Reaction Steps
Briefly describing one aspect of the present invention, there is provided reduced methyl bromide methods for making high yield, high quality tetrabromobisphenol-A using methanol solvents including dissolving bisphenol-A in a methanol solvent to form a bisphenol-A methanol solution, adding bromine to the bisphenol-A methanol solution to brominate bisphenol-A and form tetrabromobisphenol-A and hydrogen bromide, exposing the bisphenol-A methanol solution to an amount of a hydrogen peroxide agent to reduce the amount of methyl bromide co-product resulting from the bromination of bisphenol-A in methanol by reducing the amount of hydrogen bromide co-product available to reach with the methanol, and collecting the resulting tetrabromobisphenol-A product thus formed after the bromination is substantially complete.
