Intshayelelo
Yikhompawundi ye-organic kunye ne-chemical formula C7H6FIS. Inkangeleko yayo ilulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elihlala ixesha elide nelikhethekileyo.
Le khompawundi isoloko isetyenziswa njengendawo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukulungisa ezinye izinto eziphilayo, ezifana nezibulala-zinambuzane, iziyobisi kunye nedayi. Isenokusetyenziswa njenge-agent eyinkimbinkimbi, i-solvent kunye ne-surfactant.
Indlela yokulungiselela i-halogen inokufumaneka ngamanyathelo alandelayo: Okokuqala, i-2-methylbenzoic acid iphendulwa kunye ne-oxidizing agent thionyl chloride ukuvelisa i-2-methylbenzoic acid chloride. I-asidi chloride iphinda iphendule nge-barium iodide ukunika i-2-iodo-5-methylbenzoic acid. Ekugqibeleni, i-2-iodo-5-methylbenzoic acid yaguqulwa yaba yi-phosphonium ngokusabela nge-fluoride yesilivere.
Xa usebenzisa, qaphela ukhuseleko lwayo. Lulwelo olunokutsha kwaye kufuneka lugcinwe kwaye lusetyenziswe ukunqanda umlilo kunye nobushushu obuphezulu. Inomphumela ovuselelayo kwesikhumba kunye namehlo, ugweme ukudibanisa ngqo. Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu kunye neglavu ngexesha lokusebenza. Njengeminye imichiza, ifanele isetyenziswe kwindawo engena umoya kwaye ilandele iinkqubo ezifanelekileyo zelabhoratri. Kwimeko yokuphefumla, ukungeniswa, okanye ukudibana kwesikhumba, funa uncedo lwezonyango ngokukhawuleza.
