Nhanganyaya
2-methyl-3-bromopyridine isanganiswa yeorganic. Inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomboni:
Hunhu:
2-Methyl-3-bromopyridine imvura isina ruvara ine kunhuhwirira kwakafanana nepyridine.
Shandisa:
2-Methyl-3-bromopyridine inowanzoshandiswa se reagent uye yepakati mune organic synthesis.
Nzira:
Kazhinji, kugadzirira kwe2-methyl-3-bromopyridine kunogona kuwanikwa nebromination reaction yepyridine. Iyo inowanzoshandiswa nzira yekugadzira ndeyekuita 2-methylpyridine ine bromine mune organic solvent senge chloroform, uchishandisa sodium hydroxide sechinhu chinokonzeresa.
Ruzivo Rwekuchengetedza: Chinhu chine muchetura chinogona kukonzera kushatirwa uye kukuvadza kuhurongwa hwekufema kwevanhu, ganda uye maziso. Midziyo yekuzvidzivirira yakafanira yakadai semagirovhosi emakemikari, magirazi emaziso, uye zvipfeko zvinodzivirira zvinofanira kupfekwa panguva yekushandiswa uye kuonana kwakananga kunofanira kudziviswa. Panguva yekuchengetedza uye kubata, zvinofanirwa kutarisisa kumoto uye chiedza, uye kuve nechokwadi kuti inochengetedzwa kure nemoto uye kupisa zvitubu. Chinonyanya kukosha, tevera nzira dzakachengeteka dzekushanda kwemakemikari uye tevera mirairo yakakodzera.
