Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C7H7N2O3.
Chilengedwe:
ndi yolimba yokhala ndi mtundu wotumbululuka wachikasu mpaka wachikasu. Ndiwosungunuka kwambiri mu zosungunulira komanso zosasungunuka m'madzi. Imakhala ndi kuyaka kwina, ndipo ikatenthedwa kapena ikakumana ndi lawi lotseguka limatulutsa ma nitrogen oxide (NOx).
Gwiritsani ntchito:
Nthawi zambiri amagwiritsidwa ntchito mu organic synthesis ngati chinthu chapakati chofunikira. Ikhoza kugwiritsidwa ntchito popanga mankhwala a pyridine, monga mankhwala ophera tizilombo, mankhwala ndi utoto. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati ligand pazitsulo zachitsulo.
Njira:
Nthawi zambiri amakonzedwa ndi zomwe 4-methyl-2-nitropyridine ndi sodium hydroxide. Zomwe zimachitika nthawi zambiri zimachitika mu zosungunulira za organic ndipo mankhwalawo amapezeka.
Zambiri Zachitetezo:
Zimawononga thupi la munthu. Kukhudzana ndi khungu kungachititse thupi lawo siligwirizana, ndi inhalation wa fumbi kapena nthunzi ayenera kupewa. Pogwira, njira zodzitetezera ziyenera kuchitidwa, monga kuvala magolovesi, magalasi ndi zovala zodzitetezera. Mukagwiritsidwa ntchito kapena kusungidwa, ziyenera kukhala kutali ndi moto ndi okosijeni. Pankhani ya kutayikira mwangozi, chokani pamalo otayikirawo mwachangu ndikuchita zoyenera kuyeretsa.
