In a manner similar to that described in Example 1, 19 mL/h of 2,5-dihydrofuran and 11 mL/h of water were passed over 142 g of the catalyst described in Example 2. At a conversion of 99.7% γ-butyrolactone was obtained with a selectivity of 89% (2,3-dihydrofuran: 0.13%; furan: 3.9%; tetrahydrofuran: 5%; n-butanol: 1.7%; remainder: small amounts of various non-analyzed low-boiling fractions).
