Intangiriro
4-Bromo-3,5-dichloropyridine ni ifumbire mvaruganda hamwe na formula ya chimique C5H2BrCl2N. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
4-Bromo-3,5-dichloropyridine ni kirisiti itagira ibara cyangwa yera yumuhondo ifite impumuro idasanzwe. Ahantu ho gushonga ni hagati ya 80-82 ° C naho aho itetse iri hagati ya 289-290 ° C. Ntishobora gushonga mumazi mubushyuhe busanzwe, ariko irashonga mumashanyarazi nka Ethanol na chloroform.
Koresha:
4-Bromo-3,5-dichloropyridine ikoreshwa cyane mu nganda zikora imiti. Nibintu byingenzi byingirakamaro hagati ya pyridine kandi birashobora gukoreshwa muguhuza ibindi bintu kama nibiyobyabwenge. Ifite imiti ihamye kandi ikora neza, kandi irashobora gukoreshwa nka catalizator, ligand, irangi hamwe nudukoko twangiza udukoko.
Uburyo bwo Gutegura:
Uburyo bwo gutegura 4-Bromo-3,5-dichloropyridine muri rusange bigerwaho nigisubizo cyo gusimbuza pyridine. Uburyo bukoreshwa muburyo bwo gutegura burimo reaction ya pyridine hamwe na bromine na ferric chloride, kandi reaction yo gusimburwa ikorwa mugihe gikwiye kugirango ubone ibicuruzwa bigenewe. Igikorwa cyo kwitegura gikeneye kugenzura ubushyuhe bwa reaction, pH agaciro nigihe cyo kubyitwaramo nibindi bipimo kugirango ubone ibicuruzwa byera cyane.
Amakuru yumutekano:
4-Bromo-3,5-dichloropyridine nikintu gihamye kandi gifite umutekano mubihe rusange, ariko biracyakenewe kwitondera imikorere itekanye. Irashobora kwinjira mu mubiri binyuze mu guhumeka, guhuza uruhu no kuribwa. Guhumeka imyuka myinshi hamwe n ivumbi birashobora gutera uburakari, bigatera guhumeka no kutabona neza. Guhura nuruhu birashobora gutera umutuku, gutitira na allergique. Kwinjiza ibimera bishobora gutera gastrointestinal kutagira ingaruka ningaruka zuburozi. Kubwibyo, ibikoresho birinda umutekano bigomba kwambarwa mugihe cyo gukoresha kugirango wirinde guhura no guhumeka neza. Mugihe habaye impanuka, ubuvuzi bwihutirwa bugomba gukorwa mugihe kandi abahanga bagomba kubazwa. Byongeye kandi, igomba kubikwa ahantu humye, ihumeka, kure yumuriro na okiside.
