Isingeniso

I-Fluorobenzoyl chloride iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-p-fluorobenzoyl chloride:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala oluphuzi olukhanyayo.

- Ukunyibilika: Kuncibilika kuzincibilikisi eziphilayo njenge-ether, i-chloroform ne-toluene.

 

Sebenzisa:

- I-Fluorobenzoyl chloride ingasetshenziswa njenge-reagent ebalulekile ekuhlanganiseni kwezinto eziphilayo, futhi ivame ukusetshenziswa ekuphenduleni kwe-fluorination yama-ester nama-ether.

 

Indlela:

Indlela yokulungiselela i-fluorobenzoyl chloride itholakala ikakhulukazi ngokuphendula i-fluorobenzoic acid ne-phosphorus pentachloride (PCl5). I-reaction equation imi kanje:

C6H5COOH + PCl5 → C6H5COCl + POCl3 + HCl

 

Ulwazi Lokuphepha:

- I-Fluorobenzoyl chloride iyinhle eyingozi, iyacika futhi iyagqwala. Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko zokuzivikela nezingubo zokuzivikela kufanele zigqokwe lapho zisetshenziswa.

- Gwema ukuthinta isikhumba, ukuhogela amagesi noma uketshezi olufafaziwe.

- I-Flubenzoyl chloride kufanele igcinwe endaweni evalekile, eyomile, epholile, kude nomlilo nezinto ezivuthayo.
