Abstract

1,4-butanediol and THF are prepared from furan by a process which comprises converting furan in the presence of water and hydrogen but in the absence of a water-soluble acid in a single stage over a hydrogenation catalyst, the hydrogenation catalyst containing at least one element of subgroup I, V, VI, VII or VIII in the form of a compound or in elemental form and the restriction that the catalyst does not contain nickel alone being applicable.
