Abstract: A study was performed of the relative reactivity of vapors of a number of acetic acid esters (alkyl acetates) with respect to plasma components of a pulsed corona discharge with the voltage of 100 kV and duration of 40 ns. On model mixtures based on methyl-, ethyl-, propyl-, isopropyl-, isobutyl-, butyl-, and vinyl acetates with contents of 250–500 ppm in air and nitrogen, the relative reactivity parameters were obtained. The reactivity of acetic acid esters increases with an increase in the hydrocarbon substituent. The high reactivity of vinyl acetate is due to the double bond reaction with ozone.

Keywords: corona discharge, acetic acid esters, alkyl acetates, vinyl acetate, non-equilibrium atmospheric-pressure plasma, air purification, volatile organic compounds.
