Nhanganyaya
Iyo organic compound ine kemikari formula C8H9NO3. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: Iyo isina ruvara kune yero yekristaro yakasimba.
-Solubility: Inenge isingasviki mumvura, asi ine zviri nani kunyungudika mune organic solvents senge ethanol uye dimethylformamide.
-Kunyungudika: Nzvimbo yekunyunguduka inenge 72-75 degrees Celsius.
Shandisa:
-Chemical synthesis: Inowanzo shandiswa yepakati musanganiswa inogona kushandiswa kugadzira mamwe ma organic compounds.
-Research: Inogona kushandiswa kune organic synthesis maitiro uye kumwe kutsvagisa marabhoritari.
Kugadzirira nzira:
Synthesis inogona kuitwa kuburikidza nematanho anotevera:
1. Kutanga, 2-methyloxy-5-nitropyridine inowanikwa nekuita 2-methyloxy-5-nitropyridine ne nitric acid.
2. Zvadaro ita 2-methoxy-5-nitropyridine ne methylating reagent (yakadai semethyl sodium iodide) kuti uwane chigadzirwa chekupedzisira.
Zvekuchengetedza
Iyo data yekuchengetedza ishoma, asi inogona kuve ine muchetura kuvanhu nenharaunda. Paunenge uchishandisa, unofanirwa kutevedzera maitiro akakodzera murabhoritari, uye kutora matanho anodiwa ekuzvidzivirira, sekupfeka magirazi ekudzivirira nemagirovhosi. Pamusoro pezvo, mukomboni unofanirwa kuchengetwa uye kuraswa zvakanaka kudzivirira kusvibiswa kwenharaunda.
