Nhanganyaya
2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) is organic compound ine kemikari formula C6H5Br2N. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
2,3-dibromo-5-methylpyridine isimbi yero uye inonhuwa. Iine nzvimbo yekunyunguduka inoita 63-65 madhigirii celsius uye painofashaira ingangoita 269-271 madhigirii celsius. Haina kunyungudika mumvura uye inonyungudika mune organic solvents.
Shandisa:
2,3-dibromo-5-methylpyridine inoshandiswa zvakasiyana-siyana organic synthesis yepakati. Inogona kushandiswa kugadzira mamwe ma organic compounds, akadai seanobva kune biologically inoshanda zvinhu, zvinodhaka uye mishonga yezvipembenene. Inogona zvakare kushandiswa kugadzira zvinhu zvemagetsi zvigadzirwa senge organic light-emitting diodes (OLED) uye organic mabhatiri.
Nzira:
2,3-dibromo-5-methylpyrridine inogona kuwanikwa nekuita 5-methylpyridine ne bromine. 5-Methylpyridine inotanga kupindirana nehydrogen bromide, uye yozoenderera mberi ichiita nemethyl chloride pamberi pechigadziriso chekugadzira chigadzirwa chakananga.
Zvekuchengetedza
2,3-dibromo-5-methylpyrridine inogumbura uye inogona kukonzera kutsamwa kumaziso, ganda uye kufema system. Panguva yekushandiswa, maitiro ekushanda akachengeteka anofanirwa kunyatsocherechedzwa, kusangana kwakananga neganda uye maziso kunofanirwa kudzivirirwa, uye kushanda kunofanirwa kuve nechokwadi munzvimbo ine mhepo inofefetera. Panguva yekubata nekuchengetedza, kutarisirwa kunofanira kutorwa kuti usasangana ne oxidants uye zvinhu zvinopisa zvinopisa kudzivirira njodzi yemoto uye kuputika. Kana ukafemerwa kana kuoneswa mukomboni uyu, tsvaga rubatsiro kuna chiremba nekukasika uye bvunza chiremba ane hunyanzvi.
