Isingeniso

I-M-trifluoromethylphenol iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Amakristalu angenambala noma impushana ecwebezelayo emhlophe

- Ukunyibilika: kuncibilika kuzincibilikisi eziphilayo njenge-ethanol, i-ether, i-chloroform, njll., kuncibilika kancane emanzini.

 

Sebenzisa:

- I-M-trifluoromethylphenol ingasetshenziswa njengendawo ephakathi ku-organic synthesis ukuze kuhlanganiswe ezinye izinhlanganisela.

 

Indlela:

- Indlela evamile yokulungiselela ukwenza ukusabela kwe-nitrification eshisayo ku-toluene ukuze uthole i-3-nitromethylbenzene, bese ubuyisela elinye lamaqembu e-nitro nge-athomu ye-fluorine nge-fluorination.

 

Ulwazi Lokuphepha:

- I-M-trifluoromethylphenol iyinhlanganisela yemvelo ecasulayo futhi ingase ibangele ukucasuka emehlweni, isikhumba, kanye nomgudu wokuphefumula.

- Gqoka izinto zokuzivikela ezifanele, njengamagilavu ​​zelabhu, izibuko, namamaski okuzivikela, ngesikhathi sokuphatha noma sokuphatha.

- Gwema ukusabela okunobudlova ngama-oxidants aqinile, ama-asidi aqinile, ama-alkali aqinile, njll., ukuvimbela izimo eziyingozi.

- Naka ukungena komoya ngesikhathi sokusebenzisa futhi ugweme ukuhogela umhwamuko noma uthuli oluvela enkomponi.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
