乙炔法合成醋酸乙烯高活性催化剂的研究

Study on High Activity Catalyst for Synthesis of Vinyl Acetate from Acetylene and Acetic Acid

研制了一种加助剂的醋酸锌/活性炭新催化剂(GC-87-43)在乙炔法合成醋酸乙烯(VAc)反应中,该催化剂比湖南维尼纶厂工业用 GC-湖维倦化剂生产能力高17-21%左右,其稳定性和生成的副产物无明显差别。

A new zinc acetate/activated carbon GC-87-43 catalyst containing additiveswas prepared.As compared with the GC-F.V catalyst,which is being employedby Hunan Polyvinyl Alcohol Fibre Factory,the activity of GC-87-43 catalystenhances by 17—21%.Its stability and side products during reaction are the sameas those of GC-F.V catalyst.
