Isingeniso

I-2,4-I-Dichlorotrifluorotoluene iyinhlanganisela yezinto eziphilayo.

 

I-2,4-dichlorotrifluorotoluene isetshenziswa ngokuyinhloko njenge-solvent ekuphenduleni kwe-organic synthesis, futhi ingasetshenziswa njenge-solvent yokusabela, i-solvent ye-fluorinating reagents kanye ne-solvent yama-catalysts.

 

Indlela yokulungisa ivamise ukuthi i-2,4-dichlorotrifluorotoluene ingatholwa nge-fluorination ye-benzene. Indlela ethize yokulungiselela imi kanje: i-benzene ne-hydrofluoric acid isabela ku-reactor, bese kwengezwa igesi ye-chlorine, izimo zokusabela zilawulwa ukusabela kwe-fluorination, futhi ekugcineni i-2,4-dichlorotrifluorotoluene ehlanzekile itholakala ngokuhlukana, ukuhlanzwa nezinye izinyathelo. .

 

Kuyadingeka ukulandela ngokuqinile izinqubo zokuphatha eziphephile zamakhemikhali futhi ugqoke izinto zokuzivikela ezifanele njengezibuko zokuphepha, amagilavu ​​nezingubo zokuzivikela;

Gwema ukuthintana ngqo nesikhumba, amehlo kanye nomgudu wokuphefumula, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha uma wenza;

Gwema ukuthinta izinto ezivuthayo futhi ugweme ukusabela okukhiqiza amagesi anobuthi;

Sebenzisa endaweni engenawo umoya ukuze ugweme ukuhogela amagesi anobuthi;

Lapho igcinwa, kufanele igcinwe kude nomlilo kanye namazinga okushisa aphezulu, futhi igcinwe endaweni epholile, eyomile.

  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
