Versuchsvorschrift
400 ml of triethyl citrate were hydrogenated at 200° C. and 200 bar together with 1100 ml of ethanol and 60 g of catalyst B (4-mm pellets) until the take-up of hydrogen had ceased. The reaction product was freed from ethanol and distilled under reduced pressure, giving 80 g (42%) of 3-(2'-hydroxyethyl)tetrahydrofuran and 1.8 g (1%) of 4-hydroxymethyltetrahydropyran.
