Abstract:
A process for preparing an N-vinyl compound by vinylating a compound having at least one nitrogen atom (referred to hereinafter as compound for short) with acetylene, wherein before the vinylation, the compound is reacted with an alkali metal hydroxide in a reaction zone and the mean residence time of the alkali metal hydroxide and of the compound in the reaction zone is less than 6 minutes.
