反応手順
In a manner similar to that described in Example 1 10 mL/h of 2,3-dihydrofuran and 8 mL/h of water were passed at 220° C. in a stream of carrier gas comprising 13 L/h of hydrogen over 47 g of the rhenium-on-activated charcoal catalyst described in Example 5 (reactor volume: 100 mL). At a conversion of 99.5%, γ-butyrolactone was formed with a selectivity of 98% (tetrahydrofuran: 0.3%; 4-hydroxybutyraldehyde: 0.5%; remainder: small amounts of various non-analyzed low-boiling fractions).
