Kupu Whakataki
Ko te 2,5-Dichloro-3-nitropyridine he pūhui waro. E whai ake nei he kupu whakataki mo ona rawa, ona whakamahinga, tikanga hanga me nga korero haumaru:
Kounga:
- Te ahua: Ko te 2,5-Dichloro-3-nitropyridine he karaihe kore tae ki te kowhai kowhai.
- Wairewa: He whakarewa i roto i nga whakarewa pararopi penei i te waiwaro, te dimethyl ether me te chloroform, engari he iti ake te whakarewa i te wai.
- Pumautanga: He pumau te pūhui i te pāmahana rūma, engari he pahū i te pāmahana teitei, i te whakapā atu rānei ki ngā āpiha hāora kaha.
Whakamahia:
- Pesticides: Ka taea te whakamahi hei patu ngarara, he pai te mana whakahaere ki etahi riha.
Tikanga:
Ko te tikanga whakahiato o te 2,5-dichloro-3-nitropyridine te nuinga o te waa ka uru ki te tauhohenga nitrification me te tauhohenga chlorination. I roto ia ratou, ko te tikanga whakahiato tuku iho ko te whakakini i te 2,5-dichloropyridine me te waikawa nitric i te aroaro o te waikawa sulfuric. Ko tetahi atu tikanga ko te tauhohe i te 2-nitro-5-chloropyridine me te bromide parahi waikawa hei whakaputa i te 2,5-dichloro-3-nitropyridine.
Mōhiohio Haumaru:
- Ko te 2,5-Dichloro-3-nitropyridine he puhui pararopi e tika ana kia whakahaerea ma te tupato kia kore ai e pa ki te kiri, kanohi, me te punaha manawa.
- Mau taputapu whakamarumaru e tika ana, tae atu ki nga kaakahu whakamarumaru, nga karapu, me nga whakangungu kanohi, ina mahi.
- I te wa e mahi ana, karohia te hau hau, te kohu, te kohu ranei me te pupuri i te hau pai.
- Mena ka pa ki te kiri, ki nga kanohi ranei, horoi tonu ki te nui o te wai ka toro atu ki te taote.
- I te wa e penapena ana, me pupuri te 2,5-dichloro-3-nitropyridine ki roto i te waahi maroke, hauhautanga, hau pai, kia matara atu i te mura me te waikura.
