Reaction Steps
A 5 cc autoclave is charged with 1 cc of iso-octane and 1 cc of an aqueous solution containing 2 mmoles of levulinic acid and 2 mmoles of formic acid. 5 wt. % sulfuric acid is added as a catalyst. The reactor is pressurized to 0.69 MPa with 1-pentene and heated to 75° C. for 5 hours while maintaining a constant pressure of 1-butene. After cooling, the organic phase is separated. A mixture of pentyl formate and pentyl levulinate is formed as product.
