Abstract

Chemical compounds are prepared by passing a current through an electrolyte between a parent electrode and a counter electrode, at least part of the parent electrode being in a zone separated from the counter electrode by a pervious barrier; contacting the parent electrode within said zone with a stream of solid conductive particles containing adsorbed reactant, the reactant being converted into the desired compound electrochemically; and discharging the solid conductive particles and reaction product from the said electrode contacting zone. Typically particles of carbon, a metal such as Ag, Cu, Fe, a semi-conductor such as Si, Ge, Se, CuO, platinum-coated particles or salt particles of diameter 1m to 1 mm but preferably with a range of diameters of not more than 3:1 are fed from a hopper 28 to a mixing unit 24 where they adsorb a liquid reactant fed with an electrolyte along conduit 25 or a gaseous reactant introduced along conduit 34 and mixed by passage through a porous sleeve or a Venturi device. The resultant liquid is fed into a compartment defined by an ionpermeable diaphragm of sintered glass, ceramic or ion-permeable resin and containing the reaction electrode 12 having fingers 18. The treated material passes via conduit 17 to a separator 40 where unchanged reactant, product and electrolyte are discharged at 41 and the conductive particles are discharged at 42 for recycling, a portion of them being bled off at 43 if desired. The counter electrode 11 may be of wire mesh and the electrolyte in this compartment may be a liquid which may be changed continuously or intermittently by means of conduits 46, 47 or a paste held in a porous solid. If a non-electrolyte fluid is used to convey the reactant material and particles, the reaction electrode must be wetted with electrolyte, e.g. by making the electrode porous and using it also as the diaphragm so that the counter electrode electrolyte passes through it on to its reaction surface. Such a reaction electrode may be of porous metal or of a porous material having a reticulated inner surface the crests of which are coated with metal to provide a conductive network Fig. 8 (not shown). If desired both compartments may include reaction electrodes which may be formed by a series of grids spaced axially on a supporting rod extending in the direction of flow of the reactant, conductive particles and electrolyte Figs. (not shown). As described the process may be applied to oxidizing aldehydes to acids, reducing aldehydes to alcohols, reducing multiple bonds e.g. hydrogenating naphthalene. In a specific example nitrobenzene is reduced to aniline using platinum electrodes with an applied P.D. of catalytic silver particles of 50 to 150m and sulphuric acid electrolyte.
