2-Hydroxy-6-methyl-5-nitropyridine (CAS# 28489-45-4)

Mawu Oyamba

2-Hydroxy-3-nitro-6-methylpyridine ndi organic pawiri ndi mankhwala formula C7H7N2O3. Zotsatirazi ndikulongosola mwatsatanetsatane za chikhalidwe chake, ntchito, kukonzekera ndi chitetezo:

Chilengedwe:

-Maonekedwe: 2-hydroxy-3-nitro-6-methylpyridine ndi woyera wonyezimira wachikasu wa crystalline ufa.

-Kusungunuka: Kusungunuka kwake m'madzi ndikotsika, kusungunuka muzosungunulira zambiri monga mowa, ether, ketone, ndi zina.

- Malo osungunuka: Malo osungunuka a pawiriwa ndi pafupifupi 194-198 ° C.

-Kukhazikika: kukhazikika pang'onopang'ono kutentha, koma kuyenera kupewedwa ndi kuwala komanso kutentha kwambiri.

Gwiritsani ntchito:

-2-hydroxy-3-nitro-6-methylpyridine amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic ndipo amagwiritsidwa ntchito popanga zinthu zina.

-Itha kugwiritsidwanso ntchito pokonza zida zopangira mphira, mankhwala ophera tizilombo, mankhwala ndi utoto ndi zina.

Njira:

-2-Hydroxy-3-nitro-6-methylpyridine nthawi zambiri imapezeka ndi kaphatikizidwe ka mankhwala. Njira yeniyeni ingapezeke pochita 3-methylpyridine ndi nitric acid kudzera mu nitration reaction, ndiyeno kupyolera mu kuchepetsa ndi hydroxylation reaction.

Zambiri Zachitetezo:

-2-hydroxy-3-nitro-6-methylpyridine ndi mankhwala omwe ali ndi poizoni wina. Tsatirani njira zoyenera zotetezera ma labotale panthawi yogwira ntchito.

-Kulumikizana kapena kutulutsa mpweya wa mankhwalawa kungayambitse mkwiyo komanso kuvulaza thupi la munthu. Kukhudzana ndi khungu, kupuma ndi kuyamwa kuyenera kupewedwa. Magolovesi oteteza akatswiri, maso ndi zida zopumira ziyenera kuvalidwa mukamagwiritsa ntchito.

-Pakakhudza khungu kapena maso, tsukani nthawi yomweyo ndi madzi ambiri ndipo funsani malangizo achipatala mwamsanga.

-Zigawozi ziyenera kusungidwa pamalo otsekedwa, owuma, opanda mpweya wabwino, kutali ndi moto ndi oxidizing agents. Potaya zinyalala, tsatirani malamulo oteteza chilengedwe.
