The present invention provides a process for producing an N-vinyl compound, which comprises subjecting an N-(-alkoxyalkyl) compound to gas phase intramolecular alcohol elimination to convert said compound to an N-vinyl compound directly in one step, wherein a solid oxide containing phosphorus and an alkali metal and/or an alkaline earth metal is used as a catalyst. This process need not use any solvent or any auxiliary raw material and consequently can produce an N-vinyl compound simply and safely without generating any waste material derived from the auxiliary raw material.
本发明提供了一种生产N-乙烯基化合物的方法,包括将N-(-烷氧基烷基)化合物经气相分子内醇消除反应,直接一步转化为N-乙烯基化合物,其中使用含有磷和碱金属和/或碱土金属的固体氧化物作为催化剂。该方法不需要使用任何溶剂或任何辅助原料,因此可以简单安全地生产N-乙烯基化合物,而不会产生任何与辅助原料相关的废弃物。
