ABSTRACT:
A process of forming N,N-dialkylhydroxylamines (a class of compounds useful as oxygen scavengers in boiler water feed) by contacting an N-alkylhydroxylamine with an alkyl carbonyl compound to form a nitrone in situ or, alternatively, using previously formed alkylnitrone which is subjected to H.sub.2 and a hydrogenation catalyst.
