Methane → Gamma-Butyrolactone

참여 물질

반응 단계

In a manner similar to that described in Example 1, 10 mL/h of 2,5-dihydrofuran and 9 mL/h of water were passed over 73 g of a rhenium-on-activated charcoal catalyst (rhenium content: 6 wt %, calculated as Re; prepared by impregnation of 4 mm activated charcoal extrudates with an aqueous dirhenium heptoxide Re2O7 solution; drying at 120° C.; reduction in a manner similar to that described in Example 1). At a conversion of 99%, γ-butyrolactone was formed with a selectivity of 91% (2,3-dihydrofuran: 0.5%; furan: 1%; tetrahydrofuran: 5%; n-butanol: 1%; remainder: small amounts of various non-analyzed low-boiling fractions).
