Gabatarwa
2,5-Difluorobenzonitrile wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga wasu kaddarorin, amfani, hanyoyin shiri da bayanan aminci na 2,5-difluorobenzonitrile:
inganci:
-2,5-Difluorobenzonitrile mara launi zuwa kodadde rawaya crystal tare da ƙamshi mai ƙamshi.
- 2,5-difluorobenzonitrile kusan ba zai iya narkewa a cikin ruwa a cikin zafin jiki, amma mai narkewa a cikin kaushi na halitta kamar ethanol, acetone, da sauransu.
- wani fili ne mai kamshi mai kamshi.
Amfani:
- 2,5-Difluorobenzonitrile ana amfani dashi ko'ina a cikin ƙwayoyin halitta azaman reagent sinadarai don shirye-shiryen sauran mahadi.
- An yi amfani da shi sosai a cikin halayen fluorine da halayen aromatization saboda gabatarwar atom na fluorine na iya canza kaddarorin mahadi, haɓaka hydrophobicity da kwanciyar hankali na sinadarai.
Hanya:
- 2,5-difluorobenzonitrile za a iya shirya ta hanyar maye gurbin aromatic. Hanyar shiri na yau da kullun ita ce amsa para-dinitrobenzene tare da nitrosamines waɗanda ke haɓaka ta cuprous chloride da hydrofluoric acid don samun 2,5-difluorobenzonitrile.
Bayanin Tsaro:
- Lokacin sarrafa 2,5-difluorobenzonitrile, sanya kayan kariya masu dacewa kamar safofin hannu na kariya, tabarau, da rigar lab.
- Abu ne mai ban haushi wanda zai iya haifar da haushi ga idanu, fata, da kuma numfashi.
- Ya kamata a guji shakar tururi ko kura, fata da ido yayin da ake sarrafa su.
- Ya kamata a mai da hankali kan matakan rigakafin gobara da fashewa yayin ajiya da amfani, da nisantar tushen wuta da oxidants.
