Intshayelelo

Yikhompawundi ephilayo ene-chemical formula C7H5FN2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

 

Indalo:

-Imbonakalo: Ayinambala ukuya kumgubo omhlophe wekristale.

-Indawo yokunyibilika: malunga ne-84-88 degrees Celsius.

-I-Solubility: I-soluble kwi-solvents ezininzi zezinto eziphilayo, ezifana ne-ethanol, i-ether kunye ne-dimethyl sulfoxide.

 

Sebenzisa:

-isetyenziswa ikakhulu kwintsimi ye-organic synthesis, ingasetyenziselwa njenge-intermediates kunye ne-reagents yeekhemikhali.

-Ingasetyenziselwa ukudibanisa ezinye izinto eziphilayo, ezifana neziyobisi, i-pesticides kunye nedayi.

 

Indlela yokulungiselela:

Indlela yokulungiselela ayinzima. Oku kulandelayo yindlela eqhelekileyo yokulungiselela:

Ukusabela kwe-2-amino -4-chlorobenzonitrile kunye ne-sodium fluoride phantsi kwe-catalysis ye-chloride yobhedu yenziwa. Iimeko zokusabela ziqhutyelwa ngokubanzi kwi-ethyl acetate, ngokuqhelekileyo ifuna ukufudumeza ukuphendula kunye namanyathelo afanelekileyo enkqubo.

 

Ulwazi ngoKhuseleko:

-Inokuguquka okuphantsi phantsi kweemeko eziqhelekileyo zokusebenza. Nangona kunjalo, njengento yeekhemikhali, kusafuneka ukuthobela iinkqubo ezisisiseko zokhuseleko lwebhubhoratri.

-Le khompawundi inokucaphukisa amehlo kunye nolusu. Kunconywa ukuba unxibe iiglavu ezifanelekileyo zokukhusela kunye neeglasi ngexesha lokusetyenziswa.

-Ngexesha lokugcinwa kunye nokuthutha, thintela ukudibanisa ne-oxidants eqinile kunye ne-acids eqinile ukukhusela izingozi ezinobungozi.

-Amanyathelo oncedo lokuqala: Ukuba udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi. Ukuba ungenile okanye urholile, funa uncedo lwezonyango ngokukhawuleza.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
