Ngozi ndi Chitetezo

Zizindikiro Zowopsa R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu.
R25 - Poizoni ngati atamezedwa
R40 - Umboni wochepa wa zotsatira za carcinogenic
Kufotokozera Zachitetezo S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala.
S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.)
S37/39 - Valani magolovesi oyenera komanso chitetezo chamaso / kumaso
S28A -
S36 - Valani zovala zoyenera zodzitetezera.

2-Amino-3-hydroxypyridine (CAS# 16867-03-1) chiyambi

2-Amino-3-hydroxypyridine. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:

Ubwino:
2-Amino-3-hydroxypyridine ndi organic pawiri ndi woyera crystalline maonekedwe kuti sungunuka m'madzi ndi zina organic solvents.
Ndi maziko amphamvu omwe amalepheretsa ma asidi ndikupanga mchere wofananira. Ili ndi pH yayikulu ndipo imagwiritsidwa ntchito nthawi zambiri pochita zinthu zopanda pake.

Kagwiritsidwe: Itha kugwiritsidwanso ntchito pokonza zinthu zosiyanasiyana monga utoto, zokutira, ndi zofewa.

Njira:
Kukonzekera kwa 2-amino-3-hydroxypyridine nthawi zambiri kumayambira ku pyridine. Choyamba, pyridine imakhudzidwa ndi mpweya wa ammonia kupanga 2-aminopyridine. Ndiye, pamaso pa sodium hydroxide, anachita aumbike kupanga 2-amino-3-hydroxypyridine.

Zambiri Zachitetezo:
2-Amino-3-hydroxypyridine ikhoza kukhala ndi zotsatira zokhumudwitsa pa maso, khungu, ndi kupuma. Mukamagwiritsa ntchito, chonde sungani njira zodzitetezera zoyenera, monga kuvala magolovesi, magalasi otetezera, ndi zina zotero. Chonde sungani chigawocho moyenera, kutali ndi moto ndi zipangizo zoyaka.
