Versuchsvorschrift
Acetone (5.81 g, 7.34 ml, 0.1 mol), glycerol (92.09 g, 73.7 ml, 1 mol), and 10% Pd/C (5 wt %, 0.29 g) are charged to a Parr reactor, purged with nitrogen, heated to 200° C. with stirring and run at 1000 psi of hydrogen for 4 hrs. GC analysis reveals complete consumption of acetone and shows presence of glycerol monoether 3-isopropoxy-1,2-propanediol (78.5%), glycerol diethers 1,3-di-isopropoxy-2-propanol and 2,3-di-isopropoxy-1-propanol (3.9%), iso-propanol+acetone (7.2%).
Aufarbeitung
- custompurged with nitrogen
