Scope
Main technical content: This document specifies the requirements for brominated sodium produced as a by-product of the bromination reaction (for the production of brominated polystyrene and tetrabromophthalic anhydride), testing methods, inspection rules, marking and accompanying documents, packaging, transportation, and storage, etc. This document applies to the brominated hydrogen gas or hydrobromic acid produced during the bromination reaction in the production of brominated polystyrene and tetrabromophthalic anhydride. The brominated sodium obtained after absorption or neutralization with alkali solution and subsequent adsorption, filtration, crystallization, and suction filtration and drying with activated carbon is only used for industrial production.
