Nhanganyaya
2,5-Dibromo-4-methylpyridine is an organic compound. Iyi inotevera sumo yakadzama kune zvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomponi iyi:
Hunhu:
2,5-Dibromo-4-methylpyridine yakasimba uye isina ruvara kune yero yecrystalline mafomu. Iine solubility yakasimba uye inonyungudika mune zvakawanda organic solvents. Ikomboni isina kugadzikana inoputsika nyore muchiedza chezuva.
Shandisa:
Mushonga uyu unowanzo shandiswa seyakagadzirwa uye reagent mune organic synthesis.
Nzira:
2,5-Dibromo-4-methylpyridine inonyanya kugadzirirwa nekuita kwebrominated p-toluene uye pyridine. P-toluene inopindirana ne cuprous bromide kuita 2-bromotoluene, iyo inobva yasangana ne pyridine pasi pe acid catalysis kuburitsa chigadzirwa chekupedzisira.
Zvekuchengetedza
2,5-Dibromo-4-methylpyridine inoda kubatwa nekuchenjerera sezvo iine chepfu. Kuchengetedza kunofanira kutorwa kuti usasangana neganda, maziso, uye nzira yekufema panguva yekushanda. Midziyo yekuzvidzivirira yakafanira senge magurovhosi, ziso rekudzivirira, uye masks ekudzivirira zvinofanirwa kupfekwa kana zvichishandiswa murabhoritari. Kana ichichengetwa uye ichibatwa, inofanira kuchengetwa kure nezvinhu zvinopisa uye oxidizing agents. Kana chinhu chakamedzwa kana kufemerwa nekukanganisa, kurapwa kunofanirwa kutsvagwa nekukasika. Pakurasa marara, mitemo yenzvimbo inofanira kuteverwa uye tsvina inofanira kuraswa zvakanaka kudzivirira kusvibiswa kwemhoteredzo.
