Mawu Oyamba
3-Bromo-5-methyl-pyridine ndi mankhwala omwe ali ndi mankhwala a C6H6BrN ndi molekyulu yolemera 173.03g / mol. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Mawonekedwe: Amadzimadzi achikasu otumbululuka kapena olimba kwambiri.
-Kusungunuka: Kusungunuka mu zosungunulira zambiri za organic, monga mowa, etha ndi ma hydrocarboni a chlorinated.
- Malo osungunuka: pafupifupi 14-15 ℃.
- Malo otentha: pafupifupi 206-208 ℃.
- Kachulukidwe: pafupifupi 1.49g/cm³.
-Kununkhira: Kumakhala ndi fungo lapadera komanso lopatsa chidwi.
Gwiritsani ntchito:
- 3-Bromo-5-methyl-pyridine amagwiritsidwa ntchito ngati gawo lapakati pakupanga kwachilengedwe ndipo angagwiritsidwe ntchito pokonzekera mankhwala ena achilengedwe, monga mankhwala, mankhwala ophera tizilombo ndi utoto.
-Itha kugwiritsidwanso ntchito ngati reagent mu kafukufuku ndi labotale.
Njira Yokonzekera:
- 3-Bromo-5-methyl-pyridine ikhoza kupangidwa ndi njira zosiyanasiyana, imodzi yomwe imagwiritsidwa ntchito powonjezera methylating agent (monga methyl magnesium bromide) ku 3-bromopyridine.
Zambiri Zachitetezo:
- 3-Bromo-5-methyl-pyridine iyenera kugwiritsidwa ntchito motsatira njira zoyenera zotetezera, monga kuvala zida zodzitetezera zomwe zimafunikira m'ma laboratories amankhwala.
-Zitha kuyambitsa kuyabwa komanso kuwonongeka kwa maso, khungu komanso kupuma. Tsukani malo omwe akhudzidwa mwamsanga ndipo funsani thandizo lachipatala ngati kuli kofunikira.
-Posunga ndikugwira, ziyenera kusungidwa m'chidebe chotsekedwa, kutali ndi moto komanso kutentha kwakukulu.
-Potaya zinyalala, tsatirani malamulo akumaloko ndikutsata njira zoyenera zotetezera chilengedwe.
