Abstract:
Provided is a method for producing γ-valerolactone that is hard to elute metallic components and has high productivity. γ-Valerolactone is synthesized by bringing a levulinic acid compound represented by the formula (1) (where R represents a hydrogen atom, a linear alkyl group of 1 to 6 carbon atoms or a branched alkyl group of 3 to 6 carbon atoms) into contact with hydrogen in the presence of a catalyst in which two or more different kinds of metals of Group VIII to Group X metals in the periodic table are supported on a support.

Claim (Index 5):
The method for producing \u03b3-valerolactone according to  claim 1 , wherein a reaction temperature is 50\u00b0 C. to 220\u00b0 C. and a reaction pressure is, in terms of hydrogen partial pressure, ordinary pressure to 10 MPa.
