Procedure
A 300 ml stirred Hastelloy C autoclave was charged with 16 g 2,5-dihydrofuran, 80 g water and 5 g of the catalyst described in Example III. The autoclave was heated for 3 hours at 120° C. After cooling the resulting liquid was analysed by means of gas-liquid chromatography. The conversion of 2,5-dihydrofuran amounted to 55% gamma-hydroxy butyraldehyde having been formed with a selectivity of 65%. 2,3-Dihydrofuran, tetrahydrofuran and furan had also been formed in minor amounts.
