Okwu mmalite
3-Nitropyridine (3-Nitropyridine) bụ ngwakọta organic nke nwere usoro kemịkalụ C5H4N2O2. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke 3-Nitropyridine:
Ọdịdị:
-ọdịdị: 3-Nitropyridine bụ kristal edo edo na-acha ọcha ma ọ bụ ntụ ntụ.
- Ebe mgbaze: ihe dịka 71-73 ° C.
- Ebe esi mmiri: Ihe dịka 285-287 ℃.
-Njupụta: ihe dịka 1.35g/cm³.
-Solubility: obere solubility na mmiri, soluble na organic solvents dị ka ethanol, acetone, wdg.
Jiri:
- 3-Nitropyridine nwere ike iji dị ka ihe na-emepụta ihe dị n'etiti maka njikọ nke ogige dị iche iche nke organic.
-Enwekwara ike iji ya dị ka ihe na-acha fluorescent na fotosentizer.
-N'ọrụ ugbo, enwere ike iji ya dị ka ihe eji eme ihe maka pesticides na fungicides.
Usoro:
-A na-enweta usoro nkwadebe bụ isi site na nitration nke 3-picolinic acid. Nke mbụ, 3-picolinic acid na-emeghachi omume na nitric acid na nitrated n'okpuru ọnọdụ mmeghachi omume kwesịrị ekwesị iji mepụta 3-Nitropyridine.
-A chọrọ ụfọdụ usoro nchekwa n'oge usoro nkwadebe, gụnyere izere kọntaktị na akpụkpọ anụ na anya, na-ezere isi ọkụ na ezigbo ikuku.
Ozi nchekwa:
- 3-Nitropyridine bụ ngwakọta organic. Ekwesịrị ịkpachara anya maka nchekwa nchekwa ndị a n'oge eji na nchekwa:
-ewe iwe na akpụkpọ na anya, zere kọntaktị mgbe ị na-eji. N'ihe gbasara kọntaktị, kpochaa ya ozugbo na nnukwu mmiri.
-Enwere ike imerụ akụkụ iku ume na sistem digestive, yabụ zere iku ume na oriri mgbe ị na-arụ ọrụ.
-N'oge nchekwa na ojiji, ọ dị mkpa ka ọ dị ala, kpọrọ nkụ ma mechie ya.
-Mkpofu mkpofu kwesịrị ịgbaso ụkpụrụ iwu obodo ma ghara ịkwanye ya ozugbo na isi mmiri ma ọ bụ gburugburu ebe obibi.
Biko mara na ozi a na-enye mmeghe n'ozuzu, yana usoro ụlọ nyocha akọwapụtara na nkọwa nchekwa dị mkpa ka a gbasoro usoro nchekwa ụlọ nyocha kemịkalụ dabara adaba. Maka mkpa nnwale pụrụ iche na iji ọnọdụ, biko kpọtụrụ ụlọ nyocha kemịkalụ pụrụ iche ma ọ bụ ọkachamara n'ọhịa.
