Intshayelelo
Yikhompawundi ephilayo ene-chemical formula ye-C6H5ClFN. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Indalo:
-Imbonakalo: Lulwelo olungenambala ukuya kolutyheli olukhanyayo.
-Indawo yokubila: malunga ne-126-127°C.
-Ubuninzi: malunga ne-1.36g/cm³.
-I-Solubility: I-Soluble kwi-solvents ezininzi zezinto eziphilayo, ezifana ne-ethanol, i-ether kunye ne-dimethylformamide.
Sebenzisa:
-isetyenziswa ngokubanzi njengendawo ephakathi kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa ezinye izinto eziphilayo.
-Inokuthi isetyenziswe njengesixhobo sokuqala kwi-chiza synthesis, i-pesticide synthesis kunye ne-dayi synthesis.
Indlela yokulungiselela:
-okanye inokulungiswa yi-halogenation reaction ye-pyridine. Okokuqala, i-pyridine kunye ne-acetic acid ifumana i-chlorination reaction ukuvelisa i-2-chloropyridine. I-2-chloropyridine ke iguqulwa ibe yi-2-chloro-3-fluoropyridine ngokuphendula kwe-fluorination. Ekugqibeleni, i-2-chloro-3-fluoropyridine yayiyi-methylated isebenzisa i-methylation reaction.
Ulwazi ngoKhuseleko:
-Iikhompawundi ezicaphukisayo ezinokucaphukisa amehlo kunye nolusu.
-Ngexesha lokusetyenziswa kunye nokuphatha, amanyathelo afanelekileyo okhuseleko kufuneka athathwe, kubandakanywa ukugqoka iiglasi zokukhusela kunye neiglavu.
-Kuphephe ukuphefumla umphunga wekhompawundi kwaye uqinisekise ukuba usebenza kwindawo enomoya olungileyo.
-Xa ugcina kwaye uphatha, gcina kude nomlilo kunye ne-oxidizing agents ukuphepha ingozi yomlilo kunye nokudubula.
-Ngexesha lokusetyenziswa, ingqwalasela kufuneka ihlawulwe ukuthobela iinkqubo ezifanelekileyo zokusebenza kunye nemimiselo yokhuseleko.
