실험 절차
400 ml of triethyl citrate were hydrogenated at 175° C. and 10 bar together with 1100 ml of tetrahydrofuran and 60 g of catalyst G (4-mm tablets) until the take-up of hydrogen had ceased. The reaction product was freed from ethanol and distilled under reduced pressure, giving 193 g (45%) of triethyl propane-1,2,3-tricarboxylate.
