Mawu Oyamba
2-Bromo-6-chloropyridine ndi organic pawiri.
Ubwino:
2-Bromo-6-chloropyridine ndi kristalo woyera wolimba ndi kukoma kowawa komanso fungo lamphamvu. Sipasungunuke m'madzi kutentha, koma sungunuka mu zosungunulira za organic monga ethanol, ether ndi benzene. Imakhala ndi kukhazikika kwamafuta ndi mankhwala.
Gwiritsani ntchito:
Monga organic wapakatikati, 2-bromo-6-chloropyridine ali osiyanasiyana ntchito mu synthesis mankhwala. Komanso, angagwiritsidwe ntchito ngati chothandizira, zosungunulira ndi reagent, etc.
Njira:
2-Bromo-6-chloropyridine nthawi zambiri imakonzedwa ndi njira zopangira mankhwala. Njira yodziwika bwino ndikuchita 2-chloro-6-bromopyridine ndi thionyl chloride kapena dimethyl sulfate ndikutenthetsa pansi pamikhalidwe yamchere kuti ipange 2-bromo-6-chloropyridine.
Zambiri Zachitetezo:
2-Bromo-6-chloropyridine ndi mankhwala omwe ali ndi poizoni wina kwa anthu. Mukamagwiritsa ntchito, kukhudzana mwachindunji ndi khungu ndi maso kuyenera kupewedwa kuti mupewe kupuma kapena kumeza. Ayenera kugwirira ntchito pamalo opumira mpweya wabwino ndi kuvala zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera. Ngati mwakumana ndi vutoli mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala. Pakusungirako ndi kunyamula, kukhudzana ndi malawi otseguka, magwero otentha ndi okosijeni kuyenera kupewedwa kupewa ngozi zamoto ndi kuphulika.
