Mawu Oyamba
(1H) -one (1H) -one) ndi organic pawiri ndi mankhwala chilinganizo C6H7NO2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
(1H) -imodzi ndi crystalline yoyera yolimba, yopanda fungo. Ndiwokhazikika pa kutentha wamba, koma akhoza kuwola pa kutentha kwambiri. Malo ake osungunuka ndi pakati pa 140-144 madigiri Celsius.
Gwiritsani ntchito:
(1H) -imodzi ili ndi mitundu ingapo ya ntchito mu organic synthesis. Angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic kwa synthesis wa mankhwala ena, monga mankhwala, utoto ndi mankhwala. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chitsulo chophatikizira zitsulo kuti zitheke.
Njira Yokonzekera:
Pali njira ziwiri zazikulu zokonzekera (1H) -imodzi. Chimodzi ndikuyambitsa gulu la hydroxyl ndi gulu la methyl mu mphete ya pyridine ndi alkylation ya gulu la hydroxyl la picoline. Njira ina ndikuchita hydroxyl alkylation reaction pa mphete ya pyridine kuyambitsa gulu la hydroxyl ndi gulu la methyl. Njira yeniyeni yokonzekera ikhoza kusankhidwa malinga ndi zosowa ndi zikhalidwe.
Zambiri Zachitetezo:
(1H) -imodzi imakhala yochepa kwambiri koma iyenera kuchitidwa mosamala. Pogwira ntchito, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi khungu ndi maso, ndikuwonetsetsa kuti ntchitoyo ili pamalo abwino kwambiri. Ngati mwangozi kukhudzana, ayenera yomweyo muzimutsuka ndi madzi ndi yake mankhwala. Kuphatikiza apo, iyenera kusungidwa mu chidebe chotsekedwa, kutali ndi moto ndi oxidizing agents.
Chonde dziwani kuti mukamagwiritsa ntchito ndikugwiritsa ntchito mankhwala aliwonse, muyenera kutsatira njira zolondola za labotale, ndikulozera ku pepala lachitetezo (SDS) la chinthucho komanso chitsogozo cha mabungwe akatswiri.
