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 an acid phase transfer catalyst, such as 2-ethylhexanoic acid, and/or the presence of an alkali metal or alkaline earth metal catalyst. The resulting oximes are useful as metal extractants.
