Title:
METHOD OF IMPROVED DIMERIZATION OF OLEFINE COMPOUND BY ELECTROLYTIC HYDROGENATION
Document Type and Number:
Japanese Patent JPS5315312
Kind Code:
A
Abstract:
An improvement in an electrolytic hydrodimerization process for hydrodimerizing an olefinic compound such as acrylonitrile to form a dimerized product such as adiponitrile in which an aqueous electrolyte solution comprised of the olefinic compound, a directive salt (providing quaternary ammonium cations) and a conductive salt is electrolyzed in a reaction cell, the aqueous solution is purged from the reaction cell, and subjected to a series of steps involving the recovery of the product, the directive salt and the conductive salt, the recovered salts being used to reconstitute the aqueous solution, the improvement being a functionally coordinated evaporation step which permits a higher rate and more efficient recovery of product and salts, a higher purge rate and a substantially higher yield of the dimerized product. The invention also constitutes an improved electrolyte recovery process.
