Intshayelelo
I-2-Fluoro-4-bromobenzaldehyde i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
- INkangeleko: 2-Fluoro-4-bromobenzaldehyde is a colorless to yellowish solid.
- Ukunyibilika: Inyibilika kwezinye izinyibilikisi zepolar ezifana ne-ethanol kunye ne-methylene chloride.
- Ukuzinza: I-2-Fluoro-4-bromobenzaldehyde yikhompawundi engazinzanga echaphazeleka ngokulula ngokukhanya kunye nobushushu kwaye inokuchithwa ngokulula ngokufudumeza.
Sebenzisa:
- Isenokusetyenziswa kwiindawo ezifana nedayi synthesis, catalysts, kunye nezinto ezibonakalayo.
Indlela:
I-2-Fluoro-4-bromobenzaldehyde inokwenziwa ngeendlela ezahlukeneyo, ezifana:
I-2-bromo-4-fluorobenzyl yotywala inokuphendulwa ngesisombululo se-acidic, isisombululo sokuphendula sinokungathinteki kwaye sihlanjululwe ukufumana imveliso ecocekileyo.
Inokufumaneka kwakhona nge-oxidizing 4-fluorostyrene phambi kwe-ethyl bromide.
Ulwazi ngoKhuseleko:
I-2-Fluoro-4-bromobenzaldehyde yikhompawundi ephilayo efuna iinkqubo ezifanelekileyo zokhuseleko kunye nemilinganiselo ekufuneka ithotyelwe:
- I-2-Fluoro-4-bromobenzaldehyde iyacaphukisa kwaye inokubangela umonakalo emehlweni, ulusu, kunye nendlela yokuphefumla. Xa usebenza, kuyimfuneko ukunxiba izixhobo ezifanelekileyo zokukhusela ezinjengeeglasi, iiglavu kunye nemaski.
- Kuphephe ukuphefumla umphunga kwiigesi okanye izinyibiliko zazo. Oonogada bafanele baqhutywe okanye basetyenziswe kwindawo enomoya owaneleyo.
• Kuphephe ukuchanabeka elangeni okanye kubushushu. Kufuneka igcinwe kwindawo epholileyo, eyomileyo ukuze ugweme ukudibanisa nee-oxidants.
- Musa ukuxuba i-2-fluoro-4-bromobenzaldehyde kunye nee-oxidizing agents ezinamandla kwaye musa ukukhupha emanzini okanye kwezinye iindawo.
Ngaphambi kokusebenzisa i-2-fluoro-4-bromobenzaldehyde, qinisekisa ukuba ufunda kwaye uyawaqonda amaxwebhu afanelekileyo edatha yokhuseleko kunye neencwadi zokusebenza, kwaye ulandele ukuphatha ngokufanelekileyo kunye neendlela zokulahla.
