Hoʻolauna
He mea hoʻohuihui olaola me ke ʻano kemika C8H9NO3. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Ke ʻano: He kala ʻole ia i ka paʻa kristal melemele māmā.
-Solubility: Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, akā ʻoi aku ka maikaʻi o ka solubility i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethylformamide.
-Ka helu heheʻe: ʻO ka helu heheʻe ma kahi o 72-75 degere Celsius.
E hoʻohana:
-Ke kimeka synthesis: He mea hoʻohana maʻamau ia e hiki ke hoʻohana ʻia e synthesize i nā mea hoʻohui organik ʻē aʻe.
-Nā noiʻi: Hiki ke hoʻohana ʻia no ka hoʻololi ʻana i ka synthesis organik a me nā noiʻi ʻē aʻe.
Kaʻina hoʻomākaukau:
Hiki ke hana ʻia ka Synthesis ma o nā pae aʻe:
1. ʻO ka mua, loaʻa ka 2-methyloxy-5-nitropyridine ma ka hana ʻana i ka 2-methyloxy-5-nitropyridine me ka waikawa nitric.
2. A laila e hoʻopili i ka 2-methoxy-5-nitropyridine me kahi methylating reagent (e like me ka methyl sodium iodide) e loaʻa ai ka huahana hope.
ʻIke palekana:
Ua kaupalena ʻia ka ʻikepili palekana, akā hiki ke make i ke kanaka a me ke kaiapuni. I ka wā e hoʻohana ai, pono e hahai i ka hana hoʻokolohua kūpono, a e lawe i nā hana pale pilikino e pono ai, e like me ke komo ʻana i nā aniani pale a me nā mīkina lima. Eia kekahi, pono e mālama ʻia ka mea hoʻohui a hoʻokuʻu pono ʻia i mea e pale ai i ka haumia o ke kaiapuni.
