Yield:123-76-2 95%
Reaction Conditions:
with methanesulfonic acid in water monomer at 120; for 18 h;Sealed tube;Reagent/catalyst;
Steps:
5.a; 5.b Example 5: Hydrolysis of ethyl levulinate to obtain levulinic acid. (a ) Homogeneous catalysis .
A steel batch reactor equipped with a magnetic stirrer was charged with ethyl levulinate (1.00 g) , distilled water (30 mL) and methanesulfonic acid (153 mg, 15.3% w/w) . Subsequently the reactor was sealed and the reaction mixture heated under stirring (200 rpm) at 120°C for 18 h. Once the reaction was complete, the reactor was cooled to room temperature and the reaction mixture filtered (porosity 0.45 pm) to obtain a clear solution. Molar yield (95%) and conversion (95%) were determined by analyzing a sample of the reaction mixture by HPLC method
