Nhanganyaya
Iyo organic compound ine kemikari formula C6H5BrN2O2. Inotevera rondedzero yezvimwe zvezvivakwa zvayo, kushandiswa, nzira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: White crystalline yakasimba.
-Kunyungudika nzvimbo: anenge 130-132 madhigirii Celsius.
-Kubikira nzvimbo: inenge 267-268 madhigirii Celsius.
-Solubility: Soluble mune mamwe organic solvents.
Shandisa:
-inogona kushandiswa kune organic synthesis reaction, senge cyanidation reaction, nitration reaction.
-Iyo inowanzoshandiswa sechinhu chakakosha chepakati chekubatanidza kwemamwe organic compounds.
-Mumunda wekutsvaga zvinodhaka, inoshandiswawo kugadzirira mamwe mishonga inorwisa mabhakitiriya.
Nzira: The synthesis ye
-inowanzo kuwanikwa ne nitration ye pyridine. Pyridine inotanga kubatwa ne nitric acid uye concentrated sulfuric acid, yozobatwa nehydrogen bromide solution kuti iwane chinonangwa chigadzirwa.
Zvekuchengetedza
-icho chiumbwa chine mwero wakati wengozi. Pfeka magirovhosi ekudzivirira uye magirazi panguva yekushanda kudzivirira kusangana kwakananga neganda nemeso.
-Dzivisa kufema guruva kana gasi uye shanda munzvimbo ine mhepo inofefetera murabhoritari.
-Mushonga unogona kunge uine teratogenic, carcinogenic kana zvimwe zvinokuvadza pavanhu, saka nzira dzekuchengetedza dzakakodzera dzinofanira kunyatsoteverwa. Mukuonana kana inhalation mushure mekuwedzeredza, kunofanirwa kuve nenguva yekurapa kurapwa.
