Nhanganyaya

Iyo organic compound ine kemikari formula ndeye C5H2BrClN2O2.

 

Zvakasikwa:

1. Chitarisiko: Iyo yakasimba, kazhinji yero crystalline powder.

2. Solubility: Inogona kunyungudutswa mune organic solvents (yakadai se dichloromethane, ether, etc.), asi kunyungudika mumvura kwakaderera.

 

Shandisa:

Icho chinhu chakakosha chepakati chepakati, chinoshandiswa zvakanyanya mumunda wemakemikari synthesis.

1. Mushonga wemishonga: Inogona kushandiswa kugadzira biologically active compounds, semishonga, mishonga yezvipembenene, nezvimwe.

2. Dye synthesis: Inogona kushandiswa kugadzira dhayi uye pigments.

3. kugadzirwa kwemishonga yezvipembenene: inogona kushandiswa kugadzira mishonga yezvipembenene nesora.

 

Kugadzirira Nzira: Kugadzirira kwe

inogona kuitwa nekunhuhwirira nitration reaction, iwo matanho chaiwo ndeaya anotevera:

1. Pasi pemamiriro akakodzera, pyridine inobatwa ne concentrated nitric acid kuti iwane pyridine-3-nitric acid.

2. Pyridine-3-nitric acid inobva yaitwa ne cuprous bromide kuti iwane 3-bromopyridine.

3. Pakupedzisira, 3-bromopyridine inobatwa nesirivha chloride kuti iwane chigadzirwa chekupedzisira.

 

Zvekuchengetedza

1. ine imwe chiyero chekushatirwa uye chepfu, ndapota dzivisa kusangana neganda, maziso uye kufema system.

2. mukushanda, inofanira kupfeka magirovhosi ekudzivirira, magirazi uye masiki uye zvimwe zvekuzvidzivirira nazvo.

3. panguva yekuchengetedza uye kushandiswa, inofanira kuchengetwa zvakasiyana kubva kune zvinopisa, oxidants nezvimwe zvinhu.

4. Paunenge uchirasa tsvina, tapota teerera mitemo yemunharaunda yekurasa tsvina kuderedza dambudziko rekusvibiswa kwezvakatipoteredza.
