Isingeniso
I-4-Bromo-3-fluorotoluene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-4-Bromo-3-fluorotoluene iwuketshezi olungenambala olunesakhiwo sendandatho ye-benzene kanye ne-bromine ne-fluorine esikhundleni. Inephunga elimnandi ekamelweni lokushisa. Ayincibiliki kahle emanzini abandayo kodwa ingancibilika kuzincibilikisi zemvelo.
Sebenzisa:
I-4-Bromo-3-fluorotoluene iyingxenye ebalulekile ye-organic synthesis. Ibuye isetshenziswe ngokujwayelekile emkhakheni wezinto zokwakha, isibonelo ukuhlanganiswa kwama-polymers anezakhiwo ezikhethekile.
Indlela:
Ukulungiswa kwe-4-bromo-3-fluorotoluene kufinyelelwa ngokuphendula i-hydrogen fluoride (HF) ne-hydrogen bromide (HBr) ngezinhlanganisela ezifanele ezisekelwe ku-toluene ohlelweni lokusabela. Lokhu kusabela kudinga ukwenziwa ngezinga lokushisa elifanele kanye nokucindezela futhi kusetshenziswa i-acidic catalyst.
Ulwazi Lokuphepha:
I-4-Bromo-3-fluorotoluene iyinhlanganisela enobuthi futhi kufanele igwenywe ukuthintana ngqo nesikhumba, amehlo, nendlela yokuphefumula. Lapho isetshenziswa, izinto zokuzivikela ezifanele njengamagilavu, izibuko, nesivikelo sobuso kufanele kugqokwe. Lapho uphatha le nhlanganisela, izinqubo ezifanele zokusebenza zokuphepha kwelabhorethri kufanele zilandelwe futhi zisetshenziswe endaweni enomoya omuhle. Kufanele igcinwe endaweni eyomile, epholile futhi enomoya omuhle, kude nemithombo yomlilo kanye namalangabi avulekile. Noma yikuphi ukuhlinzwa kusetshenziswa inhlanganisela kufanele kwenziwe ngemishini nemibandela efanele, ngokuqeqeshwa okufanele kanye nabasebenzi abakuqondayo ukusebenza okuphephile.
