iso-Valeraldehyde (8.61 g, 10.8 ml, 0.1 mol), glycerol (92.09 g, 73.7 ml, 1 mol), and 10% Pd/C (5 wt %, 0.43 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 iso-valeraldehyde and formation of glycerol monoethers 3-iso-pentoxy-1,2-propanediol and 2-isopentoxy-1,2-propanediol (82.0%, ratio 8.5), glycerol diethers 1,3-di-isopentoxy-2-propanol and 2,3-di-isopentoxy-1-propanol (8.4%), iso-pentanol (6.3%).
