Abstract
The present invention provides a technique for producing acetone in a high yield from hydrated ethanol derived from biomass, without requiring a large amount of energy. Hydrated ethanol derived from biomass is heated to a reaction temperature of 400° C. or higher in the presence of a Zr—Fe catalyst, thereby producing acetone. The reaction temperature is preferably from 450 to 550° C., and the Zr—Fe catalyst preferably contains 5 to 10% by mass of Zr. The present invention allows purification of hydrated acetone without requiring purification of the hydrated ethanol.
