Intshayelelo
I-3-Bromo-4-fluorobenzaldehyde yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
- INkangeleko: 3-Bromo-4-fluorobenzaldehyde is a colorless to light yellow yellow solid or liquid.
- Ivumba: Inevumba elingaqhelekanga.
- Ukunyibilika: 3-Bromo-4-fluorobenzaldehyde iyanyibilika kwi-ethanol kunye ne-acetone, kodwa i-soluble encinci emanzini.
Sebenzisa:
- I-Chemical synthesis: I-3-bromo-4-fluorobenzaldehyde ingasetyenziselwa njengento ebalulekileyo ephakathi kwi-organic synthesis ukulungiselela ukulungiswa kwezinto ezahlukeneyo eziphilayo.
- Ezolimo: Ikhompawundi isetyenziswa njengesitshabalalisi kunye nesibulali zinambuzane kwezolimo kwaye ineziphumo ezilungileyo zokubulala izinambuzane kunye nokungunda.
Indlela:
- Ukulungiswa kwe-3-bromo-4-fluorobenzaldehyde ngokuqhelekileyo kuqhutyelwa yi-fluorination kunye ne-bromination reactions. Indlela eqhelekileyo kukusabela i-4-fluorobenzaldehyde kunye ne-bromine ukufumana imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
- I-3-Bromo-4-fluorobenzaldehyde yikhemikhali, nceda unakekele la manyathelo okhuseleko alandelayo xa uphatha kwaye ugcina:
- Kuphephe ukudibana nolusu kunye namehlo. Kwimeko yokudibanisa ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi;
- Kuphephe ukuphefumla umphunga okanye uthuli lwalo. Iimeko ezifanelekileyo zokungenisa umoya kufuneka zibonelelwe ngexesha lokusebenza;
- Kuphephe ukudibana nezinto ezinokutsha;
- Gcina kwindawo eyomileyo, epholileyo, kwindawo engenamoya;
- Nika ingqalelo kwizixhobo ezifanelekileyo zokuzikhusela (umzekelo, nxiba iliso elikhuselayo, iiglavu zokhuselo, njl.);
- Ukuba uziva ungonwabanga okanye uphefumle amanzi amaninzi, funa unyango ngokukhawuleza. Nceda ujonge kumaphepha edatha yokhuseleko afanelekileyo kunye nemithetho nemimiselo ngeenkcukacha ezithe vetshe.
