Intshayelelo
I-2-nitro-4-fluorobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Inkangeleko: 2-nitro-4-fluorobenzoic acid is a colorless or yellowish crystalline solid.
- Ukunyibilika: ukunyibilika kwezinye izinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-methylene chloride, i-soluble kancinane emanzini.
Sebenzisa:
- I-2-Nitro-4-fluorobenzoic acid idla ngokusetyenziswa njengendawo ephakathi kwi-organic synthesis ye-synthesis yezinye iikhompawundi.
Indlela:
- Ukulungiswa kwe-2-nitro-4-fluorobenzoic acid ngokuqhelekileyo kufumaneka nge-nitrification. Enye indlela enokwenzeka kukusabela kwi-2-bromo-4-fluorobenzoic acid kunye ne-nitric acid. Indlela yokusabela kufuneka idityaniswe neemeko ezifanelekileyo zokusabela kunye ne-catalysts.
Ulwazi ngoKhuseleko:
- I-2-Nitro-4-fluorobenzoic acid yi-organic compound enetyhefu kwaye iyacaphukisa. Ukuba sesichengeni okanye ukuphefumla iqondo eliphezulu leekhompawundi kunokuba yingozi empilweni.
- Amanyathelo afanelekileyo okhuseleko kufuneka athathwe xa uphatha, ukugcinwa kunye nokuphathwa, kubandakanywa nokunxiba iiglavu zokukhusela kunye neeglasi.
- Kulumkele ukudibana nee-oxidizing agents ezinamandla kunye nezixhobo ezinokutsha ukuthintela umlilo okanye ugqabhuko-dubulo.
