Conditions

Temperature
100 °C

Procedure

A 5 cc autoclave is charged with 2 cc of an aqueous solution containing 0.5 mmoles of levulinic acid and 2 mmoles of formic acid. 15 wt. % ZSM-5 zeolite is added as a catalyst. The reactor is pressurized to 0.69 MPa with 1-butene and heated to 100° C. for 4 hours while maintaining a constant pressure of 1-butene. After cooling, the organic phase is separated. A mixture of butyl formate and butyl levulinate is formed as product.
