実験手順
n-Decanal (3.9 g, 4.7 ml, 0.025 mol), tetraethylene glycol (97.1 g, 86.3 ml, 0.5 mol) and 10% Pd/C (0.2 g, 5 wt % to n-decanal) 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 the hydrogen pressure is adjusted to 1000 psi. After 3 hours at 200° C. and 1000 psi, GC analysis shows complete conversion of n-decanal and detects 3,6,9,12-tetraoxa-1-docosanol (79.4%) and n-decanol (15.3%).
