2-Chloro-3-bromo-5-nitropyridine （CAS # 5470-17-7)

Intangiriro

Nibintu kama kama ifumbire mvaruganda ni C5H2BrClN2O2.

Kamere:

1. Kugaragara: Ni ifu ikomeye, mubisanzwe ifu ya kristaline.

2. Gukemura: Irashobora gushonga mumashanyarazi (nka dichloromethane, ether, nibindi), ariko gukomera mumazi ni bike.

Koresha:

Nibintu byingenzi bigizwe hagati, bikoreshwa cyane mubijyanye na synthesis.

1. Guhindura ibiyobyabwenge: Irashobora gukoreshwa muguhuza ibinyabuzima bikora, nkibiyobyabwenge, imiti yica udukoko, nibindi.

2. Guhindura irangi: Irashobora gukoreshwa muguhuza amarangi hamwe nibara.

3. Synthesis ya pesticide: irashobora gukoreshwa mumiti yica udukoko hamwe nudukoko.

Uburyo bwo Gutegura: Gutegura kwa

Birashobora gukorwa na aromatic nitration reaction, intambwe zihariye nizi zikurikira:

1. Mugihe gikwiye, pyridine ikoreshwa na acide nitricike yibanze kugirango ibone aside pyridine-3-nitric.

2. Acide Pyridine-3-nitricike noneho ikorwa hamwe na cuprous bromide kugirango ibone 3-bromopyridine.

3. Hanyuma, 3-bromopyridine isubizwa hamwe na chloride ya silver kugirango ibone ibicuruzwa byanyuma.

Amakuru yumutekano:

1. Ifite urwego runaka rwo kurakara nuburozi, nyamuneka wirinde guhura nuruhu, amaso na sisitemu yubuhumekero.

2. Mubikorwa, bigomba kwambara gants zo gukingira, indorerwamo za masike hamwe nibindi bikoresho byo kurinda umuntu.

3. Mugihe cyo kubika no gukoresha, bigomba kubikwa bitandukanye nibitwikwa, okiside nibindi bintu.

4. Mugihe cyo guta imyanda, nyamuneka wubahirize amabwiriza yo guta imyanda kugirango ugabanye ingaruka z’umwanda.
