Intshayelelo

I-Fluorobenzoyl chloride yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-p-fluorobenzoyl chloride:

 

Umgangatho:

- Imbonakalo: Ayinabala ukuya kulwelo olutyheli olukhanyayo.

- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ether, ikloroform kunye netoluene.

 

Sebenzisa:

- I-Fluorobenzoyl chloride ingasetyenziselwa njenge-reagent ebalulekileyo kwi-synthesis ye-organic compounds, kwaye isetyenziswa rhoqo kwi-reaction fluorination ye-esters kunye ne-ethers.

 

Indlela:

Indlela yokulungiselela i-fluorobenzoyl chloride ifumaneka ikakhulu ngokuphendula i-fluorobenzoic acid kunye ne-phosphorus pentachloride (PCl5). I-reaction equation imi ngolu hlobo lulandelayo:

C6H5COOH + PCl5 → C6H5COCl + POCl3 + HCl

 

Ulwazi ngoKhuseleko:

- I-Fluorobenzoyl chloride yinto enobungozi elungileyo, iyacaphukisa kwaye iyingozi. Izixhobo zokuzikhusela ezifana neeglavu zokhuselo, iiglasi zokhuselo kunye nempahla yokhuselo kufuneka zinxitywe xa zisetyenziswa.

• Kuphephe ukudibana nolusu, ukuphefumla iigesi okanye ulwelo olutshiziweyo.

- I-Flubenzoyl chloride kufuneka igcinwe kwindawo evaliweyo, eyomileyo, epholileyo, kude nomlilo kunye nezinto ezinokutsha.

 

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
