ABSTRACT:
An improved process for oximation of carbonyl compounds, such as ketones and aldehydes by oximation with hydroxylamine including oximation processes carried out in the presence of a catalytic amount of a phase transfer catalyst comprised of a mixture of an alkyl phenol, such as nonylphenol or dodecylphenol and an organic carboxylic acid, such as 2-ethylhexanoic acid, in the presence of an alkali metal or alkaline earth metal compound. The resulting oximes are useful as metal extractants.
