CATALYST FOR PRODUCTION OF ACRYLIC ACID FROM GLYCERIN, AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2014/024782

A2

[Problem] To provide a composite metal oxide catalyst which can produce high yields of acrylic acid from glycerin in a one-step reaction, the catalyst comprising at least tungsten, vanadium, niobium and oxygen, and a method for producing same. Also to provide a method for producing acrylic acid from glycerin using the catalyst. [Solution] A composite metal oxide catalyst which is used to produce acrylic acid from glycerin, and which comprises at least tungsten, vanadium, niobium and oxygen. Also provided are: a method for producing the composite metal oxide catalyst, wherein a mixed liquid obtained by mixing a compound comprising at least tungsten, niobium and vanadium with water is subjected to hydrothermal synthesis, thus forming a solid, and the solid is then fired; and a method for producing acrylic acid from glycerin using the catalyst.
