Acetamide is not extremely combustible and does release irritating fumes when ignited. It is toxic by inhalation (of dust), ingestion, skin and eye contact. Skin or eye contact may cause redness and pain.
Dissolve 5 g of impure acetamide in a mixture of 5 ml of benzene (CAUTION) and 1,5 ml of dry ethyl acetate; warm on a water bath until all is dissolved and cool rapidly in ice or cold water.
The unpleasant odour is absent and the pure acetamide melts at 81
