Okwu mmalite
2,3,5-Tribromopyridine bụ ihe mejupụtara ya na usoro kemịkalụ C5H2Br3N. Ihe a bụ mmalite nke ụfọdụ njirimara ya, ojiji ya, nhazi ya na ozi nchekwa:
Ọdịdị:
-ọdịdị: 2,3,5-Tribromopyridine bụ enweghị agba na-acha odo odo siri ike.
-Solubility: Ọ siri ike soluble na mmiri, mana enwere ike ịgbaze ya na ihe mgbaze organic dị ka chloroform, dichloromethane, wdg.
- Ebe mgbaze: 2,3,5-Tribomopyridine nwere ebe mgbaze nke ihe dịka 112-114 ° C.
Jiri:
- 2,3,5-Tribromopyridine na-ejikarị eme ihe dị ka reagent na etiti na njikọ organic.
-A na-eji ya n'ọtụtụ ebe n'ọhịa nke njikọ ọgwụ, imepụta pesticide na nkwadebe ihe ịcha mmiri.
-Na mgbakwunye, a pụkwara iji ya mee ihe dị ka ihe mmalite maka njikọ nke ogige organic metal (gụnyere polymers nhazi na ihe fotoelectric).
Ụzọ nkwadebe:
Enwere ike nweta usoro nkwadebe nke 2,3,5-Tribomopyridine site na usoro ndị a:
Nke mbụ, pyridine na-agbaze na ihe mgbaze organic dị ka dichloromethane ma ọ bụ chloroform.
2. Tinye bromine na ngwọta ma kpoo mmeghachi omume ahụ.
3. Mgbe emechara mmeghachi omume ahụ, a na-agbanye ngwaahịa brominated site na ntinye mmiri nke mmiri.
4. N'ikpeazụ, ngwaahịa ahụ dịpụrụ adịpụ ma dị ọcha site na nzacha, crystallization, wdg.
Ozi nchekwa:
- 2,3,5-Tribomopyridine agaghị ebute nsogbu nchekwa n'okpuru ọnọdụ ọrụ nkịtị.
-Ọ nwere ike ịkpasu iwe na akpụkpọ ahụ, anya na traktị iku ume, yabụ na-eyi ihe nchebe onwe onye kwesịrị ekwesị mgbe ị na-eji ya.
-Leba anya na usoro ụlọ nyocha kwesịrị ekwesị yana usoro nchekwa mgbe ị na-eji ngwa a.
-Mgbe ị na-echekwa ma na-edozi ogige ahụ, ekwesịrị ịkpachara anya iji zere kọntaktị na oxidants, acid siri ike, ntọala siri ike na ihe ndị ọzọ.
Biko mara na ozi dị n'elu bụ naanị maka ntụnye aka. Mgbe ị na-eji 2,3,5-Tribromopyridine ma ọ bụ ihe ọ bụla ọzọ kemịkalụ, biko soro na-atụ aro maka nchekwa ọrụ na ziri ezi ojiji, na-agụ na soro na nchekwa data mpempe akwụkwọ nke kemịkalụ dị mkpa.
