Intshayelelo
I-methyl-2-bromoisonicotinate yi-organic compound kunye ne-chemical formula C8H6BrNO2. Lulwelo olungenambala ukuya kumthubi, oluguquguqukayo kubushushu begumbi. I-hygroscopic kwaye i-soluble kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-dichloromethane.
I-methyl-2-bromoisonicotinate isetyenziswa ikakhulu njenge-catalysts kunye ne-intermediates kwi-organic synthesis reactions. Ingasetyenziswa njengento ebalulekileyo ekrwada kwiinkalo zamachiza, izibulala-zinambuzane kunye nedayi.
Indlela yokulungiselela i-methyl-2-bromoisonicotinate ifumaneka ngokubanzi ngokuphendula i-2-bromopyridine nge-methyl formate. Iimeko ezithile zovavanyo zinokwahluka, kodwa ngokubanzi, ukusabela kuqhutyelwa phantsi kweemeko ze-alkaline, kwaye iziseko ezisetyenziswa ngokuqhelekileyo ziyi-sodium hydroxide okanye i-sodium carbonate.
Ngolwazi lokhuseleko lwe-methyl-2-bromoisonicotinate, yinto ecasulayo kunye ne-corrosive compound. Ukuqhagamshelana nolusu, amehlo, okanye indlela yokuphefumula kunokubangela ukucaphuka kunye nokungahambi kakuhle. Ngoko ke, amanyathelo okhuseleko ayimfuneko kufuneka athathwe ngexesha lokusebenza, njengokugqoka iiglavu zokukhusela, iiglasi kunye nemaski. Ukongezelela, kufuneka igcinwe kwisitya esivaliweyo, kude nemithombo yomlilo kunye neendawo zokushisa eziphezulu. Ukuba kwenzeka ingozi, ngokukhawuleza uhlambulule indawo echaphazelekayo ngamanzi amaninzi kwaye ufune uncedo lwezonyango ngexesha elifanelekileyo. Landela iinkqubo ezifanelekileyo zokhuseleko kunye neengcebiso.
