Mawu Oyamba
N-Methylacetamide ndi organic pawiri. Ndi madzi opanda colorless amene sungunuka m'madzi ndi zambiri organic solvents pa firiji.
N-methylacetamide imagwiritsidwa ntchito popanga organic synthesis ngati zosungunulira komanso zapakatikati. N-methylacetamide itha kugwiritsidwanso ntchito ngati dehydrating agent, ammoniating agent, and carboxylic acid activator mu organic synthesis reaction.
Kukonzekera kwa N-methylacetamide kumatha kupezedwa ndi zomwe acetic acid ndi methylamine. Njira yeniyeni ndikuchitapo kanthu kwa acetic acid ndi methylamine pa chiwerengero cha molar cha 1: 1 pansi pazifukwa zoyenera, ndiyeno distillation ndi kuyeretsedwa kuti mupeze mankhwala omwe mukufuna.
Chidziwitso chachitetezo: Nthunzi ya N-methylacetamide imatha kukwiyitsa maso ndi kupuma, ndipo imakhala ndi vuto locheperako mukakumana ndi khungu. Pogwiritsira ntchito kapena kugwiritsira ntchito, njira zodzitetezera ziyenera kuchitidwa, monga kuvala magalasi otetezera, magolovesi otetezera, ndi zina zotero. N-methylacetamide imakhalanso ndi poizoni ku chilengedwe, choncho m'pofunika kutsatira malamulo okhudzana ndi chitetezo cha chilengedwe ndi kumvetsera. kutaya zinyalala moyenera. Mukamagwiritsa ntchito ndikusunga, njira zoyendetsera chitetezo ndi malangizo ogwiritsira ntchito ziyenera kutsatiridwa.
