4-BRMO-3 5-DICHLOROPYRIDINE(CAS# 343781-45-3)

Nhanganyaya

4-Bromo-3,5-dichloropyridine is organic compound ine kemikari formula C5H2BrCl2N. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:

Zvakasikwa:

4-Bromo-3,5-dichloropyridine ikristaro isina ruvara kana yakachenuruka ine kunhuhwirira kwakakosha. Kunyungudika kwayo kuri pakati pe80-82°C uye painofashaira iri pakati pe289-290°C. Hainyungudike mumvura pane tembiricha yakajairika, asi inonyungudika muorganic solvents senge ethanol uye chloroform.

Shandisa:

4-Bromo-3,5-dichloropyridine inoshandiswa zvakanyanya muindasitiri yemakemikari. Iyo yakakosha yepakati peiyo pyridine makomisheni uye inogona kushandiswa mukuumbwa kwemamwe ma organic compounds nemishonga. Iine kugadzikana kwakanaka kwemakemikari uye reactivity, uye inogona kushandiswa sechinhu chinokonzera, ligand, dhayi uye mishonga yekuuraya zvipembenene.

Kugadzirira nzira:

Nzira yekugadzirira ye 4-Bromo-3,5-dichloropyridine inowanzogadziriswa nekugadzirisa kushandiswa kwepyridine. Iyo inowanzoshandiswa nzira yekugadzirira inosanganisira maitiro e pyridine ne bromine uye ferric chloride, uye kushandiswa kwekutsiva kunoitwa pasi pemamiriro akakodzera kuti uwane chigadzirwa chinotarirwa. Iyo nzira yekugadzirira inoda kudzora tembiricha yekuita, pH kukosha uye nguva yekuita uye mamwe ma paramita kuti uwane yakakwirira kuchena zvigadzirwa.

Zvekuchengetedza

4-Bromo-3,5-dichloropyridine inhengo yakagadzikana uye yakachengeteka pasi pemamiriro ezvinhu, asi zvichiri kudiwa kubhadhara kushanda kwakachengeteka. Inogona kupinda mumuviri kuburikidza nekufema, kubata ganda uye kupinza. Kufemera pamusoro pemagasi neguruva kunogona kukonzera kushatirwa, zvichikonzera kufema uye kusagadzikana kweziso. Kubata neganda kunogona kukonzera kutsvuka, kurira uye kusawirirana. Kudya kwekomboni kunogona kukonzera kusagadzikana kwemudumbu uye chepfu mhedzisiro. Naizvozvo, midziyo yekudzivirira yakakodzera inofanirwa kupfekwa panguva yekushandiswa kudzivirira kubata kwakananga uye kufema. Muchiitiko chetsaona, kurapwa kwekukurumidzira kunofanirwa kuitwa nenguva uye nyanzvi dzinofanira kubvunzwa. Mukuwedzera, inofanira kuchengetwa munzvimbo yakaoma, ine mhepo, kure nemoto uye oxidizing agents.
