Ko te 2,5-Dibromo-6-methylpyridine he pūhui waro. E whai ake nei he kupu whakataki mo ona rawa, ona whakamahinga, tikanga whakarite me nga korero haumaru:
Āhuatanga:
Te ahua: Ko te 2,5-Dibromo-6-methylpyridine he totoka kore tae, he kowhai marama ranei.
Wairewa: He whakarewa i roto i etahi whakarewa pararopi, penei i te waiwaro, te etera me te ester.
Whakamahinga: Ka taea te whakamahi i roto i te whakahiato waro hei whakauru i nga roopu methyl, hei reagent bromination ranei.
Tikanga takahanga:
Ko te tikanga whakarite o te 2,5-Dibromo-6-methylpyridine ka taea e nga waahanga e whai ake nei:
Whakarewahia te 2,6-dimethylpyridine ki te waipiro, te ketone, te whakarewa hākawa ranei.
Tāpirihia he bromine, he tauhohenga bromination ranei ki te otinga tauhohenga.
Ka mahia te tauhohenga i te pāmahana e tika ana, a ko te nuinga o te waa ka roa ake te wa.
I muri i te whiwhinga o te hua, ka taea te tango me te pure ma te whakamaarama me nga tikanga whakamaaramatanga.
Nga korero haumaru:
Ko te 2,5-Dibromo-6-methylpyridine he paitini ki tetahi waahanga ka whakapataritari i te kiri me nga kanohi. Me karohia te whakapiri tika. I te wa e mahi ana, me mau nga taputapu whakamarumaru e tika ana, penei i nga karapu me nga karaehe. Me whakahaere nga mahi i roto i te waahi pai-hau kia kore ai e pangia nga hau kino. I te tukunga o te para, me whakahaere i runga i nga tikanga o te rohe. I te wa e whakamahi ana, e rongoa ana ranei i te 2,5-dibromo-6-methylpyridine, me tupato ki te karo i te ahi me te wera nui.
