Kupu Whakataki

He pūhui waro te propilate bromide. E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te propionyl bromide:

 

Kounga:

1. Te ahua me nga ahuatanga: Ko te Propionyl bromide he wai kore tae me te kakara reka.

2. Wairewa: Ko te Propionyl bromide he whakarewa i roto i nga whakarewa pararopi, penei i te ether me te benzene, me te kore e rewa ki te wai.

3. Pumautanga: Ko te Propionyl bromide he kore e mau, he ngawari hoki te whakamaarama e te wai hei whakaputa acetone me te hauwai bromide.

 

Whakamahia:

1. Te whakahiato waro: Ko te propionyl bromide he reagent whakahiato waro nui ka taea te whakamahi ki te whakauru i nga roopu propionyl me nga ngota bromine.

2. Ētahi atu whakamahinga: Ka taea hoki te whakamahi propionyl bromide ki te whakarite i nga pärönaki acyl bromide, whakakorikori mo te whakahiato waro me nga takawaenga i roto i te matū reka.

 

Tikanga:

Ka taea te whakarite i te propionyl bromide ma te tauhohenga o te acetone me te bromine. Ko nga tikanga tauhohenga ka taea te whakahaere i te pāmahana rūma ma te whakamahana ranei.

 

Mōhiohio Haumaru:

1. Ko te Propionyl bromide he tino whakapataritari, a tera pea ka pa ki te kiri me nga kanohi, no reira me tupato kia kore e pa atu.

2. Ko te Propionyl bromide e whakaraerae ana ki te makuku hauwai me te pupuri ki te wahi matao, maroke, kia hiritia.

3. Me mau tonu te pai o te hau i te wa e whakamahia ana kia kore ai e ngotea tona kohu.

4. Kia mau ki nga tikanga haumaru e tika ana i te wa e rokiroki ana, e kawe ana, e whakahaere ana, penei i te mau karapu whakamarumaru, moata me nga kakahu whakamarumaru.
