Intshayelelo

I-3-Nitropyridine (3-Nitropyridine) i-organic compound kunye ne-chemical formula C5H4N2O2. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-3-Nitropyridine:

 

Indalo:

-Inkangeleko: I-3-Nitropyridine yikristale emhlophe ukuya kwi-yellow yellow okanye i-crystal powder.

-Indawo yokunyibilika: malunga ne-71-73°C.

-Indawo yokubilisa: Malunga ne-285-287 ℃.

-Ubuninzi: malunga ne-1.35g/cm³.

-I-Solubility: i-solubility ephantsi emanzini, i-soluble kwii-solvents eziphilayo ezifana ne-ethanol, i-acetone, njl.

 

Sebenzisa:

- I-3-Nitropyridine ingasetyenziselwa njenge-organic synthesis intermediate ye-synthesis yeentlobo ezahlukeneyo zezinto eziphilayo.

-Inokusetyenziswa kwakhona njengedayi ye-fluorescent kunye ne-photosensitizer.

-Kwezolimo, inokusetyenziswa njengento ekrwada kwizibulali zinambuzane kunye nemichiza yokungunda.

 

Indlela:

-Indlela ephambili yokulungiselela ifunyenwe nge-nitration ye-3-picolinic acid. Okokuqala, i-3-picolinic acid iphendulwa nge-nitric acid kunye ne-nitrate phantsi kweemeko ezifanelekileyo zokuphendula ukuvelisa i-3-Nitropyridine.

-Amanyathelo athile okhuseleko afunekayo ngexesha lenkqubo yokulungiselela, kubandakanywa nokuphepha ukudibanisa nesikhumba kunye namehlo, ukugcina kude nemithombo yomlilo kunye nomoya omhle.

 

Ulwazi ngoKhuseleko:

- I-3-Nitropyridine i-organic compound. La manyathelo okhuseleko alandelayo kufuneka athathelwe ingqalelo ngexesha lokusetyenziswa kunye nokugcinwa:

-Ukucaphukisa ulusu kunye namehlo, ugweme ukudibanisa xa usebenzisa. Kwimeko yoqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi.

-Inokuba yingozi kwindlela yokuphefumula kunye nenkqubo yokugaya, ngoko ugweme ukuphefumla kunye nokungena ngexesha lokusebenza.

-Ngexesha lokugcinwa kunye nokusetyenziswa, kufuneka igcinwe iphantsi, yomile kwaye ivalwe.

-Ukulahlwa kwenkunkuma kufuneka kulandele imimiselo yendawo kwaye akufuneki kulahlwe ngqo kumthombo wamanzi okanye kwindawo engqongileyo.

 

Nceda uqaphele ukuba le ngcaciso inika intshayelelo ngokubanzi, kwaye iinkqubo ezithile zelabhoratri kunye neenkcukacha zokhuseleko kufuneka zilandelwe ngokungqinelana neenkqubo ezifanelekileyo zokhuseleko lwebhubhoratri yeekhemikhali. Ngeemfuno ezizodwa zovavanyo kunye neemeko zokusebenzisa, nceda uqhagamshelane nelebhu yeekhemikhali ezikhethekileyo okanye ingcali kwintsimi.
