nature:
2-Nitro-3-methoxypyridine yakasimba ine kuchena kusvika kuchiedza checrystalline kutaridzika. Iine hwema hwakasimba uye inopisa.
Kushandiswa: Inogona zvakare kushandiswa sechinhu chekugadzira chedhayi uye pigment.
Kugadzira nzira:
2-Nitro-3-methoxypyridine inogona kugadzirwa nekuita p-methoxyaniline ine nitric acid. Iyo chaiyo synthesis nzira inogona kuve nitration reaction yemethoxyaniline, inoteverwa nekuita kweyakawanikwa 2-nitro-3-methoxyaniline ine acetone, uye pakupedzisira dehydration reaction.
Chekuchengetedza ruzivo:
2-Nitro-3-methoxypyridine inogona kuva muchetura kumuviri wemunhu sezvo ichigona kukonzera kushatirwa kweganda, maziso, uye kufema system. Matanho akakodzera ekuchengetedza anofanirwa kutorwa panguva yekushandiswa uye kubata, sekupfeka magirovhosi ekudzivirira, magirovhosi, uye masks. Iva nechokwadi chekudzivirira kubata nezvinhu zvinopfuta uye usafemedze huruva, gasi, kana mhute. Kuchenjerera kunofanira kubhadharwa pakuchengetedza kure nezvinopisa moto uye nzvimbo dzekushisa kwepamusoro paunenge uchishandisa nekuchengetedza.
