Reaction Conditions

Reaction Steps

n-Butyraldehyde (3.6 g, 4.5 ml; 0.05 mol), diethylene glycol (106.1 g, 55.8 ml; 1 mol), and 0.18 g of 10% Pd/C are charged to a 150 ml Parr reactor. The system is purged with nitrogen three times. Then 500 psi of hydrogen is charged, the reactor is heated to 200° C., and set 1000 psi of hydrogen. After 2 hrs at 200° C. and 1000 psi, GC analysis shows complete consumption of n-butyraldehyde and formation of 3,6-dioxa-1-decanol (n-butyl carbitol) (94.5%), n-butanol (3.4%) and 2,2′-dibutoxy ethyl ether (2.1%).
