Vorschrift

400 ml of triethyl citrate were hydrogenated at 225° C. and 200 bar together with 1100 ml of tetrahydrofuran and 60 g of catalyst H (3-mm tablets) until the take-up of hydrogen had ceased. The reaction product was freed from tetrahydrofuran and ethanol and distilled under reduced pressure, giving 93.6 g (49%) of 3-(2'-hydroxyethyl)tetrahydrofuran and 6.8 g (3.6%) of 4-hydroxymethyltetrahydropyran.
