Glycerol → iso-Butyraldehyde Glycerol

Participants

Reaction Conditions

Reaction Steps

iso-Butyraldehyde (7.21 g, 9.13 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 the Parr reactor, purged with nitrogen three times, heated to 200° C. with stirring and run at 1000 psi of hydrogen for 8 hrs. GC analysis shows complete consumption of iso-butyraldehyde and formation of glycerol monoethers 3-iso-butyloxy-1,2-propanediol and 2-iso-butoxy-1,2-propanediol (80.1%, ratio 8.2), glycerol diethers 1,3-di-iso-butoxy-2-propanol and 2,3-di-iso-butoxy-1-propanol (7.1%), iso-butanol (2.7%).
