Intshayelelo
I-organic compound kunye ne-chemical formula C7H7N2O3. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Indalo:
-Imbonakalo: Yikristale etyheli okanye umgubo.
-Ukunyibilika: Kuphantse kwanganyibiliki emanzini kwaye kulula ukunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-chloroform kunye ne-dimethyl sulfoxide.
-Indawo yokunyibilika: Indawo yayo yokunyibilika imalunga ne-135-137 degrees Celsius.
-Iimpawu zeChemical: Yinto equlethwe yinitrogen enevumba elimnandi enomsebenzi othile wekhemikhali.
Sebenzisa:
-Ingasetyenziselwa njengento ephakathi kwi-synthesis yezinye izinto eziphilayo.
-Ingasetyenziswa njengento ekrwada yokubulala izitshabalalisi kunye nemichiza kwintsimi yezolimo.
Indlela:
-inokulungiswa ngokuphendula i-2-methylpyridine nge-nitric acid. Amanyathelo athile alandelayo: ukuchithwa kwe-2-methylpyridine kwi-ethanol, ukongeza i-nitric acid egxininisiweyo, kunye nokufumana umkhiqizo nge-crystallization emva kokuphendula.
Ulwazi ngoKhuseleko:
-Kuyingozi kakhulu ekudibaneni nolusu, ukuphefumla okanye emva kokungena.
-Kuphephe ukudibana kwesikhumba kunye nokuphefumla xa udibana. Nxiba iglavu kunye neglavu ukuba kuyimfuneko.
-Qwalasela iinkqubo zokusebenza ezikhuselekileyo ngexesha lokuphatha nokugcina kwaye utywine ngokufanelekileyo.
-ukuba kuyimfuneko, bhekisa kwiPhepha leDatha loKhuseleko lweMichiza (MSDS) ngolwazi oluthe kratya lokhuseleko.
