Hordhac
2-Bromo-5-nitropyridine waa unug dabiici ah oo leh qaacidada kiimikada C5H3BrN2O2. Kuwa soo socda waa sharaxaadda dabeecadeeda, isticmaalkeeda, diyaarinteeda iyo macluumaadka badbaadada:
Dabeecadda:
2-Bromo-5-nitropyridine waa adage cad oo leh dhadhan oxalic acid yar. Waxay leedahay kuleyl sare iyo xasilloonida kiimikada. Waxoogaa ku milmay biyaha heerkulka qolka, ku milmay dareerayaasha organic sida ethanol iyo acetone.
Isticmaal:
2-Bromo-5-nitropyridine waxay leedahay codsiyo badan oo kala duwan. Waa walxo ceeriin ah oo muhiim ah iyo dhexdhexaad ka ah isku-dhafka organic. Waxaa loo isticmaali karaa isku-darka sunta cayayaanka, dheeha, qalabka sawir-qaadista iyo xeryahooda daawada. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa sida kicinta iyo ligand.
Habka Diyaarinta:
Hababka 2-Bromo-5-nitropyridine synthesis inta badan waa kuwan soo socda:
1. by 2-bromopyridine iyo falcelinta nitric acid hoos xaaladaha acidic.
2. by 3-bromopyridine iyo falcelinta nitrite sodium hoos xaaladaha alkaline.
Macluumaadka Badbaadada:
2-Bromo-5-nitropyridine waa iskudhis sun ah oo leh khataro gaar ah. U fiirso taxaddarrada soo socda ee badbaadada inta lagu jiro isticmaalka iyo kaydinta:
1. Iska ilaali in la neefsado boodhka ama uumiga, waa in ay ahaataa meel hawo fiican leh oo lagu shaqeeyo.
2. ka fogow taabashada maqaarka, indhaha iyo xuubabka xuubka, sida taabashada waa in isla markiiba lagu luqluqiyaa biyo badan, oo raadso gargaar caafimaad.
3. fiiro gaar ah u yeelo tallaabooyinka ka hortagga dabka iyo qaraxa, iska ilaali taabashada walxaha guban kara.
4. Ku kaydi weel xiran, oo ka fog dabka iyo oksidant.
5. Tuur sida waafaqsan xeerarka deegaanka si looga fogaado in si toos ah deegaanka loogu sii daayo.
Soo koobid:
2-Bromo-5-nitropyridine waa unug dabiici ah oo leh codsiyo kala duwan. Si kastaba ha ahaatee, sababtoo ah sunta, waxaa lagama maarmaan ah in fiiro gaar ah loo yeesho hawlgalka badbaadada leh, kaydinta saxda ah iyo qashinka qashinka.
