Kupu Whakataki
Ko te waikawa 5-fluoro-2-nitrobenzoic(5-fluoro-2-nitrobenzoic acid) he pūhui waro me te tātai matū C7H4FNO4. Ko nga korero e whai ake nei mo tona ahuatanga, te whakamahinga, te whakarite me nga korero haumaru:
Taiao:
-Te ahua: Ko te waikawa 5-fluoro-2-nitrobenzoic he ma, he ma ranei te paura tioata.
-Ira whakarewa: Tata ki te 172°C.
-Warewa: He iti te wairewa ki te wai, ka whakarewahia ki etahi whakarewa waro penei i te waipiro me te hākawa.
Whakamahia:
-Ko te whakahiato matū: Ko te waikawa 5-fluoro-2-nitrobenzoic he takawaenga whakahiato pararopi e whakamahia nuitia ana, ka taea te whakamahi ki te whakahiato i etahi atu puhui waro, penei i te raau taero, te pesticides me te waikano.
-Nga kaupapa rangahau Putaiao: Na tona hanganga kei roto nga roopu fluorine me te nitro, ko te waikawa 5-fluoro-2-nitrobenzoic he tohu matū motuhake ka taea te whakamahi mo nga rangahau me nga whakamatautau taiwhanga.
Tikanga:
Ko te tikanga whakarite o te waikawa 5-fluoro-2-nitrobenzoic i te nuinga o te waa ka riro ma te tauhohenga fluorination o te waikawa 2-nitrobenzoic.
1. Tuatahi, ka tauhohehia te waikawa 2-nitrobenzoic ki tetahi kaihoko fluorinating (pērā i te hauwai pūkōwhai, konutai pūkōwhai rānei).
2. I muri i te tauhohenga, ka whiwhi hua waikawa 5-fluoro-2-nitrobenzoic.
Me tohu ko te wa e whakarite ana, me whakamahi nga tikanga whakahaere whakamatautau me nga tikanga haumaru hei whakarite i te haumaru o te whakamatautau.
Mōhiohio Haumaru:
- Ko te waikawa 5-fluoro-2-nitrobenzoic e kiia ana he puhui ahua haumaru i raro i nga tikanga whanui, engari me ata whakahaere me te whai i nga tikanga whakamatautau tika.
-I te pa atu ki tenei puhui, me karo te pa ki te kiri me te ngohanga o te puehu.
-I roto i te whakamahinga me te tukanga rokiroki, me tiaki tika nga taputapu taiwhanga, me te whai ki nga aratohu haumaru e tika ana.
-Mena ka puta he aitua, e whakapaetia ana ka paihana, me rapu wawe te rongoa me te kawe mai i te pepa raraunga haumaru o te puhui.
