Abstract:

       This paper addressed preparation methods of dihydrocarvone, dihydrocarveol and dihydrocarvyl acetate with carvone as raw material and such steps as reduction, esterification, especially the ZnROH reduction. We employed NMR and ESIMS to determine the structures of these objective compounds. This synthesis process has such positives as low cost and high recovery rate (more than 80%), and has some references to industrial production.

Key words: carvone, spice, synthesis
