  • Publication number: 20130140188
    Abstract: A method of the present invention, for producing an iodizing agent, includes the step of electrolyzing iodine molecules in a solution by using an acid as a supporting electrolyte. This realizes (i) a method of producing an iodine cation suitable for use as an iodizing agent that does not require a sophisticated separation operation after iodizing reaction is completed, and (ii) an electrolyte used in the method. Further, a method of the present invention, for producing an aromatic iodine compound, includes the step of causing an iodizing agent, and an aromatic compound whose nucleus has one or more substituent groups and two or more hydrogen atoms, to react with each other under the presence of a certain ether compound. This realizes such a method of producing an aromatic iodine compound that position selectivity in iodizing reaction of an aromatic compound is improved.

  • 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.

  • Publication number: 20040104126
    Abstract: Direct bromination of hydroxy aromatic compounds by electrolysis of mixtures comprising the hydroxy aromatic compound, a source of bromide ion, and an organic solvent provides product brominated hydroxy aromatic compounds at synthetically useful rates with high para-selectivity. The process does not require the use or handling of molecular bromine or bromine complexes and allows the full use of the bromide source without generating hydrogen bromide as a by-product of the reaction. The simple electrochemical equipment required by the present process, for example an undivided electrochemical cell, makes the process less capital intensive than analogous electrochemical processes carried out in divided cells. The use of hydrobromic acid as the source of bromide ion provides clean reaction with nearly exclusive formation of the target brominated product.

  • Patent number: 5891318
    Abstract: A process and a system uses a direct chlorination reactor for producing ethylene dichloride by direct chlorination, without the need for an oxychlorination unit. This ethylene dichloride may be used to make vinyl chloride monomer. In the process for making ethylene dichloride, ethylene and chlorine are both supplied to a direct chlorination reactor. The ethylene reacts with the chlorine to form ethylene dichloride. Chlorine is supplied to the direct chlorination reactor from an electrochemical cell which converts anhydrous hydrogen chloride to dry chlorine gas. This chlorine gas is purified and liquefied to form liquid dry chlorine, and the liquid dry chlorine is recycled to the direct chlorination reactor. The ethylene dichloride may be pyrolyzed to produce vinyl chloride monomer and anhydrous hydrogen chloride.
