Ethanal and propanal test
WebOpen ethanal bottles very cautiously in a fume cupboard, after cooling in an ice bath. Avoid using ethanal if at all possible; use propanal or butanal instead. Do not use near naked flames; if heating is necessary, use an electrically heated water bath or hot water from a kettle. Assessing the risks WebIodoform test. Aldehydes and ketones having at least one methyl group linked to the carbonyl carbon atom responds to the iodoform test. Ethanal having one methyl group linked to the carbonyl carbon atom responds to this test. But propanal does not have a methyl group linked to the carbonyl carbon atom and thus, it does not respond to this state.
