Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali C7H5FN2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

 

Imvelo:

-Ukubukeka: Impushana ecwebezelayo engenambala kuya emhlophe.

-Indawo yokuncibilika: mayelana nama-84-88 degrees Celsius.

-I-Solubility: Incibilika kuma-solvents amaningi e-organic, njenge-ethanol, i-ether ne-dimethyl sulfoxide.

 

Sebenzisa:

-Isetshenziswa ikakhulukazi emkhakheni we-organic synthesis, ingasetshenziswa njengama-intermediates kanye nama-reagents amakhemikhali.

-Ingasetshenziselwa ukuhlanganisa ezinye izinhlanganisela eziphilayo, njengezidakamizwa, izibulala-zinambuzane kanye nodayi.

 

Indlela Yokulungiselela:

Indlela yokulungiselela ayiyona inkimbinkimbi. Okulandelayo kuyindlela evamile yokulungiselela:

Ukusabela kwe-2-amino -4-chlorobenzonitrile ne-sodium fluoride ngaphansi kwe-catalysis ye-chloride yethusi kukhiqizwa. Izimo zokusabela ngokuvamile zenziwa ku-ethyl acetate, ngokuvamile futhi edinga ukushiswa kokusabela kanye nezinyathelo zenqubo ezifanele.

 

Ulwazi Lokuphepha:

-Inokuguquka okuphansi ngaphansi kwezimo ezijwayelekile zokusebenza. Kodwa-ke, njengekhemikhali, kusadingeka ukuhambisana nezinqubo eziyisisekelo zokuphepha zaselabhorethri.

-Le nhlanganisela ingase icasule amehlo nesikhumba. Kunconywa ukuthi ugqoke amagilavu ​​okuzivikela afanelekile kanye nezibuko ngesikhathi sokusetshenziswa.

-Ngesikhathi sokugcina nokuhamba, gwema ukuthintana nama-oxidants aqinile nama-acids aqinile ukuze uvimbele izingozi eziyingozi.

-Izinyathelo zosizo lokuqala: Uma uthinta isikhumba noma amehlo, geza ngokushesha ngamanzi amaningi. Uma udliwe noma uhogelwe, funa usizo lwezokwelapha ngokushesha.

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