ELECTROSYNTHESIS OF SOLID TETRA ETHYL AMMONIUM TRIBROMIDE (TEATB) IN A MEMBRANE ELECTROLYZER
The conventional method of bromination of organic compounds by direct handling of liquid bromine is hazardous and environmentally unacceptable. Solid organic tribromide compounds are substituted in the place of liquid bromine for bromination reactions. Tetra ethyl ammonium tribromide (TEATB) was synthesized in an electrochemical membrane electrolyzer with 8082% current efficiency at 50 degrees C using IrO2/Ta2O5-coated titanium anode, nickel-expanded mesh cathode, and Nafion 961 membrane.
