Propionamide (CAS: 79-05-0) yog monocarboxylic acid amide tau los ntawm kev sib xyaw ua ke ntawm propionic acid nrog ammonia.Siv rau cov organic synthesis.Rau cov synthesis ntawm midcamycin tshuaj.
Qhov tshwm sim los ntawm cov tshuaj tiv thaiv ntawm propionic acid nrog ammonia.Ammonia gas tau nkag mus rau hauv lub reactor uas n-propionic acid tau ntxiv.Thaum kub nce mus txog 140 ℃, tag nrho cov propionic acid tsim ammonium propionate, thiab cov ammonia ntws tau nres.Cov crystals tau txias, lim kom muab cov khoom nyoos, thiab recrystallized los ntawm ethanol los muab cov khoom tiav.
