摘要： This invention provides for the separation of the contents of the process discharge stream of reaction in which an amine is produced from a nitrile. An inorganic base having a concentration greater than 40 weight percent is introduced into the process discharge stream which is decanted, purged, flashed, and a portion thereof recycled.

摘要： Packages of undivided electrolytic cells for electrochemical synthesis having a plurality of metal-plated cathodes with corresponding anodes are produced by assembling and permanently fixing the electrodes in substantially parallel-planar relationship as a package and thereafter electroplating the cathodes in package form by applying an electric potential between the anodes and cathodes in an electroplating solution containing the plating metal in complex form, the anodes functioning as non-sacrificial anodes during electroplating. Such electroplating may be accomplished in the electrochemical synthesis cells and may employ the same power application means and controls as the means and controls employed in the electrochemical synthesis.

摘要： Acrylonitrile is catalytically dimerized in the presence of an organic phosphorus (III) catalyst, an inert hydrocarbon reaction solvent and a non-interfering proton-donating solvent; and the dimerized product separated from the catalyst by extraction. In the extraction the dimerized product is preferably dissolved in an extraction solvent and removed from the catalyst phase preparation. In the instant invention, the extraction solvent is an amide, preferably formamide. The extraction solvent and proton-donating solvent may be identical.
