【 摘 要 】

This work presents an optimized integrated experiment for isolation of clove bud essential oil, rich in eugenol, and subsequent utilization of the solid residue for furfural synthesis. The operationally simple laboratory protocols and utilization of water as a solvent in both operations, plus the use of biomass as the starting material for preparation of versatile intermediates in organic synthesis, make the experiments attractive for undergraduate experimental organic chemistry courses in the context of green chemistry. In addition, this is the first description of the use of biomass (clove bud) in the simultaneous preparation of two chemical feedstocks, eugenol and furfural, on experimental organic chemistry courses.
