Kupu Whakataki
Ko te 2-methyl-3-bromopyridine he pūhui waro. E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te puhui:
Kounga:
Ko te 2-Methyl-3-bromopyridine he wai kore tae me te kakara rite ki te pyridine.
Whakamahia:
Ka whakamahia te 2-Methyl-3-bromopyridine hei reagent me te takawaenga i roto i te whakahiato waro.
Tikanga:
I te nuinga o te waa, ka taea te whakarite i te 2-methyl-3-bromopyridine ma te tauhohenga bromination o te pyridine. Ko te tikanga whakahiato e whakamahia nuitia ana ko te tauhohe i te 2-methylpyridine me te bromine i roto i te whakarewa pararopi penei i te chloroform, ma te whakamahi i te konutai hydroxide hei whakakōkī.
Mōhiohio Haumaru: He matū paitini tera pea ka whakaparahako me te kino ki te punaha manawa, kiri me nga kanohi o te tangata. Ko nga taputapu whakamarumaru whaiaro e tika ana penei i nga karapu matū, karu kanohi, me nga kakahu whakamarumaru me mau i te wa e whakamahia ana, me karohia te whakapiri tika. I te wa o te rokiroki me te whakahaere, he mea tika kia aro ki te ahi me te maama, me te whakarite kia mawehe atu i te ahi me nga puna wera. Ko te mea nui, whai i nga tikanga whakahaere haumaru mo nga matū me te whai i nga ture e tika ana.
