Intshayelelo
I-2,5-Bis(trifluoromethyl)bromobenzene yikhompawundi ephilayo. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 2,5-Bis(trifluoromethyl)bromobenzene lulwelo olungenambala.
- Ukunyibilika: I-2,5-bis (trifluoromethyl) i-bromobenzene i-soluble kwi-polar organic solvents njenge-ethanol, i-dimethylformamide, njl.
- Uzinzo: Ikhompawundi izinzile kubushushu begumbi, kodwa ifuna ukukhuselwa ekukhanyeni kwelanga.
Sebenzisa:
- I-2,5-Bis (trifluoromethyl) i-bromobenzene yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye isoloko isetyenziswa kwi-organic synthesis reactions.
- Ingasetyenziswa njengemathiriyeli ekrwada yamayeza okubulala izinambuzane, imichiza yokungunda, nemichiza yokungunda.
- Ikhompawundi inokusetyenziswa kwakhona kwimimandla yombane kunye neekhemikhali.
Indlela:
Ukulungiswa kwe-2,5-bis(trifluoromethyl)bromobenzene idla ngokuqhutywa ngala manyathelo alandelayo:
1. Ukusabela kwe-2,5-diiodomethylbenzene kunye ne-trifluoromethyl bromide kwi-solvent ye-organic.
2. Imveliso elungiselelwe i-crystallized, ihlungwe kwaye yomiswe ukufumana imveliso ecocekileyo.
Ulwazi ngoKhuseleko:
- 2,5-Bis(trifluoromethyl)bromobenzene inefuthe elicaphukisayo emehlweni kunye nolusu, kwaye kufuneka kuthathwe amanyathelo okhuseleko xa uyisebenzisa.
- Xa uphethe kwaye ugcina, kunqande ukunxibelelana nee-oxidants kunye neealkali ezinamandla ukunqanda ukuphendula okuyingozi.
- Iimeko ezifanelekileyo zokungenisa umoya kufuneka zigcinwe ngexesha lokusetyenziswa.
- Kwimeko yokuchaphazeleka ngempazamo okanye ukuphefumla kwikhompawundi, funa unyango olukhawulezileyo. Ukuba kukho imfuneko, yiza nephepha ledatha yokhuseleko kwikhompawundi kwireferensi kagqirha wakho.
