Kupu Whakataki

1-Bromopentane, e mohiotia ana ko bromopentane. E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te 1-bromopentane:

 

Kounga:

Ko te 1-Bromopentane he wai kore tae me te kakara kaha. Ka whakarewahia i roto i nga whakarewa pararopi penei i te waiwaro, te etera, me te benzene, karekau e rewa ki te wai. Ko te 1-Bromopentane he pūhui organohalogen he āhuatanga haloalkane nā te noho o te ngota bromine.

 

Whakamahia:

Kei te whakamahia whānuitia te 1-Bromopentane hei reagent brominated i roto i te whakahiato waro. Ka taea te whakamahi i roto i nga tauhohenga esterification, etherification tauhohenga, tauhohe whakakapinga, aha atu. Ka whakamahia ano hei whakakorikori, whakarewa ranei i etahi tauhohenga whakahiato waro.

 

Tikanga:

Ka taea te whakarite i te 1-Bromopentane ma te tauhohenga o te ethyl bromide me te acetate pāhare pāporo, a ko te tikanga ka mahia i te pāmahana teitei. Ina tauhohe te ethyl bromide ki te acetate pāhare pāporo, ka tukuna he tauhohenga whakakapinga o te acetate pāhare pāporo, ka whakakapihia te roopu ethyl ki te ngota bromine, ka hoatu he 1-bromopentane. Ko tenei tikanga no te huarahi waihanga e whakamahia ana mo te whakarite i te 1-bromopentane.

 

Mōhiohio Haumaru:

Ko te 1-Bromopentane he whakapataritari me te paitini. Ko te pa atu ki te kiri ka whakapataritari, ka whakapouri hoki i nga kanohi me te punaha manawa. Ko te rongonga mo te wa roa ki te whakamahutanga ranei o nga kukū teitei o te 1-bromopentane ka raru pea nga whekau penei i te punaha nerve matua me te ate. Kia kaha ki te mahi i roto i te waahi whai hau me te karo i te pa ki te ahi, na te mea he muramura te 1-bromopentane.
