Kupu Whakataki

Ko te 4-Fluoroaniline he puhui pararopi. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, nga tikanga whakangao me nga korero haumaru:

 

Kounga:

- Te ahua: Ko te 4-Fluoroaniline he wai kore tae ki te kowhai marama me te kakara o te ammonia rite te aniline.

- Wairewa: 4-Fluoroaniline he whakarewa i roto i nga whakarewa pararopi penei i te benzene, te ethyl acetate me te waro disulfide. He iti ake te wairewa i roto i te wai.

 

Whakamahia:

- Ko te 4-Fluoroaniline e whakamahia nuitia ana i roto i te mara o te whakahiato pararopi, he maha nga wa e whakamahia ana hei rauemi mata, hei takawaenga ranei.

- Ka taea hoki te whakamahi i te 4-Fluoroaniline i roto i te hihiko me te tātari matū.

 

Tikanga:

- He maha nga huarahi hei whakarite i te 4-fluoroaniline. Ko te tikanga noa ko te tauhohe i te nitrobenzene me te konutai fluorohydrochloride ki te whiwhi fluoronitrobenzene, ka huri ki te 4-fluoroaniline ma te tauhohenga whakaheke.

 

Mōhiohio Haumaru:

- 4-He whakapataritari a Fluoroaniline, ka kino pea te kanohi, te kiri, me te punaha manawa. Kia tupato ki te karo i te whakapiri i te wa e whakahaere ana.

- He matū ngiha, karohia te pa ki te mura o te ahi me te wera nui.

- Me tupato ki te whakamahi i nga taputapu pahū me te whakarite kia pai te hau i te wa e rokiroki ana me te whakamahi.

- I te wa e whakahaere ana i te 4-fluoroaniline, me whai nga tikanga taiwhanga tika me nga tikanga whakahaere haumaru.

 

Kia tupato ki te whakamahi i te 4-fluoroaniline me nga puhui e pa ana, ka whai i nga aratohu haumaru taiwhanga, kaihanga ranei.
