Intangiriro
2,5-Dichloro-3-nitropyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro yumutungo wacyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
- Kugaragara: 2,5-Dichloro-3-nitropyridine ni ibara ritagira ibara ryijimye.
- Gukemura: Irashobora gushonga mumashanyarazi kama nka Ethanol, dimethyl ether na chloroform, ariko ntigashonga mumazi.
- Igihagararo: Ikomatanyirizo rihamye mubushyuhe bwicyumba, ariko riraturika mubushyuhe bwinshi cyangwa uhuye ningingo zikomeye za okiside.
Koresha:
- Imiti yica udukoko: Irashobora gukoreshwa nkumuti wica udukoko kandi igira ingaruka nziza zo kurwanya udukoko.
Uburyo:
Uburyo bwa synthesis ya 2,5-dichloro-3-nitropyridine mubisanzwe harimo nitrification reaction na chlorination reaction. Muri byo, uburyo bwa synthesis gakondo ni uguhindura nitrat 2,5-dichloropyridine hamwe na aside nitric imbere ya acide sulfurike. Ubundi buryo ni ugukora 2-nitro-5-chloropyridine hamwe na bromide ya acide acide kugirango ikore 2,5-dichloro-3-nitropyridine.
Amakuru yumutekano:
- 2,5-Dichloro-3-nitropyridine ni urugingo ngengabuzima rugomba gukemurwa neza kugirango rwirinde guhura nuruhu, amaso, hamwe nubuhumekero.
- Kwambara ibikoresho bikingira birinda, harimo inkweto zo kurinda amaso, gants, n'ingabo zo mu maso, mugihe ukora.
- Mugihe cyo gukora, irinde guhumeka imyuka, ibicu cyangwa imyuka kandi ukomeze guhumeka neza.
- Mugihe uhuye nuruhu cyangwa amaso, kwoza ako kanya n'amazi menshi hanyuma ubaze muganga.
- Iyo ubitse, 2,5-dichloro-3-nitropyridine igomba kubikwa ahantu humye, hakonje, hahumeka neza, kure yumuriro na okiside.
