-Gushonga Ingingo: 44-46 ° C.
-Ibintu bitetse: 262 ° C.
-Gukemuka muri: inzoga na ether, zidashonga mumazi
Koresha:
ni ingirakamaro hagati, ikoreshwa cyane murwego rwa synthesis. Irashobora gukoreshwa mugushushanya ibintu bitandukanye bikoresha ibinyabuzima, nkibiyobyabwenge, amarangi nudukoko.
Uburyo bwo Gutegura:
Synthesis irashobora gukorwa binyuze mu ntambwe zikurikira:
1. 2-Nitro-6-formylpyridine yabonetse mugukora 2-nitro-6-nitro-pyridine hamwe na acide sulfurike.
2. Hakozwe reaction ya 2-nitro-6-formylpyridine na chloromethyl ether munsi ya alkali.
3. Intambwe yo kweza no gutegera byakozwe kugirango ubone ibicuruzwa byiza.
Amakuru yumutekano:
Ibintu bishobora guteza akaga bishobora gutera uburakari hamwe na allergie reaction muguhura cyangwa guhumeka. Mugihe ukora, ambara ingamba zikwiye zo gukingira nka gants, ibirahure n imyenda ikingira, kandi urebe ko icyo gikorwa gikorerwa ahantu hafite umwuka mwiza. Mugihe cyo kubika no gutunganya, ugomba kwirinda guhura na okiside ikomeye nibikoresho byaka umuriro.
