Participants

Reaction Steps

A mixture of butyraldoxime (8.7 g., 0.1 mole) and diacetyl monoxime (10.1 g., 0.1 mole) was warmed to obtain a homogeneous solution. After standing for 2 days at room-temperature, the mixture was heated on the steam-bath for 3 hr., and then diluted with ether (500 ml), the tan solid separated was removed by filtration (16.7 g.) and recrystallised from ethanol (95%) having a melting point 174°-175°C
