Isingeniso
I-3-Nitropyridine(3-Nitropyridine) iyinhlanganisela ye-organic ene-chemical formula C5H4N2O2. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-3-Nitropyridine:
Imvelo:
-Ukubukeka: I-3-Nitropyridine iyikristalu emhlophe kuya kokuphuzi okuphuzi noma i-crystal powder.
-Indawo yokuncibilika: cishe ku-71-73°C.
-Indawo yokubilisa: Mayelana ne-285-287 ℃.
-Ukuminyana: mayelana ne-1.35g/cm³.
-Ukunyibilika: ukuncibilika okuphansi emanzini, kuncibilika kuzincibilikisi eziphilayo njenge-ethanol, i-acetone, njll.
Sebenzisa:
- I-3-Nitropyridine ingasetshenziswa njenge-organic synthesis medium for synthesis of various compounds eziphilayo.
-Ingasetshenziswa futhi njengodayi we-fluorescent kanye ne-photosensitizer.
-Kwezolimo, ingasetshenziswa njengezinto ezingavuthiwe zokubulala izinambuzane kanye nezibulala fungi.
Indlela:
-Indlela yokulungiselela eyinhloko itholakala nge-nitrate ye-3-picolinic acid. Okokuqala, i-3-picolinic acid isabela nge-nitric acid futhi i-nitrate ngaphansi kwezimo ezifanele zokusabela ukukhiqiza i-3-Nitropyridine.
-Izinyathelo ezithile zokuphepha ziyadingeka phakathi nenqubo yokulungiselela, okuhlanganisa ukugwema ukuthintana nesikhumba namehlo, ukugcina kude nemithombo yomlilo kanye nomoya omuhle.
Ulwazi Lokuphepha:
- I-3-Nitropyridine iyinhlanganisela yezinto eziphilayo. Lezi zinyathelo zokuphepha ezilandelayo kufanele zinakwe ngesikhathi sokusetshenziswa nokugcinwa:
-Ukucasula isikhumba namehlo, gwema ukuthintana uma usebenzisa. Uma kwenzeka ukuthintana, hlambulula ngokushesha ngamanzi amaningi.
-Kungase kube yingozi emgudwini wokuphefumula kanye nesistimu yokugaya ukudla, ngakho-ke gwema ukuhogela kanye nokudla ngesikhathi sokusebenza.
-Ngesikhathi ukugcinwa nokusetshenziswa, kudinga ukugcinwa kuphansi, komile futhi kuvalwe.
-Ukulahlwa kwemfucuza kufanele kulandele imithetho yendawo futhi akufanele kukhishelwe ngqo emthonjeni wamanzi noma endaweni ezungezile.
Sicela uqaphele ukuthi lolu lwazi lunikeza isingeniso esijwayelekile, futhi izinqubo ezithile zelabhorethri kanye nemininingwane yokuphepha kufanele ilandelwe ngokuhambisana nezinqubo zokuphepha zaselabhorethri yamakhemikhali ezifanele. Ngezidingo ezikhethekile zokuhlola kanye nezimo zokusebenzisa, sicela uthintane nelabhorethri yamakhemikhali ekhethekile noma uchwepheshe kulo mkhakha.
