Abstract
Significant production of elemental bromine (Br2) was observed for the first time when treating bromide containing solutions at acidic pH, with TiO2photocatalyst, ozone, or a combination thereof. Br2selectivities up to approximately 85 % were obtained and the corresponding bromine mass balance values satisfied. The process is general and may be applied at a laboratory scale for green bromination reactions, or industrially as a cheap, safe, and environmentally sustainable alternative to the currently applied bromine production methods.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
