Abstract:

Vinyl acetate is an important industrial organic raw material. There are two main vinyl acetate production processes, i.e. acetylene method and ethylene method. The technological progress in vinyl acetate production process is introduced, including the latest achievements in reaction kinetics study and reaction process, catalyst preparation process and reactor structure optimization. The advantages and disadvantages of the two technological routes are compared in terms of technical difficulty and production cost. The process characteristics of two ethylene methods including Vantage Process and Leap Process and their breakthroughs in catalyst and reactor research and development are mainly introduced. The problems in China’s vinyl acetate industry are analyzed, and the future research and development direction of vinyl acetate process is prospected.

Key words: acetylene method, ethylene method, vinyl acetate, technological progress, catalyst research and development
