Intangiriro
2,3,5-Tribromopyridine ni ifumbire mvaruganda hamwe na formula ya chimique C5H2Br3N. Ibikurikira ni intangiriro kuri bimwe mubiranga, ikoreshwa, formulaire namakuru yumutekano:
Kamere:
-Ibigaragara: 2,3,5-Tribromopyridine ni ibara ritagira ibara ryijimye.
-Gukemuka: Ntibishobora gushonga mumazi, ariko birashobora gushonga mumashanyarazi nka chloroform, dichloromethane, nibindi.
-Gushonga: 2,3,5-Tribromopyridine ifite aho ishonga igera kuri 112-114 ° C.
Koresha:
- 2,3,5-Tribromopyridine ikoreshwa kenshi nka reagent kandi hagati muri synthesis.
-Bikoreshwa cyane mubijyanye no guhuza ibiyobyabwenge, gukora imiti yica udukoko no gutegura amarangi.
-Muyongeyeho, irashobora kandi gukoreshwa nkibikoresho byo gutangira guhuza ibyuma kama kama (harimo guhuza polymers nibikoresho byamafoto).
Uburyo bwo Gutegura:
Uburyo bwo gutegura 2,3,5-Tribromopyridine burashobora kugerwaho nintambwe zikurikira:
Ubwa mbere, pyridine ishonga mumashanyarazi nka dichloromethane cyangwa chloroform.
2. Ongeramo bromine kubisubizo hanyuma ushushe reaction.
3. Nyuma yo kurangiza reaction, ibicuruzwa bivangwa na hydrolyz byongewemo amazi.
4. Hanyuma, ibicuruzwa byitaruye kandi bisukurwa no kuyungurura, korohereza ibintu, nibindi.
Amakuru yumutekano:
- 2,3,5-Tribromopyridine ntabwo izatera ibibazo byumutekano mugihe gisanzwe gikora.
-Bishobora gutera uburakari kuruhu, amaso hamwe nu myanya y'ubuhumekero, bityo rero wambare ibikoresho bikingira umuntu igihe ubikoresheje.
-Kurikiza uburyo bukwiye bwa laboratoire n'ingamba z'umutekano mugihe ukemura iki kigo.
-Iyo kubika no gutunganya uruganda, hagomba kwitonderwa kugirango wirinde guhura na okiside, acide ikomeye, ishingiro rikomeye nibindi bintu.
Nyamuneka menya ko amakuru yavuzwe haruguru ari ayerekeranye gusa. Mugihe ukoresheje 2,3,5-Tribromopyridine cyangwa ikindi kintu cyose cyimiti, nyamuneka ukurikize ibyifuzo byogukora neza no gukoresha neza, hanyuma usome kandi ukurikize urupapuro rwumutekano rwimiti ijyanye.
