  • Patent number: 7052593
    Abstract: The present invention provides an electrochemical method for producing diaryl iodonium compounds wherein application of an electric current to an electrochemical cell containing a reaction mixture composed of a solvent, an iodoaryl compound and an electrolyte forms an oxidizing agent in situ. In this first step, the oxidizing agent is subsequently converted into a stable oxidized iodoaryl intermediate, typically an iodosyl compound. The electric potential is removed and in a second step a target aryl compound is introduced to the reaction mixture to react with the oxidized iodoaryl intermediate to form a diaryl iodonium compound.

  • Patent number: 6756013
    Abstract: The present invention provides a composition having biological activity. The composition includes from about 10 ppm to about 5000 parts iodonium salt. The composition also includes from about 100 ppm to about 300,000 ppm of a compound to act as a carrier of the iodonium compound. The carrier is selected from at least one of polyvinyl alcohols, polyvinyl acetates, polyethylene glycols, ethylene glycol and propylene glycol block copolymers, cellulosic polymers, polyesters, alkyd polymers. The composition also includes from about 50 ppm to about 50,000 ppm of a compound to render the composition compatible with a surface being treated. This component is selected from at least one of di-acids, acid anhydrides, polyfunctional acids, di-ethylene glycol, resorcinol and the like. The composition also includes an appropriate vehicle selected from at least one of water, acidified water, paint, primer, and petroleum distillates.

  • Patent number: 6620305
    Abstract: An electrolytic process for the preparation of a compound having a charged electrolytic cell fitted with at least one anode and at least one cathode in a single compartment with a reaction mixture. An electric potential is applied to the at least one anode and at least one cathode under conditions to promote formation of a compound on one of the cathodes or the anode to define a formation electrode. The formation electrode is then agitated.
