<p>A continuous process for the production of diacetate derivatives of aromatic compounds, comprising feeding at any convenient temperature an oxygen-containing gas and feedstock comprising a diisopropyl ring substituted aromatic compound and the recycled monoisopropyl-monoacetate derivative thereof, to an oxidizer operated, for example, at from about 10°C to about 150°C and oxygen partial pressures of from about 0.05 to 10 atmospheres to form an oxidizer product comprising the mono- and dihydroperoxides of the feedstock, feeding the oxidizer product to a rearrangement-esterification zone containing acetic anhydride at from about 0°C to 150°C to form an ester product comprising the diacetate and monoisopropyl-monoacetate derivatives of the feedstock, distilling the ester product to separate the diacetate and monoisopropyl-monoacetate derivatives, and recycling the monoisopropyl-monoacetate derivative back to the oxidizer.</p> |
