Kupu Whakataki

Ko te Bromoacetyl bromide he puhui waro. E whai ake nei he kupu whakataki mo nga taonga, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te bromoacetyl bromide:

 

Kounga:

Te ahua: Ko te Bromoacetyl bromide he wai kore tae ki te kowhai kowhai.

Wairewa: He ngawari te whakarewa i roto i nga whakarewa pararopi, engari he uaua ki te memeha ki te wai.

Te koretake: Ka pirau te Bromoacetyl bromide i te wera nui, i te makuku ranei hei whakaputa hau paitini.

 

Whakamahia:

Ka whakamahia te Bromoacetyl bromide hei reagent brominating i roto i te whakahiato waro, a ka taea te whakamahi hei reagent brominating mo nga pūhui i ahu mai i te ketone.

Ka taea hoki te whakamahi i roto i te whakaritenga o te whakarewa, te whakakorikori me te hau.

 

Tikanga:

Ka taea te whakarite Bromoacetyl bromide ma te tauhohenga o te waikawa bromoacetic me te ammonium bromide i roto i te waikawa acetic:

CH3COOH + NH4Br + Br2 → BrCH2COBr + NH4Br + HBr

 

Mōhiohio Haumaru:

Me whakahaere te Bromoacetyl bromide me nga tikanga whakamarumaru, penei i te mau karaehe whakamarumaru, nga karapu me nga koti taiwhanga.

He puhui puhoi ka pa ki te kiri, ki nga kanohi ranei. Horoihia ki te nui o te wai i muri tonu i te rongonga me te rapu rongoa.

I te wa e rongoa ana me te whakamahi i te bromoacetyl bromide, me noho ke atu i nga puna ahi me te mura o te ahi, me te karo i nga taiao teitei o te pāmahana kia kore ai e pahū me te tuku hau kino.
