Intangiriro
Ibyiza: Ifite imbaraga nke mumazi no gukemuka neza mumashanyarazi. Imiterere yimiti irakora kandi ikunda kugabanuka, alkylation nibindi bitekerezo.
Koresha:
2-hydroxy-3-nitro-5-chloropyridine ifite agaciro gakoreshwa muri synthesis. Irashobora gukoreshwa nkigihe cyingenzi hagati ya synthesis organique kandi igira uruhare mubikorwa byinshi bya synthesis synthesis, nka synthesis ya hop flavour compound.
Uburyo:
Hariho uburyo bwinshi bwo gutegura 2-hydroxy-3-nitro-5-chloropyridine, uburyo busanzwe bubonwa na nitrifisation ya 2-azacyclopentadiene, hanyuma hakabaho hydrogenation hamwe na chlorine reaction kugirango ubone ibicuruzwa bigenewe.
Amakuru yumutekano:
Irinde guhura na okiside ikomeye, acide ikomeye, alkalis ikomeye nibindi bintu kugirango wirinde ubukana.
Witondere ingamba zo gukingira mugihe ukoresha, kandi wambare ibikoresho bikingira umuntu, nka gants z'umutekano, indorerwamo, nibindi.
Mugihe ukoresha cyangwa ubitse, shyira 2-hydroxy-3-nitro-5-chloropyridine ahantu hakonje, hahumeka neza, kure yumuriro nubushyuhe bwinshi.
