Intshayelelo
I-2-Chloro-4-fluorobenzyl bromide yi-organic compound ene-chemical formula C7H5BrClF. Lulwelo olunamafutha angenambala okanye olukhanyayo kubushushu begumbi. Oku kulandelayo yinkcazo yendalo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwe-bromide ye-2-Chloro-4-fluorobenzyl:
Indalo:
-Imbonakalo: ulwelo olunamafutha angenambala okanye olumthubi
-Ukunyibilika: Inyibilika kancinci emanzini, inyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-dichloromethane
-Indawo yokunyibilika:-10°C
-Indawo yokuBilisa: 112-114°C
-Ubuninzi: 1.646 g/mL
Sebenzisa:
I-2-Chloro-4-fluorobenzyl bromide isoloko isetyenziswa njengento ebalulekileyo ephakathi kunye nekrwada kwi-organic synthesis. Ingasetyenziselwa ukuhlanganiswa kwezinye izinto eziphilayo, ezifana ne-heterocyclic compounds, iziyobisi kunye nedayi.
Indlela yokulungiselela:
I-2-Chloro-4-fluorobenzyl bromide inokulungiswa ngokuphendula i-2-chloro-4-fluorobenzyl utywala kunye ne-hydrogen bromide. Okokuqala, i-2-chloro-4-fluorobenzyl utywala i-esterified kunye ne-hydrogen bromide phambi kwesiseko sokuvelisa i-2-chloro-4-fluorobenzyl bromide. Emva koko, yahlanjululwa ngokukhutshwa kunye ne-hydrochloric acid egxininisiweyo kunye ne-distillation ukufumana imveliso ekujoliswe kuyo 2-Chloro-4-fluorobenzyl bromide.
Ulwazi ngoKhuseleko:
La manyathelo okhuseleko alandelayo kufuneka aqwalaselwe xa usebenzisa okanye uphethe i-2-Chloro-4-fluorobenzyl bromide:
-Kuphephe ukudibana nolusu, amehlo kunye nenwebu. Kwimeko yoqhagamshelwano, gubha ngamanzi amaninzi kwaye ufune unyango.
-Ngexesha lokusebenza, sebenzisa izixhobo ezifanelekileyo zokukhusela, ezifana neeglavu zokukhusela, iiglasi zokukhusela kunye nempahla yokukhusela.
-Kuphephe ukuphefumla umphunga okanye uthuli lwalo. Ngexesha lokusebenza, kufuneka kuqinisekiswe ukuba ikwindawo enomoya.
-Ukugcinwa kufuneka kutywinwe ukuphepha ukudibanisa ne-oxidants kunye ne-acids eqinile / i-alkalis.
