How to Use Ethyl levulinate

Ethyl levulinate is a colourless to pale yellow liquid with apple odour.

Sulfonic acid-functionalized ionic liquids are charismatic and foretelling catalyst for the conversion of sugars to ethyl levulinate and ethyl-D-glucopyranoside in ethanol.

These task-specific ionic liquids can be recovered and reused in at lowest three cycles/seconds in the conversion of fructose to ethyl levulinate without any loss of activity.

Sulfonic acid functionalised SBA-15 (SO3H-SBA-15), sulfated zirconia and beta, Y, ZSM-5 and mordenite zeolite catalysts have been applied for the dehydration of sugars to ethyl levulinate and ethyl-d-glucopyranoside (EDGP) using ethanol as solvent and reactant. The SO3H-SBA-15 catalyst showed a high catalytic activity for the selective conversion of fructose to ethyl levulinate (57%) and glucose to EDGP (80%) at 140 °C, whereas the disaccharide sucrose gave way a earthshaking sum of money of both products. The SO3H-SBA-15 catalysts were found to be highly active compared to the zeolites under identical reaction conditions.

Ethyl levulinate is also called      Levulinic acid ethyl ester 4-oxopentanoate; 4-Oxopentanoic acid ethyl ester; Ethyl laevulinate; Ethyl Ethyl 4-oxovalerate; Ethyl 4-ketovalerate; Ethyl 3-acetylpropionate.
