Electrolytic membrane recovery of bromine from waste Hydrogen Bromide streams
Aiche Journal, 1998Co-Authors: Cary N. Wauters, Jack WinnickAbstract:A novel electrochemical process was developed for the recovery of bromine from waste gas-phase Hydrogen Bromide streams. It uses a molten-salt-saturated membrane to electrolytically decompose Hydrogen Bromide into its molecular constituents, which are separated into a Hydrogen-enriched waste stream and a pure bromine product stream. Single-cell studies were carried out in a configuration consisting of two cell housings (vitreous carbon), two gas-diffusion electrodes (recirculated vitreous carbon or graphite felt), and a molten salt [(Li{sub 0.575}K{sub 0.133}Cs{sub 0.292})Br] saturated membrane (zirconia). Single-cell results at 300 C, based on process stream concentrations ranging from 25 to 75% Hydrogen Bromide at 50 to 300 mL/min, demonstrated current densities exceeding 1 A/cm{sup 2} and removals as high as 95%. Water and acetone (as a light organic contaminant) addition to the process feed, as well as exposure to thermal cycling, showed no deleterious effects on cell performance. Preliminary economics indicate this to be a viable process.

recovery of bromine from waste gas phase Hydrogen Bromide streams using an electrolytic membrane
Journal of The Electrochemical Society, 1996Co-Authors: Cary N. Wauters, Jack WinnickAbstract:An electrochemical cell is used to demonstrate a significant improvement in the recovery of bromine (Br{sub 2}) from waste gas-phase Hydrogen Bromide (HBr) streams. The continuous process operates at 300 C and utilizes reticulated vitreous carbon gas-diffusion electrodes, a molten (Li{sub 0.575}K{sub 0.133}Cs{sub 0.292})Br electrolyte, and borosilicate glass fiber membrane. HBr is simultaneously electrolytically decomposed and separated into a Hydrogen enriched waste stream and pure anhydrous Br{sub 2} product stream. Simulated industrial waste streams containing HBr, nitrogen, water vapor, and organic compounds have been tested. These results include removals of greater than 90% and current densities approaching 1.0 A/cm{sup 2}.

stereoselective Hydrogen Bromide promoted Hydrogenation of an α hydroxyoxime
Tetrahedron Letters, 2000Co-Authors: Ian W Davies, Mark Taylor, Jeanfrancois Marcoux, Louis Matty, Jimmy Wu, David L Hughes, Paul J ReiderAbstract:Abstract Hydrogen Bromide has been demonstrated to provide optimal cis -selectivity in the reduction of 4-chromanone α-hydroxyoxime (25:1 cis / trans ) in 94% yield. This reaction is pivotal in the synthesis of cis -aminochromanol.
