Intshayelelo
Yikhompawundi ephilayo enefomula yeekhemikhali yi-C5H2ClFN2O2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: Umgubo oqinileyo omhlophe ukuya kumthubi.
-Indawo yokunyibilika: Indawo enyibilikayo yekhompawundi imalunga ne-160-165 degrees Celsius.
-I-Solubility: Inokuchithwa kwii-solvents eziphilayo ezifana ne-dimethylphosphinate kunye ne-dimethylformamide, kodwa ukunyibilika kwayo emanzini kuphantsi.
Sebenzisa:
-Olunye lolona setyenziso luphambili lwesibulali-zinambuzane sisibulali zinambuzane kunye nesibulala-zinambuzane kwintsimi yezolimo.
-Ingasetyenziselwa ukudibanisa ezinye iikhompawundi eziphilayo, ezifana ne-synthetic intermediates kumachiza kunye ne-pesticides.
Indlela yokulungiselela:
-okanye inokwenziwa yi-nitro reaction. Indlela eqhelekileyo yokwenziwa yindlela yokusabela kwe-5-chloro-2-aminopyridine kunye ne-nitrite, ilandelwa yi-fluorination nge-reagent fluorinating.
Ulwazi ngoKhuseleko:
-yi-organic compound kwaye kufuneka isetyenziswe ngokuhambelana neenkqubo ezifanelekileyo zokhuseleko.
-Inokuba yingozi kwindalo, kwaye amanyathelo okukhusela kufuneka athathwe ukunciphisa impembelelo yawo kwindalo.
-Nxiba iiglavu zokukhusela, iiglasi zokhuseleko kunye nempahla yokukhusela xa usebenzisa okanye uphethe le khompawundi.
-Kufuneka igcinwe kwindawo eyomileyo, epholileyo, kwaye kude nezinto ezinokutsha kunye ne-oxidants.
-Ngaphambi kokusetyenziswa, kufuneka uqonde idatha yokhuseleko malunga nekhompawundi ngokweenkcukacha kwaye ulandele ukuphatha kwayo okuchanekileyo kunye neendlela zokulahla.
