Versuchsvorschrift

400 ml of triethyl citrate were hydrogenated at 175° C. and 50 bar together with 1100 ml of tetrahydrofuran and 60 g of catalyst F (4-mm tablets) until the take-up of hydrogen had ceased. The reaction product was freed from tetrahydrofuran and distilled under reduced pressure, giving 101 g (39%) of ethyl tetrahydrofurfurylacetate and 57 g (30%) of 3-(2'-hydroxyethyl)tetrahydrofuran.
