ABSTRACT:
A method for preparing nitrones from mixtures of arylhydroxylamines and alkylhydroxylamines containing zinc oxide solids is provided which does not require filtration of the mixture prior to reaction. This is accomplished by introducing a dilute acid solution to the mixture so as to solubilize the zinc oxide powder. The hydroxylamines within solution may be reacted with an aldehyde to produce a nitrone where the dilute acid dissolves the zinc oxide.
