Isingeniso

I-3-Fluoro-4-nitrobenzoic acid iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C7H4FNO4. Okulandelayo yincazelo yezakhiwo ezithile, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwenhlanganisela:

 

Imvelo:

-Ukubukeka: Ikristalu elimhlophe noma eliphuzi kancane, noma okuphuzi ngokukhanyayo kuya kumpushana onsundu ngokuphuzi.

-Indawo yokuncibilika: 174-178 degrees Celsius.

-Indawo yokubilisa: 329 degrees Celsius.

-I-Solubility: I-Soluble ku-alcohol kanye nezincibilikisi eziphilayo, njenge-ethanol, i-dimethylformamide ne-dichloromethane.

 

Sebenzisa:

I-3-Fluoro-4-nitrobenzoic acid iyisithako esibalulekile esiphakathi, esisetshenziswa kabanzi emkhakheni we-organic synthesis.

-Ivame ukusetshenziswa ekuhlanganiseni kwezidakamizwa kanye nokuhlanganiswa kodayi.

-Le nhlanganisela ingasetshenziswa futhi njengento eluhlaza odayi, izibulala-zinambuzane neziqhumane.

 

Indlela Yokulungiselela:

Indlela yokulungiselela i-3-Fluoro-4-nitrobenzoic acid ngokuvamile ihlanganisa lezi zinyathelo ezilandelayo:

1. I-4-Nitrobenzoic acid isabela nge-hydrogen fluoride ukuze ithole i-3-nitro-4-fluorobenzoic acid.

2. Umkhiqizo otholwe esinyathelweni sangaphambilini usabela nge-sulfuric acid ukuze uthole i-3-Fluoro-4-nitrobenzoic acid.

 

Ulwazi Lokuphepha:

- I-3-Fluoro-4-nitrobenzoic acid ingase icasule amehlo, isikhumba, kanye nomgudu wokuphefumula. Naka ukusetshenziswa kwezinto zokuzivikela ngesikhathi sokuxhumana.

-Kufanele agcinwe esitsheni esimnyama, esomile futhi esivalekile, kude nomlilo kanye nama-oxidizing agents.

-Ekusetshenzisweni nasekuphathweni, kufanele kulandele izinqubo zokuphepha ezifanele, futhi kugcinwe umoya omuhle.
