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

I-3-Bromo-2-chloro-6-methyl-5-nitropyridine i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

Umgangatho:
- Ukubonakala: I-3-Bromo-2-chloro-6-methyl-5-nitropyridine ngumgubo oqinileyo omhlophe ukuya okhanyayo.
- Ukunyibilika: Inokunyibilika okulungileyo kwizinyibilikisi ze-organic ezifana ne-ethanol, i-dimethylformamide kunye ne-chloroform, kodwa inokunyibilika okuphantsi kwamanzi.

Sebenzisa:
- Amayeza okubulala izitshabalalisi: Isenokusetyenziswa njengemathiriyeli ekrwada okanye iziphakathi kwimichiza yokubulala izinambuzane ekulungiseleleni imichiza yokubulala izinambuzane kunye nemichiza yokungunda.

Indlela:
Ukulungiswa kwe-3-bromo-2-chloro-6-methyl-5-nitropyridine kunokwenziwa ngamanyathelo alandelayo:
I-2-methyl-3-nitropyridine ichithwa kwi-ethanol kwaye i-asidi ye-sulfuric eyongeziweyo yongezwa ukuze ibangele ukusabela.
Umxube wokusabela wapholiswa kwaye waphathwa nge-thionyl chloride kunye ne-magnesium bromide.
Umxube wokuphendula uhlanjululwe, kwaye ke imveliso ihlanjululwa ngokunyuka kwe-evaporation kunye ne-crystallization.
Ngokucwenga, ukomisa kunye ne-pulverization, imveliso yokugqibela ye-3-bromo-2-chloro-6-methyl-5-nitropyridine ifunyenwe.

Ulwazi ngoKhuseleko:
- I-3-Bromo-2-chloro-6-methyl-5-nitropyridine iqinile enokutsha kwaye igwema ukudibanisa nemithombo yokutshisa.
- Ukungena komoya okulungileyo kufuneka kuthathwe ngexesha lokuphatha kunye nezixhobo zokukhusela zomntu ezifana neeglavu zokukhusela kunye nezibuko kufuneka zisetyenziswe.
- Kuphephe ukuphefumla uthuli okanye ukudibana nolusu kunye namehlo, kwaye ugweme ukungeniswa ngengozi.
- Nceda ugcine ngokufanelekileyo, kude nomlilo kunye nezinto ezinokutsha, kwaye kude nabantwana nezilwanyana.
