3-BROMO-2-CHLORO-5-NITRO-6-PICOLINE(CAS# 856834-95-2)

3-BROMO-2-CHLORO-5-NITRO-6-PICOLINE (CAS# 856834-95-2) isingeniso

I-3-Bromo-2-chloro-6-methyl-5-nitropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:
- Ukubukeka: I-3-Bromo-2-chloro-6-methyl-5-nitropyridine iyimpushana eqinile emhlophe kuya kokuphuzi.
- Ukunyibilika: Inokuncibilika okuhle kuzincibilikisi eziphilayo njenge-ethanol, i-dimethylformamide ne-chloroform, kodwa inokuncibilika okuphansi emanzini.

Sebenzisa:
- Izibulala-zinambuzane: Ingasetshenziswa futhi njengezinto ezingavuthiwe noma izithasiselo zezibulala-zinambuzane ekulungiseni izibulala-zinambuzane nezibulala-sikhunta.

Indlela:
Ukulungiswa kwe-3-bromo-2-chloro-6-methyl-5-nitropyridine kungenziwa ngezinyathelo ezilandelayo:
I-2-methyl-3-nitropyridine incibilika ku-ethanol futhi i-sulfuric acid eyeqile iyengezwa ukuze kubangele ukusabela.
Ingxube yokusabela yapholiswa futhi yaphathwa nge-thionyl chloride ne-magnesium bromide.
Ingxube yokusabela iyahlanjululwa, bese umkhiqizo uhlanzwa ngokuhwamuka kanye ne-crystallization.
Ngokucwenga, ukomisa kanye ne-pulverization, umkhiqizo wokugcina we-3-bromo-2-chloro-6-methyl-5-nitropyridine utholakala.

Ulwazi Lokuphepha:
- I-3-Bromo-2-chloro-6-methyl-5-nitropyridine iqinile evuthayo futhi igwema ukuthintana nemithombo yokuthungela.
- Ukungena komoya okuhle kufanele kuthathwe ngesikhathi sokuphatha kanye nezinto zokuzivikela ezifana namagilavu ​​okuzivikela kanye nezibuko kufanele kusetshenziswe.
- Gwema ukuhogela uthuli noma ukuthinta isikhumba namehlo, futhi ugweme ukungenwa ukudla ngephutha.
- Sicela ugcine kahle, kude nomlilo nezinto ezivuthayo, futhi kude nezingane nezilwane.
