Versuchsvorschrift
2-Methylundecanal (4.61 g, 5.55 ml, 0.025 mol), triethylene glycol (75.1 g, 66.8 ml, 0.5 mol) and 10% Pd/C (0.3 g, 6.5 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 are 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 99.7% conversion of 2-methyl-undecanal and detects 11-methyl-3,6,9-trioxa-1-eicosanol (76.3%) and 2-methyundecanol (11.9%).
