Scope
Main technical content: This document specifies the requirements, test methods, inspection rules, marking and accompanying documents, packaging, transportation, storage, etc. of tetrabromophthalic anhydride and ethylene bis tetrabromophthalimide by-product magnesium sulfate heptahydrate. This document is applicable to the sulfuric acid solution generated during the production of tetrabromophthalic anhydride and ethylene bis tetrabromophthalimide. After pretreatment, the solution is neutralized with magnesium oxide to produce magnesium sulfate solution, which is then refined to obtain magnesium sulfate heptahydrate. It is mainly used in building materials, leather making, printing and dyeing, papermaking, plastics, and other industries.
