CONTINUOUS PRODUCTION PROCESS OF BENZYL ACETATE FROM CINNAMON ESSENTIAL OIL AND THE EQUIPMENT SYSTEM USED FOR THIS PROCESS

Abstract

The invention relates to a continuous production process for benzyl acetate from cinnamon essential oil, comprising the following steps: fractional distillation of cinnamon essential oil at pressures from -94 kPa to -101 kPa to obtain benzaldehyde with a purity ranging from 98.5% to 99.9% at temperatures between 110°C and 140°C; conversion of benzaldehyde to benzyl acetate by reacting benzaldehyde with acetic acid in the presence of a catalyst at temperatures between 70°C and 90°C for 1 to 6 hours; centrifugation to remove the catalyst or solid salt from the liquid; subsequent vacuum concentration of the liquid to recover a portion of the excess acetic acid; the remaining liquid after concentration is washed with water to a neutral pH and the oil phase is separated from the water phase to obtain the crude oil phase containing benzyl acetate; Fractional distillation of the crude oil phase containing benzyl acetate under conditions of temperature from 120°C to 150°C and pressure from -94 kPa to -101 kPa yields benzyl acetate with a purity of ≥ 99%.In addition, the invention also relates to a system of equipment used for this process.
