Abstract
Processes and systems for producing N-vinyl carboxylic acid amides are provided herein. According to some aspects of the present invention, a process for producing an N-vinyl carboxylic acid amide is described that eliminates interim solids handling steps during formation of the intermediate compounds, thereby increasing efficiency and reducing cost. The processes and system described herein may be used for the synthesis of N-vinylformamide and its intermediates, including 1-hydroxyethylformamide and 1-alkoxyethylformamide, or for the synthesis of N-methyl,N-vinylformamide and its intermediates, including N-methyl,1-hydroxyethylformamide and N-methyl,1alkoxyethylformamide.
