3-Pentanone (8.61 g, 10.6 ml, 0.1 mol), glycerol (92.09 g, 73.7 ml, 1 mol), and 10% Pd/C (5 wt %, 0.43 g) are charged to a Parr reactor, purged with nitrogen, heated to 200° C. with stirring and run at 1000 psi of hydrogen for 9 hrs. GC analysis reveals 80.2% conversion of 3-pentanone and shows selectivity to 3-(3-pentoxy)-1,2-propanediol (40.7%), 1,3-di-(3-pentoxy)-2-propanol (0.5%), 4-hydroxymethyl-2,2-diethyl-2-1,3-dioxolane (cyclic ketal) (31.4%).
