Symmetrically substituted N,N-dihydrocarbylhydroxylamines are prepared in a single step by the reaction of an aldehyde and hydroxylamine hydrochloride in an alcoholic solvent in the presence of hydrogen and a hydrogenation catalyst. The free N,N-dihydrocarbylhydroxylamine is liberated from the hydrochloride salt by treatment with alkali. N,N-Dihydrocarbylhydroxylamines, particularly the N,N-dialkylhydroxylamines, are useful stabilizers for a variety of polymers.
