Abstract: Purchase of items is facilitated though use of a wireless device. The wireless device connects to a server via a global communications network. The consumer's shopping list is maintained on the server and displayed on the wireless device. Using the wireless device and the shopping list, a checkout list is created by entering or scanning codes on selected items at locations proximate the selected items in a store. One or more of the locations proximate the selected items corresponds to a location that is different from a point of sale in the store, the point of sale corresponding to a location in the store where goods on the checkout list are purchased using the wireless device.

Abstract: Treatment of dicyanobutene to inactivate residual dimerization catalyst facilitates hydrogenation of the product to form adiponitrile.

Abstract: An improvement in the process of electrohydrodimerizing acrylonitrile to adiponitrile wherein metal-plated cathodes, which are employed in the process as a part of an electrolytic cell, are pretreated by wetting the cathodes with aqueous phosphoric acid thereby to significantly reduce fouling.

Abstract: 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.

Abstract: Propionitrile is subject to oxidative dehydrogenation at high temperatures in the presence of a stoichiometric excess of a metal oxide oxygen donor to produce acrylonitrile at a high rate of conversion and selectivity.

Abstract: An improvement in the process of electrohydrodimerizing acrylonitrile to adiponitrile wherein the plated electrodes, which are employed in the process as a part of an electrolytic cell, are, without removal from the cell, cleaned and replated.

Abstract: 4-cyano-suberonitrile is continuously converted to acrylonitrile in a catalyst-free reaction at temperatures of about 700.degree.-800.degree. C.
