2-Undecanone (8.5 g, 10.3 ml; 0.05 mol), ethylene glycol (62.1 g, 55.8 ml; 1 mol), and 0.2 g of 10% Pd/C are charged in the 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 adjusted to 1000 psi. After 3 hrs at 200° C. and 1000 psi, GC analysis shows 98% conversion of 2-undecanone and formation of 2-sec-undecylethanol (87.1%), 2-undecanol (7.0%), and 2-methyl-2-nonyl-1,3-dioxolane (0.9%).
