5-fluoro-2-nitrobenzoic acid (5-fluoro-2-nitrobenzoic acid) wani fili ne na kwayoyin halitta tare da tsarin sinadarai C7H4FNO4. Mai zuwa shine bayanin yanayinsa, amfaninsa, shirye-shiryensa da bayanan aminci:
Hali:
-Bayyana: 5-fluoro-2-nitrobenzoic acid fari ne ko a kashe-fari crystalline foda.
- Matsakaicin narkewa: Kimanin 172 ° C.
-Solubility: Dan kadan mai narkewa a cikin ruwa, mai narkewa a cikin wasu kaushi na kwayoyin halitta irin su alcohols da esters.
Amfani:
-Haɗin sinadarai: 5-fluoro-2-nitrobenzoic acid shine tsaka-tsakin haɗin gwiwar kwayoyin halitta da aka saba amfani dashi, wanda za'a iya amfani dashi don haɗa sauran mahadi, kamar kwayoyi, magungunan kashe qwari da rini.
-Manufofin bincike na kimiyya: Saboda tsarinsa mai dauke da fluorine da kungiyoyin nitro, 5-fluoro-2-nitrobenzoic acid yana da sinadarai na musamman kuma ana iya amfani dashi don bincike da gwaje-gwajen dakin gwaje-gwaje.
Hanya:
Hanyar shiri na 5-fluoro-2-nitrobenzoic acid yawanci ana samun su ta hanyar fluorination dauki na 2-nitrobenzoic acid.
1. Na farko, 2-nitrobenzoic acid yana amsawa tare da wakili na fluorine (kamar hydrogen fluoride ko sodium fluoride).
2. Bayan amsawa, an samo samfurin 5-fluoro-2-nitrobenzoic acid.
Ya kamata a lura cewa a lokacin shirye-shiryen shirye-shiryen, dole ne a yi amfani da yanayin aiki na gwaji masu dacewa da matakan tsaro don tabbatar da amincin gwajin.
Bayanin Tsaro:
- 5-fluoro-2-nitrobenzoic acid ana ɗauka a matsayin wani wuri mai aminci a ƙarƙashin yanayi na gabaɗaya, amma har yanzu yana buƙatar kulawa da hankali kuma ya bi hanyoyin gwaji masu dacewa.
-Idan ana cudanya da wannan sinadari, a nisanci haduwar fata kai tsaye da shakar kurarta.
-A cikin tsarin amfani da ajiya, da fatan za a kare kayan aikin dakin gwaje-gwaje yadda ya kamata, kuma bi ƙa'idodin aminci masu dacewa.
-Idan wani hadari ya faru ko wanda ake zargin guba ne, a nemi kulawar likita nan da nan kuma a kawo takardar bayanan lafiyar fili.
