Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.
A loop reactor comprising an inline static mixer, heat exchanger, reagent feeds, a pH cascade control system configured to control a reagent feed rate through at least one reagent feed and an oxidation/reduction potential cascade control system configured to control a reagent feed rate through at least one reagent feed.
