Iseda:
2-Bromo-5-nitropyridine jẹ funfun ti o lagbara pẹlu itọwo oxalic acid diẹ. O ni igbona giga ati iduroṣinṣin kemikali. Tiotuka die-die ninu omi ni iwọn otutu yara, tiotuka ninu awọn olomi Organic gẹgẹbi ethanol ati acetone.
Lo:
2-Bromo-5-nitropyridine ni ọpọlọpọ awọn ohun elo. O jẹ ohun elo aise pataki ati agbedemeji ni iṣelọpọ Organic. O le ṣee lo ni iṣelọpọ ti awọn ipakokoropaeku, awọn awọ, awọn ohun elo ti o ṣe akiyesi ati awọn agbo ogun elegbogi. Ni afikun, o tun le ṣee lo bi ayase ati ligand.
Ọna Igbaradi:
Awọn ọna iṣelọpọ 2-Bromo-5-nitropyridine jẹ pataki awọn atẹle:
1. nipasẹ 2-bromopyridine ati iṣesi acid nitric labẹ awọn ipo ekikan.
2. nipasẹ 3-bromopyridine ati iṣuu soda nitrite lenu labẹ awọn ipo ipilẹ.
Alaye Abo:
2-Bromo-5-nitropyridine jẹ agbo ogun oloro pẹlu awọn ewu kan. San ifojusi si awọn iṣọra ailewu atẹle lakoko lilo ati ibi ipamọ:
1. yago fun inhalation ti eruku tabi oru, yẹ ki o wa ni kan daradara-ventilated ibi lati ṣiṣẹ.
2. yago fun olubasọrọ pẹlu awọ ara, oju ati awọn membran mucous, gẹgẹbi olubasọrọ yẹ ki o fi omi ṣan lẹsẹkẹsẹ pẹlu ọpọlọpọ omi, ki o si wa iranlọwọ iwosan.
3. san ifojusi si ina ati awọn idena idena bugbamu, yago fun olubasọrọ pẹlu awọn ohun elo flammable.
4. Fipamọ sinu apo ti a fi pa, kuro lati ina ati oxidant.
