Isingeniso

I-2-Chlorotrifluorotoluene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

Ukubukeka: I-2-chlorotrifluorotoluene uketshezi olungenambala noma ikristalu emhlophe.

Ukuminyana: Ukuminyana okuhlobene kuphezulu.

Ukunyibilika: Kuncibilika kuzincibilikisi eziphilayo, njengotshwala nama-ether, ezingeni lokushisa legumbi.

 

Sebenzisa:

I-2-Chlorotrifluorotoluene isetshenziswa kabanzi ku-organic synthesis futhi ingasetshenziswa njenge-catalyst, reaction intermediate noma i-solvent.

 

Indlela:

Izindlela zokulungiselela ze-2-chlorotrifluorotoluene ngokuvamile zimi kanje:

Itholakala ngokusabela kwe-trifluorotoluene ne-aluminium chloride, futhi izimo zokusabela ziqinile.

Ukusabela kwe-trifluorotoluene ngegesi ye-chlorine kudinga ukwenziwa ekushiseni okuphezulu.

Ingase futhi itholakale ngokusabela kwe-3-fluorophenylacetic acid ngezinsimbi ze-alkali noma izisekelo eziphilayo, kulandelwa ukusabela nge-aluminium chloride.

 

Ulwazi Lokuphepha:

Lapho uphatha i-2-chlorotrifluorotoluene, kufanele kuqashelwe ukugwema ukuthintana nesikhumba namehlo ukugwema ukucasuka noma ukugqwala.

Kufanele isetshenziswe endaweni enomoya omuhle ukuze kugwenywe ukuhogela umhwamuko noma uthuli.

Lapho ugcina futhi uthutha, kufanele kuqashelwe ukuvimbela ukushisa okuphezulu kanye nemithombo yomlilo.

Lapho silahla imfucuza, kufanele silandele imithetho nezimiso zemvelo yendawo futhi sithathe izinyathelo ezifanele zokuyilahla.

 

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