n-Butyraldehyde (7.21 g, 8.96 ml, 0.1 mol), glycerol (92.09 g, 73.7 ml, 1 mol), and 10% Pd/C (5 wt %, 0.36 g) are charged to a Parr reactor, purged with nitrogen three times, heated to 200° C. with stirring and run at 1000 psi of hydrogen for 4 hrs. GC analysis shows complete consumption of n-butyraldehyde and formation of glycerol monoethers, 3-butyloxy-1,2-propanediol and 2-butoxy-1,2-propanediol, (83.1%, ratio 6.7), glycerol diethers 1,3-dibutoxy-2-propanol and 2,3-dibutoxy-1-propanol (7.1%), n-butanol (3.3%), di-n-butylether (0.3%).
