    摘要： An electrolytic method for the simultaneous preparation of a diaryliodonium salt and an alkoxide salt comprises adding to the anode compartment of an electrolytic cell, comprised of an anode, a first electrolytic solution comprising an aromatic compound, an iodoaromatic compound, a solvent and a first organic salt; adding to the cathode compartment of the cell, comprised of a cathode, a second electrolytic solution comprising a hydroxyalkyl compound and a second organic salt; and applying to the anode and the cathode an electric potential, to form diaryliodonium salt in the anode compartment and an alkoxide salt in the cathode compartment.Esters of an aromatic acid are prepared by carbonylating an admixture of the diaryliodonium salt and the alkoxide salt by the addition of carbon monoxide thereto.

    摘要： A device for in situ cleaning a fouled membrane of a sensor disposed in an aqueous process solution includes a first electrolysis electrode disposed in the process solution immediately adjacent the membrane, a second electrolysis electrode disposed in the process solution and spaced apart from the first electrolysis electrode, and a controllable power source for passing a current between said first and second electrodes. The current produces a heavy concentration of ions at a surface of the fouled membrane. The polarity of the current is selectable to produce negative or positive ions for reacting to decompose deposited salts, or to scrub contaminates from the membrane surface.
