실험 절차

This patent discloses a process in which the 1,2 epoxide of limonene is refluxed with acetic acid and acetic anhydride to yield the 1,2 diacetate of limonene and the excess of these esterification reagents is removed. The diester product of pyrolysed by heating at atmospheric pressure at an elevated temperature. The carvyl acetate is obtained by fractional distillation of the resulting mixture.
