Procedure

A 5 cc autoclave is charged with 1 cc of heptane 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-butene and heated to 150° C. for 0.5 hours while maintaining a constant pressure of isobutene. After cooling, the organic phase is separated. A mixture of butyl formate and butyl levulinate is formed as product.
