Intshayelelo
I-4-Bromo-3-fluorotoluene yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
I-4-Bromo-3-fluorotoluene lulwelo olungenambala kunye nesakhiwo se-benzene ring kunye ne-bromine kunye ne-fluorine substituents. Inevumba elibi kwiqondo lobushushu begumbi. Ayinyibiliki kakuhle emanzini abandayo kodwa inokunyibilika kwizinyibilikisi zendalo.
Sebenzisa:
I-4-Bromo-3-fluorotoluene yinto ebalulekileyo ephakathi kwi-organic synthesis. Ikwasetyenziswa ngokuqhelekileyo kwintsimi yezinto eziphathekayo, umzekelo wokwenziwa kweepolymers ezineempawu ezizodwa.
Indlela:
Ukulungiswa kwe-4-bromo-3-fluorotoluene kufezekiswa ngokuphendula i-hydrogen fluoride (HF) kunye ne-hydrogen bromide (HBr) kunye ne-toluene-based based compounds kwi-reaction system. Oku kusabela kufuneka kuqhutywe kwiqondo lokushisa elifanelekileyo kunye noxinzelelo kunye nokusebenzisa i-catalyst ye-acidic.
Ulwazi ngoKhuseleko:
I-4-Bromo-3-fluorotoluene iyikhompawundi enetyhefu kwaye kufuneka igwenywe ekudibaneni ngokuthe ngqo nolusu, amehlo, kunye nephecana lokuphefumla. Xa zisetyenziswa, kufuneka kunxitywe izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglavu, isikhuselo sobuso. Xa uphatha le khompawundi, iinkqubo ezifanelekileyo zokusebenza zokhuseleko lwebhubhoratri kufuneka zilandelwe kwaye zisebenze kwindawo enomoya omhle. Kufuneka igcinwe kwindawo eyomileyo, epholileyo nengena umoya kakuhle, kude nemithombo yomlilo kunye namadangatye avulekileyo. Nawuphi na umsebenzi osetyenziswa kwikhompawundi kufuneka wenziwe ngezixhobo ezifanelekileyo kunye neemeko, ngoqeqesho olufanelekileyo kunye nabasebenzi abaqondayo ukusebenza ngokukhuselekileyo.
