Versuchsvorschrift

A mixture of 1,1,1-tris(benzyloxyethoxymethyl)ethane (13.9 g, 0.027 mol) and palladium hydroxide on carbon, Pd content 20% (2.8 g) in 100 mL of methanol was hydrogenated at 50 psi in a Parr apparatus for 4 hrs. The catalyst was removed by filtration through Celite and the filtrate was evaporated under reduced pressure to give 1,1,1-tris(hydroxyethoxymethyl)ethane (6.7 g, 0.026 mol, 99%).
