Versuchsvorschrift

The invention relates to the preparation of tetrahydrofuran. In particular, a mixture of 4-hydroxybutanal and 3-hydroxy-2-methylpropanal is hydrogenated in the presence of a supported transition metal catalyst to give tetrahydrofuran as the major product, and 1,4-butanediol and 2-methyl-1,3-propanediol as minor products.
