Intangiriro
Nibintu kama hamwe na formula ya chimique C7H3BrFN. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
-Ibigaragara: Kristaline idafite ibara.
-Gushonga ingingo: hafi 59-61 ° C.
-Ibintu bitetse: hafi 132-133 ℃.
-Ibipimo byinjira: Nta makuru yizewe.
-Gukemuka: Gushonga mumashanyarazi nka ether, dimethylformamide na benzene, idashonga mumazi.
Koresha:
-ni synthèse organique intera interineti ishobora gukoreshwa muguhuza ibice nkibiyobyabwenge, imiti yica udukoko n amarangi.
-Bishobora gukoreshwa nka reagent yo kwinjiza halogene mubintu bya aromatique muri synthesis.
Uburyo bwo Gutegura:
-fluorobenzonitrile irashobora gutegurwa wongeyeho igikombe cya bromide (CuBr) kuri 4-fluorobenzonitrile (C7H4FN).
Amakuru yumutekano:
-Bishobora kuba bitera uburakari kandi bikabora, kandi guhura nuruhu n'amaso bishobora gutera uburakari.
-Wambare ibikoresho bikwiye byo kurinda nka gogles, gants, na kote ya laboratoire mugihe ukora.
-Iyo ukoresheje no kubika, birakenewe kubahiriza inzira zogukora neza no kubika neza mubikoresho bifunze, kure yumuriro na okiside.
-Niba ushizemo umwuka cyangwa winjiye, shaka ubuvuzi bwihuse. Niba guhura bibaye, hita usukamo amazi yibasiwe n'amazi menshi hanyuma ushakire ubuvuzi.
