摘要: A process for dehalogenation of alpha halogenated carbonyl compounds and/or the prevention of the formation of such. The process for dehalogenation generally comprises causing there to be in solution the halogenated compound, cuprous ions (such as from cuprous chloride) and hydrogen ions (such as from hydrochloric acid), the process to be conducted in the absence of molecular oxygen, or, if molecular oxygen is present, there being an excess of cuprous ions sufficient to completely react with the molecular oxygen present. Such can also be used to suppress formation of halogenated carbonyl compounds in processes where conditions exist which favor such formation.

摘要: An aqueous nitric acid solution derived from an adipic acid process containing copper and vanadium catalyst values and alkyl dicarboxylic acids is treated to remove the nitric acid and water therefrom so as to obtain a substantially dry, molten-type residue. This residue is mixed with a dialkyl ketone solvent which dissolves the dicarboxylic acids and leaves the catalyst metal values as solids.
