Kupu Whakataki
Ko te 2-Fluoro-5-nitropyridine (2-Fluoro-5-nitropyridine) he pūhui waro me te tauira matū C5H3FN2O2. Ko nga korero e whai ake nei mo tona ahuatanga, te whakamahinga, te whakarite me nga korero haumaru:
Taiao:
-Te ahua: 2-Fluoro-5-nitropyridine he toka ma ki te kowhai kowhai.
-Solubility: Ka taea te rewa i roto i te maha o nga whakarewa pararopi, penei i te ethanol, te dimethylformamide me te dichloromethane.
-Ira whakarewa: Ko tona ira whakarewa he tata ki te 78-81 nga nekehanga Celsius.
Whakamahia:
- Ko te 2-Fluoro-5-nitropyridine he takawaenga whakahiato pararopi whai hua, he mea nui ki te hanga i nga raau taero me nga pesticides.
-Ka taea te whakamahi ki te whakahiato i nga momo puhui hohe koiora, penei i te rongoa, te tae me te paninga.
Tikanga Whakaritenga:
- Ko te 2-Fluoro-5-nitropyridine i te nuinga o te wa ka mahia e te fluorination me te nitration o te pyridine.
-Ko te tikanga whakarite motuhake ko te tauhohe i te pyridine ki te hauwai fluoride me te haukinia fluoride ki te whiwhi 2-fluoropyridine. Ka tauhohehia te 2-fluoropyridine ki te waikawa nitric hei hoatu 2-Fluoro-5-nitropyridine.
Mōhiohio Haumaru:
- Ko te 2-Fluoro-5-nitropyridine he puhui pararopi me tetahi tohu o te kino. I roto i te tukanga o te mahi, he mea tika ki te whai i nga ture whakahaere haumaru e tika ana.
-Kei te whakapataritari ki te kiri me nga kanohi, no reira me mahi nga tikanga whakamarumaru ina kitea ana, penei i te mau karawhiu tiaki me nga karaehe.
-Mena ka horomia noa, ka ngotea ranei, rapua te rongoa me hoatu nga tikanga awhina tuatahi.
-I te wa o te rokiroki, me penapena te 2-Fluoro-5-nitropyridine ki tetahi wahi maroke, hauhautanga, kia matara atu i te ahi me te whakangao.
