<P>PROBLEM TO BE SOLVED: To produce a catalyst suitable for producing unsaturated ketones and to provide a method for efficiently producing the unsaturated ketones from corresponding hydroxy ketones. <P>SOLUTION: Hydroxy ketone can be efficiently dehydrated by using a metal oxide excluding an alkaline earth oxide and an alkaline earth metal oxide, for example, by using a titanium oxide, a titanium oxide-metal oxide composite material, silicon oxide and a silicon oxide-metal oxide composite material as a catalyst. Namely, unsaturated ketones can be efficiently produced. Especially, it is suitable to produce methyl vinyl ketone from 1-hydroxy-3-butanone. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
