Mawu Oyamba
2,4-Dihydroxypyridine. Lili ndi zotsatirazi:
Maonekedwe: 2,4-Dihydroxypyridine ndi woyera crystalline olimba.
Kusungunuka: Kumasungunuka kwabwino ndipo kumasungunuka m'madzi ndi zosungunulira zosiyanasiyana.
Ligand: Monga ligand for transition metal complexes, 2,4-dihydroxypyridine ikhoza kupanga ma complexes okhazikika ndi zitsulo, zomwe zimagwiritsidwa ntchito kwambiri pokonzekera zopangira ndi zofunikira za organic synthesis.
Corrosion inhibitor: Imagwiritsidwa ntchito ngati imodzi mwazinthu zazitsulo zoletsa dzimbiri, zomwe zimatha kuteteza bwino zitsulo kuti zisawonongeke.
Kukonzekera njira ya 2,4-dihydroxypyridine ndi motere:
Hydrocyanic acid reaction njira: 2,4-dichloropyridine imachitidwa ndi hydrocyanic acid kuti ipeze 2,4-dihydroxypyridine.
Hydroxylation reaction njira: 2,4-dihydroxypyridine imapangidwa ndi zomwe pyridine ndi hydrogen peroxide pansi pa chothandizira cha platinamu.
Information Safety: 2,4-Dihydroxypyridine ndi mankhwala ndipo ayenera kugwiritsidwa ntchito mosamala:
Kawopsedwe: 2,4-Dihydroxypyridine ndi poizoni pazigawo zina ndipo imatha kuyambitsa mkwiyo m'maso ndi khungu mukakumana. Kukhudzana mwachindunji ndi inhalation fumbi lake ayenera kupewa.
Kusungirako: 2,4-Dihydroxypyridine iyenera kusungidwa pamalo ouma, ozizira kuti asakhudzidwe ndi okosijeni ndi ma asidi amphamvu. Pakusungirako, chidwi chiyenera kuperekedwa ku chitetezo cha chinyezi kuti chisawonongeke chifukwa cha chinyezi.
Kutaya zinyalala: Kutaya zinyalala moyenerera, kuyenera kutsatira malamulo ndi malamulo a chilengedwe, kupewa kuwononga chilengedwe.
Mukamagwiritsa ntchito 2,4-dihydroxypyridine, njira zoyendetsera chitetezo ndi njira zodzitetezera, monga kuvala magolovesi ndi magalasi, ziyenera kutsatiridwa kuti zitsimikizire kugwiritsidwa ntchito motetezeka.
