Mawu Oyamba
2-Chloro-5-bromo-3-nitropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
2-Chloro-5-bromo-3-nitropyridine ndi cholimba choyera chokhala ndi fungo lochepa. Lili ndi kusungunuka kwapakatikati ndipo limasungunuka mu zosungunulira monga ma alcohols ndi ma hydrocarboni a chlorinated.
Ntchito: Itha kugwiritsidwanso ntchito pofufuza komanso kugwiritsa ntchito ma labotale.
Njira:
Njira yokonzekera 2-chloro-5-bromo-3-nitropyridine ingapezeke mwa njira zosiyanasiyana. A njira wamba ndi kukwaniritsa m`malo chlorine ndi bromine powonjezera zotayidwa kolorayidi kapena sulfates zina pansi pa zinthu zamchere wa 3-bromo-5-nitropyridine. Njira zophatikizira zatsatanetsatane zitha kutumizidwa ku mabuku amankhwala kapena zolemba zamaluso.
Zambiri Zachitetezo:
Pawiri iyi ndi amphamvu oxidizing wothandizira mu kaphatikizidwe organic ndipo amafuna chisamaliro pamene kusunga ndi kusamalira moto kapena kuphulika.
Pewani kukhudzana ndi zoyaka, zochepetsera ndi zinthu zoyaka moto.
Zida zodzitetezera zoyenerera monga magolovesi a labu, magalasi, ndi mikanjo ziyenera kuvalidwa pogwira ndi kunyamula.
Pewani kutulutsa mpweya, kumeza, kapena kukhudza khungu.
Iyenera kukhala yowuma ikasungidwa ndikupewa kukhudzana ndi chinyezi mumlengalenga.
Ikatayidwa, iyenera kutayidwa motsatira malamulo amderalo ndipo sayenera kutayidwa kapena kutayidwa mu chilengedwe.
