Reaction Conditions:

with hydrogen;palladium 10% on activated carbon at 180; under 51716.2 Torr; for 2 h;Product distribution / selectivity;Inert atmosphere;

Steps:

5

In Examples 1-10, n-butyraldehyde, ethylene glycol, and hydrogen are reacted in the presence of Pd/C at various ratios and/or reaction conditions. The reaction procedure is generally as follows. The n-butyraldehyde, ethylene glycol, and Pd/C are charged to a Parr reactor. The system is purged with nitrogen three times. Then hydrogen is charged, the reactor is heated, and the hydrogen pressure is adjusted as necessary. Following the appropriate reaction time, the product mixture is analyzed by GC. Reaction conditions and GC results are summarized in Table 1.
