Abstract

Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas.
N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert or-ganic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporisation of the solvent, so limiting in-creases in reaction temperature and suppressing the dissociation of the N2O5.
In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recirculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.
