Intshayelelo
Yikhompawundi ephilayo. Ine-formula yekhemikhali ye-C5H3BrN4O2 kunye ne-molecular weight ye-213.01g / mol. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Indalo:
-Imbonakalo: Yikristale etyheli ukuya kwiorenji okanye umgubo;
-Indawo yokunyibilika: malunga ne-117-120 degrees Celsius;
-Ukunyibilika: Inyibilika kancinane emanzini kwaye inyibilika kwezinye izinyibilikisi zendalo ezifana neealkoholi, iiesters kunye neeketones.
Sebenzisa:
-I-Drug synthesis: Idla ngokusetyenziswa njengendawo ephakathi kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa iziyobisi ezahlukeneyo, idayi, i-pesticides kunye nezinye iikhompawundi.
Indlela yokulungiselela:
Zininzi iindlela zokulungiselela, kwaye le ilandelayo yenye yazo:
1. Okokuqala, i-3-bromo-5-nitropyridine iphendulwa kunye ne-ammonia ukufumana i-3-nitro-5-aminopyridine.
2. Isiphumo se-3-nitro-5-aminopyridine emva koko sisabela nge-bromoalkane okanye i-acetyl ukufumana imveliso yokugqibela.
Ulwazi ngoKhuseleko:
Ngokuqhelekileyo ikhuselekile xa isetyenziswe kwaye igcinwe ngokuchanekileyo. Nangona kunjalo, oku kulandelayo kufuneka kuthathwe:
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi kunye needyasi zaselebhu;
-Kuphephe ukudibana nolusu, umlomo kunye namehlo. Ukuba kukho uqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi;
-Sebenzisa kunye nokugcina i-compound kwindawo enomoya kakuhle ukuphepha ukuphefumla igesi okanye uthuli;
-Musa ukugcina okanye ukusebenzisa i-compound enezinto ezivuthayo;
-Funda ngononophelo kwaye ulandele ukhuseleko olufanelekileyo kunye nemigaqo yokulahlwa kwenkunkuma phambi kokusetyenziswa okanye ukulahlwa.
Nceda uqaphele ukuba ulwazi olunikeziweyo ngasentla lwenzelwe ireferensi kuphela, kwaye imeko ethile kufuneka iqondwe ngakumbi kwaye iqinisekiswe ngokweemfuno zokwenene.
