Intshayelelo
I-3,4-Difluorobsyl bromide yi-organic compound kunye ne-chemical formula C7H5BrF2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
- 3,4-Difluorobenzyl bromide lulwelo olungenambala.
-Inoxinano lwe 1.78g/cm³ kunye neqondo lokubila lika 216-218 degrees celcius.
-Kubushushu begumbi, inokuchithwa kwii-solvents eziphilayo ezifana ne-ether kunye ne-chloroform.
Sebenzisa:
- 3,4-Difluorobenzyl bromide isoloko isetyenziswa njenge-reagent kwi-organic synthesis. Ingasetyenziselwa ukudibanisa i-organic compounds kunye nezakhiwo ezithile kunye neempawu.
-Isenokusetyenziswa njengendawo ephakathi kumayeza kunye nezitshabalalisi.
Indlela yokulungiselela:
Ukulungiswa kwe-3,4-Difluorobenzyl bromide inokufumaneka ngokuphendula i-3,4-difluorobenzaldehyde kunye ne-sodium bromide phantsi kweemeko ezifanelekileyo zokuphendula.
Ulwazi ngoKhuseleko:
- I-3,4-i-bromide ye-Difluorobenzyl idinga ingqalelo kwimilinganiselo yokukhusela ngexesha lokugcinwa kunye nokuphatha.
-Kufuneka igcinwe kwisitya esivaliweyo, ugweme ukudibanisa nomoya kunye nomswakama.
-Nxiba iiglavu ezifanelekileyo zokukhusela kunye neeglasi xa usebenzisa.
-Kuphephe ukuphefumla, ukuhlafuna okanye ukubamba ulusu ngexesha lokusebenza.
-Xa ulahla inkunkuma, kufuneka iphathwe kwaye ilahlwe ngokuhambelana nemimiselo yelizwe kunye neyengingqi efanelekileyo.
Nceda uqinisekise ukuba iinkqubo ezifanelekileyo zokhuseleko zilandelwa ngokungqongqo xa usebenzisa le khompawundi, kwaye amanyathelo afanelekileyo okukhusela athathwa ngokwemeko ethile. Ukuba uneminye imibuzo yokusebenza, nceda uqhagamshelane neengcali okanye isikhokelo esifanelekileyo selabhoratri ye-organic chemistry.
