実験手順
In a manner similar to that described in Example 5 14 mL/h of 2,5-dihydrofuran and 24 mL/h of water were passed over the rhenium-on-activated charcoal catalyst at 220° C. At quantitative conversion, γ-butyrolactone was formed with a selectivity of 87% (furan: 2.5%; tetrahydrofuran: 9%; n-butanol: 1%; remainder: various non-analyzed low-boiling fractions).
