Abstract: Bromine is continuously produced by simultaneously feeding an aqueous solution of bromide or hydrobromic acid and chlorine gas into the top of a contact tower which is separated into an upper reaction section and a lower distillation section, having a gas outlet port therebetween; and feeding steam from the bottom of the tower whereby free bromine formed in the upper reaction port section and free bromine distilled from the lower distillation tower section are recovered through said bromine outlet port, wherein the aqueous solution containing bromide or hydrobromic acid is heated at lower than 80.degree. C in the reaction section and the solution is heated to higher than 90.degree. C in the distillation section.
