Nhanganyaya
Iyo organic compound ine kemikari formula C7H3BrFN. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: isina ruvara crystalline yakasimba.
-Kunyungudika: inenge 59-61°C.
-Kubikira poindi: inenge 132-133 ℃.
-Kunhuwa chikumbaridzo: Hapana data rakavimbika.
-Solubility: Soluble in organic solvents senge ether, dimethylformamide uye benzene, isinganyunguriki mumvura.
Shandisa:
-is an organic synthesis yepakati iyo inogona kushandiswa kugadzira makomisheni akadai semishonga, mishonga yezvipembenene uye dhayi.
-Inogona kushandiswa seagent yekuunza halogen mumakomisheni anonhuhwirira mune organic synthesis.
Kugadzirira nzira:
-fluorobenzonitrile inogona kugadzirirwa nekuwedzera cuprous bromide (CuBr) kusvika 4-fluorobenzonitrile (C7H4FN).
Zvekuchengetedza
-Inogona kunge inogumbura uye inoparadza, uye kusangana neganda nemaziso zvinogona kukonzera kutsamwa.
-Pfeka midziyo yekudzivirira yakafanira senge magirazi, magurovhosi, uye majasi erabhoritari panguva yekushanda.
-Paunenge uchishandisa nekuchengetedza, zvinodikanwa kutevedzera nzira dzakachengeteka dzekushanda uye chengetedza zvakanaka mumudziyo wakavharwa, kure nekupisa uye oxidizing agents.
-Kana ukafemerwa kana ukapinzwa, tsvaga kurapwa nekukasika. Kana kubata kukaitika, kurumidza kuchenesa nzvimbo yakakanganiswa nemvura yakawanda uye tsvaga rubatsiro rwekurapa.
