Isingeniso

I-2,5-Dichloronitrobenzene iyinhlanganisela yezinto eziphilayo. Kuyikristalu engenambala ukuya kophuzi ngokuphaphathekile enephunga elibabayo nelihlabayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,5-dichloronitrobenzene:

 

Ikhwalithi:

- Ukubukeka: Angenambala amakristalu aphuzi

- Ukunyibilika: Kuncibilika kancane emanzini futhi kuncibilika kalula kuzincibilikisi zemvelo ezifana notshwala nama-ether

 

Sebenzisa:

- I-2,5-Dichloronitrobenzene ivame ukusetshenziswa njengento yokuqala ye-organic synthesis kuma-laboratories amakhemikhali futhi ingasetshenziswa ukulungisa ezinye izinhlanganisela eziphilayo.

 

Indlela:

- I-2,5-dichloronitrobenzene ivamise ukulungiswa ngokusabela okuxubile kwe-nitrification ye-nitrobenzene.

- Elabhorethri, i-nitrobenzene ingafakwa i-nitrate kusetshenziswa ingxube ye-nitric acid ne-nitrous acid ukunikeza ukusabela kwe-2,5-dichloronitrobenzene.

 

Ulwazi Lokuphepha:

- I-2,5-dichloronitrobenzene iwubuthi, futhi ukuchayeka kanye nokuhogela iphunga layo kungaba yingozi empilweni. Gwema ukuthintana ngqo nesikhumba, amehlo, nomgudu wokuphefumula.

- Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko, namamaski kufanele zigqokwe lapho uphatha futhi uphatha i-2,5-dichloronitrobenzene.

- Kufanele isetshenziswe endaweni enomoya omuhle ukugwema ukuhogela umhwamuko.

- Imfucuza kufanele ilahlwe ngokuhambisana nemithetho yendawo futhi akufanele ilahlwe.

 

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