Ethyl levulinate synthesis

13synthesis methods
Usually obtained by direct esterification of levulinic acid with ethanol and H2SO4 in benzene or in toluene; also in the presence of HCI in ethanol; other methods starting from glucose, fructose and others are of less importance.
-

Yield:539-88-8 100%

Reaction Conditions:

with Zirconium Exchanged Phosphotungstic Acid at 120; for 2 h;Temperature;

Steps:



LA esterification was carried out in a 15 mL pressuretube. In a typical experiment, LA (0.116 g) was mixed in ethanol (3 mL) and 0.05 g of catalyst was added in the tube.The reaction mixture was heated to desired temperature andmagnetically stirred at 350 rpm. After completion of thereaction, the reaction mixture was centrifuge to remove thecatalyst. The products were analysed by a Gas chromatographwith DB-5 capillary column (M/s Shimadzu, Japan)equipped with flame ionization detector (FID).
