempahla yokukhusela kufuneka ifakwe ngexesha lokusetyenziswa.
- Ukulahlwa kwenkunkuma: Xa kulahla inkunkuma, amanyathelo afanelekileyo kufuneka athathwe ukuze kuhlaziywe, kulungiswe okanye kulahlwe ngokukhuselekileyo ukuthintela ukungcoliseka kwendalo.
