Abstract

In the process for preparing formamide by reaction of ammonia and carbon monoxide in the presence of at least one catalyst, sodium diformylamide is used as catalyst. If sodium methoxide is used as further active component, sodium diformylamide can be formed from this. In this process, sodium diformylamide is a particularly active and stable catalyst which can be recycled.
