Portuguese Abstract: In this work a synthetic process applied for Passiflora edulis Sims f. flavicarpa Degener aiming its oil epoxy reaction in the presence of performic acid, generated in situ. was developed for its biotechnological improvement. In that, a mathematical model with four factors, two-level 24-1 fractional factorial design, was employed varying temperature, reaction time, as well formic acid and hydrogen peroxide ratio. The selectivity, thermodynamic and kinetic for this epoxy reaction was also analyzed varying temperature (30° C to 70° C). In the experimental synthetic results it was observed that 2h reaction was necessary, under 50° C in the presence of H2O2/C=C/HCOOH (1:1:1) affording 88.05% ± 0.5 for the Passiflora edulis oil synthetic conversion and for 3h the semisynthetic epoxy derivative in the same conditions, requires 30° C (83.09% ± 0.5) avoiding oxirane ring cleavage and undesirable secondary products formation. The applied approach showed to be efficient for reactions conditions optimization in that synthetic epoxidation. The obtained semisynthetic epoxy derivative is herein described and will be replaced in the oils research progress, as a new target for chemical manufacture
